-
- PrintCADD 3-D is a three dimensional computer aided drafting,
- design and modelling software. It requires approximately 540K of
- free RAM memory as well as an EGA or VGA video card. It also
- requires at least 300K of free disk space after installation. There
- are other versions that require less free RAM.
-
- The software comes in 4 files, 3 of which are self extracting
- archive files. The other file is this file, README.DOC. The
- archive filenames and the files that extract from them are listed
- below.
-
-
- PRCAD1.EXE - This file contains the program file as well as
- several support files that allow the user to run a
- minimally configured system. However, the online
- help and tutor system will not operate unless the
- files located in PRCHELP.EXE are also extracted.
- This file is the generally available "Shareware"
- version of the product.
-
- Extracts to:
-
- PRCAD1.EXE - This is the main executable program file. It is
- approximately 475,000 bytes long, once extracted.
-
- *.FNT - There are four pre-made fonts available in PrintCADD
- 3-D. All fonts use the extension, ".FNT".
-
- *.PRD - These files are printer drivers. Read the manual or
- help system to decide which ones will work with your
- printer. Each of these files is 86 bytes long.
-
- *.PLD - These files are plotter drivers. Each one of these
- files is 73 bytes long.
-
-
- HELP.EXE - This self extracting archive file contains all the
- files associated with PrintCADD 3-D's help and tutor
- systems. These files are required for the tutor and
- help systems to operate. This file also contains
- the manual for PrintCADD 3-D.
-
- Extracts to:
-
- PRCAD.TUT - This file contains the lesson material associated
- with the tutor system. It is 209,739 bytes long
- once extracted.
-
- TUTOR*.GVF - These files contain the PrintCADD 3-D drawing files
- that are used in the lessons. They total to
- approximately 64,000 bytes in length.
-
- TUTOR*.LYR - These files contain layer information associated
- with the tutor drawing files. They total to about
- 600 bytes in length.
-
- PRCAD.MAN - This ASCII text file contains a manual that explains
- all of the menus and functions in PrintCADD 3-D. It
- is 241,922 bytes in length. This amounts to
- approximately 110 pages of 8.5 x 11" paper.
-
- PRCAD.HLP - This file contains information used by the help
- system. It is 209,739 bytes long once extracted.
-
-
- SAMPLE.EXE - This self extarcting file contains sample drawing files,
- These files, while not necessary, demonstrate several
- important aspects of PrintCADD 3-D.
-
- Extracts to:
-
- *.GVF - These files are sample drawing files. Some of these
- files contain pictures that are referred to in the
- manual file. They total approximately 242,000 bytes
- in length.
-
- *.LYR - These files contain layer information associated
- with the previous drawing files. These files total
- approximately 800 bytes in length.
-
- *.SRF - These files are part files. They total approximately
- 7300 bytes.
-
- * Other Versions *
-
- BirdsEye Enterprises automatically includes 8 different versions
- of PrintCADD 3-D in the package sent to registered users. Each
- version is optimized to perform better with certain types of computer
- hardware and/or software. Each of these versions includes the files
- found in PRCAD1.EXE. Shareware versions of these files may also be
- obtained directly from Birdseye Enterprises for a fee of $12.50 U.S..
-
- The name of the extraction file and it's optimization(s) are listed
- below:
-
-
- PRCNONE.EXE - This version of PrintCADD 3-D contains no
- optimizations other than the removal of the
- registration reminder screen.
-
- PRCEX.EXE - This version of PrintCADD 3-D has been optimised to
- run on computers that use L.I.M. 4.0 expanded
- memory. The main advantage to using expanded memory
- is that PrintCADD 3-D can move part of it's
- executable code into this memory. This in turn
- allows more standard memory to be available for TSRs
- and operational environments such as Windows 3.0
- etc. One other advantage is that {Grup} commands
- will be able to use much larger selections sets
- because there will be more available memory.
-
- PRC87.EXE - This version of PrintCADD 3-D has been optimised to
- take advantage of a math co-processor. Many
- operations will run quicker and more accurately.
- (This may actually make the program run slower on
- some 286 and above systems because their math executes
- much faster than older 8088-86 systems). It will
- also use less main memory.
-
- PRCEX87.EXE - This version of PrintCADD 3-D is optimised to take
- advantage of a math coprocessor and expanded memory.
-
- PRC286.EXE - This version takes advantage of the instruction sets
- found on 80286, 80386 and 80486 computers to
- increase the speed of certain operations as well as
- to use slightly less main memory (approximately
- 17K).
-
- PRC286EX.EXE - This version takes advantage of the 80286-80486
- instruction sets as well as expanded memory.
-
- PRC28687.EXE - This version takes advantage of the 80286-80486
- instruction sets as well as math co-processor.
-
- PRCALL.EXE - This version takes advantage of 80286-80486
- instruction sets, math co-processor and expanded
- memory.
-
- To perform the installation:
-
- 1) Make a directory to contain the PrintCADD 3-D files.
- eg. MD prcad "Enter"
-
- 2) Copy the Help.exe, Sample.exe and one of the aforementioned
- versions of PrintCADD 3-D into the directory.
- eg. Copy a:help.exe c:\prcad\
- Copy a:sample.exe c:\prcad\
- Copy a:prcad1.exe c:\prcad\
-
- 3) Make the directory that was created the current directory.
- eg. CD c:\prcad "Enter"
-
- 4) Type the name of each extraction file (without the .EXE).
- eg. prcad1 "Enter"
- help "Enter"
- sample "Enter"
-
- 5) Delete the original extraction files.
- eg. del prcad1.exe "Enter"
- del help.exe "Enter"
- del sample.exe "Enter"
-
- The files contained in the extraction file will be unpacked
- into the directory. If files, with the same names, from previous
- versions already exist in the directory, the software will prompt
- the user as to whether they wish to overwrite the old files. In
- most cases the user should respond with "Y" for yes, however, if
- the user has modified a sample drawing, plot driver, print driver
- or similar file, they may wish to save the old file and should
- respond "N" for no.
-
- The following table shows the files that are required:
-
- PRCAD.EXE - Program file * required
- PRCAD.HLP - Help file * required for help
- PRCAD.TUT - Tutor file * required for tutor
- TUTOR*.GVF - Tutor graphics files * required for tutor
-
- At least one of the following font files is required for text and
- dimensioning or the user must create their own:
-
- STANDARD.FNT - Font file
- FAST.FNT - Font file
- PICA.FNT - Font file
- BOLD.FNT - Font file
-
- The software will also contain the following files:
-
- PRCAD.MAN - PrintCADD 3-D manual in ASCII format
- *.SRF - Surface part files
- *.PRD - Printer driver files * required for printing
- *.PLD - Plotter driver files * required for plotting
-
- The system also generates several other types of files while
- running.
-
- *.GVF - Drawing files
- *.PFL - Printfiles
- *.HPG - Plotfiles
- PRCAD.DEF - User default file
- PAG*.2DF - System redraw files * You may delete these
-
-
- 4) Make the installation directory the current directory and
- delete the "PRCAD.DEF" file if it exists. This file holds
- configuration data that may not be usable by the newer version
- of PrintCADD 3-D. In most instances the software will report an
- error #5 or #7 if this file is invalid.
-
- 5) Type "prcad". The software will then prompt the user to select
- the appropriate video driver and install the program.
-
- After the software is installed, the user should invoke the "tutor"
- or examine the "help" system in order to get a feel for the system
- before using it. Even users that have used other three dimensional
- drafting systems should examine the section on creating files. The
- help may be invoked at any time by pressing the "F1" key, the tutor
- by pressing "F2".
-
- Version 1.05 of PrintCADD contains a new hidden line feature as
- well as a more streamlined interface. This feature is selected
- through the {QuikHide} and {Hideline} commands as documented in the
- manual and help systems but another intermediate menu will appear
- that allows the user to select one of <CenterSort>, <DepthSort>,
- <TrueSort> and <FindCenter>.
-
-
- The <CenterSort> option is the same as the previous versions and
- sorts the surfaces by the distance to the centers of the surfaces.
-
- The <DepthSort> option sorts the surfaces by their greatest depths.
-
- The <TrueSort> option uses a considerably better although much
- slower sort for sorting the surfaces. This sort works very well
- for parallel projections. In perspective projections the user must
- make sure that the vanishing point is on the sides of the objects
- that are exposed by the angle of the view. That is, if the user
- can see the front and left of the building, then the vanishing
- point should be to the left and in front of the building before the
- proper view will be shown. In either case, intersecting surfaces
- will not be shown properly and neither will three or more surfaces
- that are interlocked alternately behind one surface and in front of
- another surface to form a triangle, rectangle , circle etc. Such
- arrangements require that one of the surfaces must be broken into
- two separate surfaces before rendering properly.
-
- The <FindCenter> = (Yes|No) option sets the system so that it will
- attempt to find a new center point for all portions of a surface
- whose center point has been clipped from view. Care must be taken,
- with concave surfaces, that no portion of a straight line, drawn
- from the center point of a surface to any point on the edge, will
- fall outside the surface or this option will not work correctly. If
- necessary, move the center point or break the concave surface into
- two or more surfaces.
-
- The previous options also appear when the user selects <Continuous>
- from the {PrintFile} <Create> menus. They allow the user to create
- unattended hidden line print plots (PrintFiles).
-
- Many of the regeneration prompts have been eliminated and the
- regenerations work the same in both the perspective and parallel
- projection modes.
-
- The {AbsRelDbas} and {Aperture} commands have been added to the
- [Draw] menu to allow more flexibility while selecting points.
- These commands are identical to the commands documented in the
- {Vars} menu section of the help system and manual.
-
- A {CursorSize} command has been added to the {Vars} menu, allowing
- users to control the size of the cursor independently of the size
- of the aperture distance.
-
-
- Version 1.06 incorporates the following changes:
-
- The {Directry} command has been modified to allow more control over
- where files are stored by PrintCADD 3-D.
-
- The [System]{Colors} command has been modified to allow more
- control of menu colors.
-
-
- Version 1.07 incorporates the following changes:
-
- A {ucstoSurf} command has been incorporated into the {Ucs} menu to
- allow additional flexibility when setting up user coordinate
- systems. The user may now select a line segment that will act as
- the X axis. The UCS will then aline itself so that it falls on the
- surface that the line segment belongs to.
-
- The [Draw]{ucsAline} and {Cad/cam}{Vars}{auToaline} commands now
- feature an option that automatically realines the cursor with the
- UCS spacing grid at the beginning of each point selection.
-
- The {Cad/cam}{Vars}{Groupsize} command allows the user to control
- the maximum size of groups used by the {Grup} and {Aim} commands.
-
-
- Version 1.08 incorporates the following changes:
-
- The F3 and F4 keys are used to record and play back macros. The F3
- key also allows the user to introduce timing sequences into the play
- back of macros. Macros can be recorded or played back at any time.
-
- Better error trapping for parts, dimensioning and text commands.
-
- Version 1.09 incorporates the following changes:
-
- Documentation was changed to reflect ASP membership.
-
- Better hidden line elimination on cutaway views.
-
- Better cursor centering in perspective viewing modes - the cursor
- will be placed at a point in front of the view point if it was
- behind the view point previously.
-
- Eliminated a problem with hidden line viewing and snaps on drawings
- that exceeded approximately 13000 elements.
-
- Better centering on {Zoom}{Out zoom} command.
-
- The {Dims}{Alined} command with no witness lines alines properly to
- current UCS.
-
- More convenient memory allocation and deallocation for {Vars}
- {Grupsize} and {Rdrw}{Quickhide} routines.
-
- On disk manual now includes page numbers and index.
-
- Note!:
- Due to new features incorporated in this release, previously
- created, perspective viewing windows may have to be readjusted so
- that drawings do not appear as cutaway views or dissapear altogether.
- Simply change the window to parallel viewing mode and then set up the
- perspective view again.
