Welcome to PowerCAD Welcome to PowerCAD. PowerCAD gives you the power to design schematics starting from the initial idea to the final drawing. These are just a small description of the kind of schematics you can do with PowerCAD: * hydraulics, * pneumatics, * ladder, * electrical, * grafcet, * HVAC. 2.1. How PowerCAD Works When you start working on a drawing, you'll usually begin by deciding on the components you're going to place on the drawing. To place components on the drawing you can either choose them from the symbol menu or import them from an already defined block. PowerCAD is versatile. You can define components that are not supplied in the standard menu, and with these components you can define as many blocks as you want. As you build the diagram, you'll have to connect symbols together. The ROUTER will help you to connect the pieces together. The ROUTER is an intelligent piece of software that will permit you to optimize the flow of lines between CONNECTION POINTS. You'll have the possibility to move, rotate, flip, delete components from the drawing. These operations will trigger the ROUTER to optimize again the flow of lines. You'll have the possibility to see your drawings at any scale you want with the ZOOM commands. When you want to have a copy of your drawing, just select the command PRINT and you'll obtain a print of the drawing and/or the PART LIST. 3 Powercad User Manual 3. Before You Begin This section explains what you need to do before you can start using PowerCAD, and how you can begin to learn to use it. 3.1. What You Need to Run PowerCAD To run PowerCAD you need the following hardware and software configuration: * an 80x86 computer with a hard disk and a floppy disk drive, * at least 2 Mbytes of free space on your hard disk, * EGA or VGA screen and card, * 640K of memory, * a MicroSoft compatible mouse, * a printer (9 pin, 24 pin or Laser), * DOS. Note: You don't need a math coprocessor to run PowerCAD, but if you have one the performance of the software will improve greatly. (4 to 7 times faster) 3.2. The Licence Agreement By using this program you indicate your acceptance of the following conditions: You agree to use PowerCAD entirely at your own risk, and will indemnify and hold harmless its author and distributors against any action resulting from the use of PowerCAD. The author and distributors of PowerCAD do not warrant it fit or suitable for any particular purpose. You agree that PowerCAD is protected by Canadian, U.S. and international copyright law, and is the property of Paul Guimond and Simulation Soft Expert inc. 3.3. Backing Up the Master Disk Before you install PowerCAD, you should make a backup copy of the master disk. We suggest that you use the Microsoft Windows File Manager to help you back up the master disk. 4 Powercad User Manual 4. Installation You must install PowerCAD on your computer before you can use the software. This section describes how to install and run PowerCAD. 4.1. Before You Start Before you start the installation procedure, you should: * back up the PowerCAD master disk, * read this section, * insure that your computer meets the requirements for PowerCAD. 4.2. Installing PowerCAD PowerCAD does not have a complicated installation process. Setting up to run on your system simply consists of running the setup program, which unpacks and installs the files. INSTALL.EXE will transfer the necessary files from the master disk to the working directory of your hard disk. To install the program: 1. insert the master disk in the disk drive, 2. call the program from the disk. INSTALL [ENTER] Note: PowerCAD will be installed on a hard disk, it needs 2 MBytes of space to run. 4.3. Starting PowerCAD To start PowerCAD, type POWERCAD [ENTER] The first thing you see is the introductory screen. Press [ENTER]. 5 Powercad User Manual 5. Starting Work This section covers the information you need to start drawing with PowerCAD, from finding your way in the menu, to loading and saving drawings. 5.1. Using the Mouse The following terms are used in this User's manual to indicate to you what you should do with the mouse: Click Press and release the left mouse button. Cancel Press and release the right mouse button. Drag Hold down the left mouse button and move the mouse. Select Position the mouse pointer and click the left mouse button. 5.2. The PowerCAD Window The PowerCAD window contains all the tools and commands you need to create professional looking schematics. [Figure 1 The PowerCAD Window] 6 Powercad User Manual 5.2.1. The Status Line On the status line, you will find information about: * the free memory, (100% when you start) * the operation you are doing, * the position of the mouse. (X,Y) If you look at the free memory index during the construction of a schematic, you will notice it decreasing. The maximum number of components you can put on a drawing is 1000 (if all the memory is availiable for the schematic). 5.2.2. The Menu In the menu you will find the command that you can select to produce a drawing. To select a command, just move the mouse to a menu item, you will see a yellow box around the command you are pointing at, and click on the mouse. You can't select the dashes in the menu. We have put dashes in the menu to make logical groups of commands. 5.2.3. The Work Area The whole screen is the work area. When you select a command from the menu, the menu disappear. You can use the whole screen to make your schematics. 7 Powercad User Manual 5.3. Getting Started The first step to creating a schematic is to load an existing drawing, and make modification on it, or create a new one. 5.3.1. Opening an Existing Drawing If you want to load an existing drawing you must: 1. select LOAD in the menu, 2. select the name of the file in the file selector, 3. click on the name of the file you want. Note: When you scroll in the file selector, the drawing you are pointing to with the mouse is shown in the preview box at the right of the screen. At any time, you can cancel the LOAD operation by pressing the right mouse button. [Figure 2 Loading a File] 8 Powercad User Manual 5.3.2. Starting a New Drawing If you want to start with a new page you must: 1. select LOAD in the menu, 2. select the NEW.#00 in the file selector, 3. click on. Note: NEW.#00 is a drawing file with nothing inside. When you load it, you are erasing all the working memory. If you don't have this file, you can create it by saving an empty drawing. 9 Powercad User Manual 5.4. Zooming and Panning Zoom is like a magnifying window you move on the drawing. To see more of the drawing, but with less detail, you must reduce the zoom scale. To zoom on a specific detail, you will have to increase the zoom scale. When PowerCAD starts, the zoom factor is equal to 1 and the coordinate of the lower left corner of the screen is set to 0,0 and is called the origin. You can modify the zoom factor and the coordinate of the lower left corner with the four zoom commands. The four zoom commands are: * PAN * ZOOM ALL * ZOOM SCALE * ZOOM WINDOW PAN The PAN command will change the position of the viewing window on the current display. You will have to designate two points with the mouse. The first point is the starting point for the displacement. The second point is the destination point. When you have selected the two points, PowerCAD will regenerate the drawing. Note: The selection of the second point is made by dragging the mouse to the destination point. ZOOM ALL When you select the ZOOM ALL command, PowerCAD will regenerate the drawing to display the entire drawing in the largest scale possible while still fitting it on the screen. ZOOM WINDOW When you select the ZOOM WINDOW command, you will have to designate two points with the mouse. The first point is the first corner of the window. The second point is the other corner of the window. When you have selected the two points, PowerCAD regenerates the drawing by fitting the window you have selected inside the screen. Note: The selection of the second point is made by dragging the mouse to the second corner of the window. You will see a dotted box enclosing the view area to zoom. 10 Powercad User Manual ZOOM SCALE With the ZOOM SCALE command, you can directly input the zoom factor for the drawing. After you have selected the command, you will see a dialog box where you will input the new zoom factor. The value you will enter is a relative value. If you enter 0.6 you will reduce the zoom factor to 60% of the previous value. If you enter 2.3 you will multiply the zoom factor by 2.3. [Figure 3 ZOOM SCALE] 5.5. Saving a Drawing If you want to save the drawing you are working on, you must: 1. select SAVE in the menu, 2. type the name of the file in the dialog box. The name of the file can have up to eight characters. The extension is automaticaly given by PowerCAD. As an example when you first save a drawing, you give it the name "ABCD". PowerCAD will append to the drawing the extension "#00". The second time you give a drawing the same name, PowerCAD will append the extension "#01". The third time the extension will be "#02"... 11 Powercad User Manual 5.6. Quitting PowerCAD If You want to quit PowerCAD, select Quit in the menu. When you quit, PowerCAD will save a copy of the drawing you are working on. The name of the backup copy is "QUIT.###". This file is always overwritten by a new one when you quit PowerCAD. 12 Powercad User Manual 6. Adding and Editing Components In this section are the commands you can use to make your schematics. These commands work with the intelligent ROUTER to give you the highest performan- ce in your CAD work. 6.1. Adding Adding components to the drawing is like adding real components in a control pannel or an assembly. PowerCAD see the components as components and not as a group of lines. If you select the single acting cylinder, PowerCAD will know it is drawing a single acting cylinder and also where the insertion point and the connection point are in the drawing. 6.1.1. COMPONENTS When you want to insert a new component in the drawing, you must select COMPONENTS or CUSTOM SYMB. We give you a standard library of 200 components you can use. If you need components who are not there, you can create them with the program SYMBOL. You can create 200 symbols and use them in your schematics. After you have choosen the command, a graphic menu will display 25 symbols on the screen. To select one of them, just select the symbol with the mouse. The menu will dissappear and you will see the component drawn in shadow on the screen. Move the component to its insertion, point and click the mouse. After you have inserted the component you will see another component in shadow. If you want to insert it, just move it to its insertion point and click the mouse. If you don't want it, just cancel with the mouse. If the component you want is not on the graphic menu, you can scan the pages of the menu with the number keys 1-8. When you press on 1, you will see what is on page 1. As you add components to the drawing, you will note a number that is inserted near the component. This number shows the uniqueness of the component. Each component has a number and it cannot be repeated. Two components can't have the same number. Special note: If you pick a connection point (the symbol made with a filled circle on pages 2 and 6 of the menu) and you place it over a line, the line will be broken into two parts and the two parts will be connected to the new connection point that you have just inserted. 13 Powercad User Manual 6.1.2. TEXT You can insert text to add information to your drawing. A string of text is treated like a component of the schematic. To add text to the drawing, select the TEXT command. The first thing to do is to click the mouse where you want to insert text. Afterwards you will see a dialog box in which you will input the text you want to display along with the size. The maximum length of the text is 20 characters and you can input letters, numbers and special characters. There is no restriction on the size. You can cancel the command with the right mouse button. [Figure 4 TEXT command] 6.1.3. LINE This command shows you the power of PowerCAD. The LINE command uses one of the most powerful piece of drawing software you have seen until now, we call it the ROUTER. To select, go on the LINE command and click the mouse. 14 Powercad User Manual To connect two components, just point the mouse near the first connection point and click. You don't need to be on the point, the ROUTER will find the nearest point. You will see a shadow line between the first connection point and the mouse position. Go near the second connection point and click the mouse. The ROUTER draws two lines. The first line goes horizontally from the first connection point to the horizontal position of the second connection point. The second line goes vertically from the second connection point to the vertical position of the first connection point. If you invert the order of selection of the connection points, you obtain a different path for the line. The ROUTER selects the kind of line it must draw. If the two connection points are of the power type, the ROUTER draws a full line. If one of the point is of the pilot type, the ROUTER draws a dashed line. The ROUTER will not connect mixed types of connection points, like electrical type and power type. The ROUTER will generate all the loop for lines passing over other lines. [Figure 5 LINE command] 15 Powercad User Manual 6.2. Editing The editing commands act upon components allowing them to be moved, deleted, rotated, flipped, scaled, colored or combinations thereof. These commands work in combination with the ROUTER so you can quickly see the results of you action on the lines and the network. 6.2.1. MOVE This command translates the selected component into a new position. To move a component: 1. select MOVE in the menu, 2. go onto the component you want to move and click the mouse, 3. move the component to the new location and click the mouse, 4. go onto another component you want to move or cancel with the mouse. Shadow moving occurs with the movement of the selected component. when you click the mouse on the new location of the component, you will see a regeneration of the drawing to update the new positions of the connecting lines. You can't move lines alone. [Figure 6 Moving a component] 16 Powercad User Manual [Figure 7 Regenerating the drawing after MOVE] 6.2.2. FLIP This command will cause the selected component to be flipped across the vertical axis. To flip a component: 1. select FLIP in the menu, 2. go onto the component you want to flip and click the mouse, 3. go onto another component you want to flip or cancel with the mouse. You can't FLIP TEXT. 6.2.3. ROTATE This command will cause the selected component to be rotated 90 degrees counter-clockwise. To rotate a component: 1. select ROTATE in the menu, 2. go onto the component you want to rotate and click the mouse, 3. go onto another component you want to rotate or cancel with the mouse. 17 Powercad User Manual 6.2.4. SCALE This command will cause the selected component to be scaled to one of the seven standard scale factor { 8, 4, 2, 1, 1/2, 1/4, 1/8 }. To scale a component: 1. select SCALE in the menu, 2. go onto the component you want to scale and click the mouse, 3. go onto another component you want to scale or cancel with the mouse. When you SCALE a component, PowerCAD will double the size of the component. When the component is eight times bigger than the standard size and you try to scale it, the component will be sized at 1/8 of standard size. Part number is shown only when the scale of the components is equal to 1. If you want to SCALE TEXT, see the command EDIT. [Figure 8 Edit commands] 18 Powercad User Manual 6.2.5. COLOR This command will cause the selected component to be colored with one of the sixteen standard colors { Black, Blue, Green, Cyan, Red, Magenta, Brown, Light Gray, Dark Gray, Light Blue, Light Green, Light Cyan, Light Red, Light Magenta, Yellow, White }. To color a component: 1. select COLOR in the menu, 2. go onto the component you want to color and click the mouse, 3. go onto another component you want to color or cancel with the mouse. When you COLOR a component, PowerCAD will scroll through the sixteen colors to assign the color to the component. 6.2.6. DELETE This command will cause the selected component to be deleted from the schematic. To delete a component : Be sure of what you are doing, because there is no UNDO command. 1. select DELETE in the menu, 2. go onto the component you want to delete and click the mouse, 3. go onto another component you want to delete or cancel with the mouse. Lines who connect to the component you DELETE will also be deleted. If you want to delete a LINE, go onto the point where the line bends and click the mouse. 19 Powercad User Manual 7. Using blocks Blocks are standard circuits that enclose symbols and connecting lines. With blocks you can design complex schematics from standard circuits. Blocks are easy to create and manipulate and they give you the power to customize your working environment. 7.1. Loading a Block Loading a block is like loading a file ,except that you don't erase the working memory. It is a merge of the block and the schematic in the working memory. If you want to load a block you must: 1. select BLOCK LOAD in the menu, 2. select the name of the block in the file selector, 3. click on the name of the file you want, 4. select the insertion point of the block. Notes: When you scroll in the file selector, the block you are pointing to with the mouse is shown in the preview box at the right of the screen. At any time, you can cancel the BLOCK LOAD operation by pressing the right mouse button. 7.2. Saving a Block Saving a block gives you the opportunity to save standard circuits as building blocks for bigger schematics. It increase your design speed. If you want to save a block, you must: 1. select BLOCK SAVE in the menu, 2. type the name of the file in the dialog box, 3. you select the block you want to save by dragging the mouse over it, 4. you put the mouse where you want the insertion point and click on the mouse. The name of the file can have up to 8 characters. The extension is automaticaly given by PowerCAD. The extension is "CIR". 20 Powercad User Manual 7.3. Moving a Block This command translates the selected components into a new position. To move a block of components: 1. select BLOCK MOVE in the menu, 2. you select the block you want to move by dragging the mouse over it, 3. you click on the starting point of displacement, 4. you drag the mouse to the ending point of displacement. 21 Powercad User Manual 8. The Function Key Commands We have included four commands you can access through the function keys. These commands have been put in the function keys because they are used less often than the commands in the menu. 8.1. Grid The grid is visibly represented by a dot at each 1/8" in the horizontal and vertical directions. The grid can be turned on and off by hitting the [F7] key when the menu is on the screen. When the zoom is too small, PowerCAD doesn't generate the grid. 8.2. Loop The ROUTER put loops automatically over wires and lines who cross each other but are not connected. The loops can be turned on and off by hitting the [F8] key when the menu is on the screen. 8.3. Part Number Part number are automatically generated by PowerCAD. The part number is shown with the component on the schematics. You may turned this representa- tion on and off by hitting the [F9] key when the menu is on the screen. 8.4. DXF Transfer This command allows you to transfer the schematic you work on in a format other CAD can read. The standard we use for the transfer is the Data Exchange Format or DXF. To transfer the schematic you are working on: 1. press the [F10] key, 2. enter the name of the file in the dialog box. Notes: * The extension ".DXF" is automatically appended to the name of the file. * You can export DXF file but you can't import a DXF file in PowerCAD. If you want to import a DXF file in PowerCAD, you must use SYMBOL to convert the DXF file to a symbol you can use with PowerCAD. 22 Powercad User Manual 9. New Symbols PowerCAD comes with 200 standard symbols. Some of the symbols are for electrics, ladder or GRAFCET, but the majority of them are for fluid power. We could not include all the symbols you might encounter in your field, so we give you the opportunity to create your own custom symbols. You can create 200 symbols, and use them in your schematics. 9.1. Designing Custom Symbols To design custom symbols you need the symbol editor named SYMBOL. SYMBOL is a small CAD with only the basic drawing functions. You can draw circle, arc, line, arrow. You can also import the entities part of DXF files you have made with AutoCAD or any other CAD which produces DXF files. 9.1.1. The SYMBOL Screen The working area of SYMBOL is 3.25"x2.5". It give you a lot of space to design complex symbols. At the upper right corner of the screen, you will see the coordinates of the position where the mouse is pointing. You also have a grid to help you do the design of your symbols. [Figure 9 The SYMBOL Window] 23 Powercad User Manual 9.1.1.1. Circle The first tool we will see is the circle. With this tool, you can produce circles on the screen. You can have up to 50 circles in a symbol. To draw a circle: 1. select the circle symbol in the menu, 2. click the mouse to indicate the center of the circle, 3. drag the mouse to show the radius of the circle, 4. when you have finished drawing circles, cancel with the mouse. 9.1.1.2. Arc The second tool is the arc. With the arc tool, you can produce part of a circle on the screen. You can have up to 50 arcs in a symbol. To draw an arc: 1. select the arc symbol in the menu, 2. click the mouse on the first point of the arc, 3. click the mouse on the middle point of the arc, 4. click the mouse on the last point of the arc, 5. when you have finished drawing arcs, cancel with the mouse. 9.1.1.3. Line The third tool is the line. With the line tool, you will produce straight lines at any angle on the screen. You can have up to 150 lines in a symbol. To draw a line: 1. select the line symbol in the menu, 2. click the mouse on the first point of the line, 3. drag the mouse to the second point of the line, 4. when you have finished drawing lines, cancel with the mouse. 24 Powercad User Manual 9.1.1.4. Arrow The fourth tool is the arrow. With the arrow, you will produce straight lines at any angle on the screen, and on one side of the line you will get an arrow. You can have up to 50 arrows in a symbol. To draw an arrow: 1. select the arrow symbol in the menu, 2. click the mouse on the first point of the arrow, 3. drag the mouse to the second point of the arrow (on this side you will see the tip of the arrow), 4. when you have finished drawing arrows, cancel with the mouse. 9.1.1.5. Fill The fifth tool is the fill. The fill gives you the opportunity to put a plain fill in a part of the symbol. The part you put the fill in must be closed. If it is not closed, your are going to fill the whole symbol and the schematic. You can have up to 50 fills in a symbol. To fill a part of the symbol: 1. select the fill symbol in the menu (the box filled in white), 2. click the mouse in the region you want to fill (it must be a closed region), 3. when you have finished filling, cancel with the mouse. 9.1.1.6. Selection The selection box (the box with the two lines inside) must be used at two different times when you edit a symbol. The first time you use it is to select the symbol you want to edit. Symbols are shown in group of 25. If the symbol you want to edit is not in the graphic page, you can scan the pages of the menu with the number keys 1-8. When you press on 1, you will see what is on page 1. If the symbol you want to edit is on the page, select it with the mouse. The second time you will use the selection box is to save the symbol you are editing. Just click on the selection box and your symbol will be automatically saved in the symbol library. 25 Powercad User Manual 9.1.1.7. Line Type When you have lines in the symbol, you can change their types. SYMBOL gives you nine line types to choose from. To change a type of line: 1. click on the line type you want, 2. click on the line you want to change, 3. when you have finished, cancel with the mouse. You can only change the type of lines. You can't change circles, arcs or arrows. 9.1.1.8. Base Point and Connection Points Base point and connection points are the most important part of a symbol. They give information to PowerCAD about where and how the component must be drawn and to the ROUTER about where the lines must connect. Each symbol has a base point and it can't have more than one. The base point tells PowerCAD where to insert the component in the schematic. When you insert a new component or you move one on the drawing, it is the base point who tells PowerCAD where to draw the component in the drawing. If you want to move the base point of the symbol: 1. click on BASE POINT, 2. click on the symbol where you want to put the base point. A symbol can have up to 50 connection points. Connections points are used by the ROUTER to connect lines between components. You must assign a type to a connection point. Types are: * power (pwr), * fluid control (plt), * electrical (ele). If you don't assign connection points to a component, it will be impossible to connect lines to it. If you want to assign a connection point to a symbol: 1. click on the kind of connection point you want, 2. click on the symbol where you want to put the connection point, 3. when you have finished, cancel with the mouse 26 Powercad User Manual 9.1.1.9. Delete This command will cause the selected object to be deleted from the symbol. To delete an object : Be sure of what you are doing, because there is no UNDO command. 1. select DELETE in the menu, 2. go onto the object you want to delete and click the mouse, 3. go onto another object you want to delete or cancel with the mouse. 9.1.1.10. Quit When you have finished designing with SYMBOL, select QUIT in the menu. When you quit, SYMBOL will update the symbol library, so it is important to leave the editor by the QUIT command. 9.2. Importing DXF Files If you want to import a symbol you made with AutoCAD, or any other CAD, you must save it with the DXF function of the CAD. Try to limit the dimension of the symbol to 2 drawing units. When you are in SYMBOL, press on [F10] and select the name of the file in the file selector. 9.3. Using Custom Symbols SYMBOL gives you a lot of power, you can design your own symbols and add it to your schematics. If you don't like a symbol in your drawings, you can change its representation with the SYMBOL editor and it will be updated in all your schematics and blocks. If you combine the custom symbols capacity with the block features you will see a noticeable increase in your productivity. It is very important that everybody, who uses PowerCAD, uses the same custom library. If you don't, you will not be able to share your drawings. The custom library is part of the schematics you make, if you send your drawings to others, and you use custom symbols in drawings, you must also send your library : "PIECEA.HYD" and "PIECEB.HYD". If you don't, it will be impossible to regenerate the schematics. 27 Powercad User Manual As powerful as the software is, we recommend that you make a backup copy of your library before you make any changes on custom symbols. The name of the files you must backup up are "PIECEA.HYD" and "PIECEB.HYD". 28 Powercad User Manual 10. Printing Printing drawings is very important. PowerCAD gives you the opportunity to print drawings and documentations that goes with them. The drawing documentations are: * Parts List, * Purchase Order List. 10.1. Choosing a Printer PowerCAD support 3 kinds of printer; 9 pins, 24 pins and HP LASERJET. If you have a 9 pins or 24 pins, it must be in EPSON or IBM PROPRINTER emulation. PowerCAD default printer operation is on 9 pin printer. If you want to use PowerCAD with another kind of printer you must add a software switch when you call it. If you are using a 24 pins printer start PowerCAD with this line : POWERCAD P:24 If you are using a laser printer start PowerCAD with this line : POWERCAD P:L 10.2. Printing a Drawing To print a drawing: 1. put what you want to print on the screen (with the zoom commands), 2. select PRINT in the menu, 3. fill the dialog box with the informations of the drawing (at PART LIST enter N).
