- Re: New PD1:<MSDOS.AUTOCAD> Uploads
-
- I've uploaded the following files to SIMTEL20:
-
- <msdos.autocad>
- RECT.ARC AutoLISP: Rectangle drawing routines
- SFILL.ARC AutoLISP: Fill between 2 Arcs, Lines, Plines
- PDIST.ARC AutoLISP: Finds dist betwn two pts on pline
- PARNCH.ARC AutoLISP parentheses checker/ pretty printer
- DTL.ARC AutoLISP: Extracts detail section of drawing
- ANSIMENU.ARC AutoLISP: ANSI menu system for developers
- SV-ENV.ARC AutoLISP: Saves AutoLISP environment to file
- DRAGON.ARC AutoLISP: Generates recursively defined dwgs
- CHG.ARC AutoLISP: Low level entity access
- DOOR.ARC AutoLISP: Two pick door program
-
-
- These files replace the file ACADARC.ARC now in the <msdos.autocad>
- directory. Most of these files are AutoLISP code, for use with
- AutoCad's imbedded LISP interpreter. Although they're uploaded for
- the MSDOS section, they should work with Unix AutoCad or MacIntosh
- AutoCad as well. The one exception is MENU.LSP which uses the DOS
- specific ANSI.SYS device.
-
- I hope they're useful. Feedback is welcome.

- Detailed descriptions of the uploads follow:
- --------
- RECT.ARC AutoLISP: Rectangle drawing routines
-
- RECT.LSP
- RECT draws a rectangle based on digitizing the lower left corner and
- supplying X and Y dimensions. The widths and rounding radius can either
- digitized or entered in dimension format from the keyboard.
-
- REC draws a rectangle based on digitizing two corners and prompts for
- the corner rounding radius. The rounding radius can be digitized.
- The default rounding radius is always 0.

-
- SFILL.ARC AutoLISP: Fill between 2 Arcs, Lines, Plines
-
- SFILL.LSP
- SFILL will construct an even division of SOLIDs between any 2 Arcs,
- Lines or Polylines on any elevation plane.
-
- This routine was once RULESURF.lsp and much of the code was designed
- to collect and use 3dpoints for 3dfaces. It works well with the SOLID
- entity and I think you will find it very useful. Please feel free
- to modify and improve this code.
-
- Note: the entities must "read" in the same direction, else you will
- get a major bow tie effect.

-
- PDIST.ARC AutoLISP: Finds dist betwn two pts on pline
-
- PDIST.LSP is a AutoLISP 2.6-based user defined command that measures
- the distance between two points along a polyline. This is accomplished
- by BREAKING out the polyline segment to be measured, using the
- AutoLISP 2.6 AREA command to report the length of the polyline,
- and using the UNDO command to repair the break.
- By Philip M. Kreiker, Looking Glass Microproducts
-
- PARNCH.ARC AutoLISP parentheses checker/ pretty printer
-
- Program for AutoCAD users who need to "clean-up" a Lisp source file
- similiar to "Pretty-Type" and do Parentheses checking at the function
- level.
-
- This routine will not only check each function and report on missing open
- and closed parentheses but it will also create a file, [filename.CNG], that is
- indented at each parenthesis level. This file allows easy traceback of the
- parentheses levels of the routine, it can also be the final source file.
- Usage: Type PARNCH at the DOS command prompt.

-
- DTL.ARC AutoLISP: Extracts detail section of drawing
-
- DTL.LSP
- Extracts a section of a drawing for a detail.
- Lines, Arcs, & Circles are trimmed to the box boundary.
- P-LINES and equal scale blocks are exploded one level in the detail
- before trimming.
- By Robert McNeel & Assoc. 1310 Ward St., Seattle, WA, 98109
-
- ANSIMENU.ARC AutoLISP: ANSI menu system for developers
-
- MENU.LSP
- The function MENU-OPERATION creates menus in text screen mode for AutoLISP.
- It assumes an 80 column textscreen monitor and ANSI.SYS graphics device
- MENU-OPERATION looks for and returns an integer.
-
- In this version, the header, prompt and individual items in the item-list
- MUST all be strings.
- The syntax is:
- (menu-operation "header" '("item-1" "item-2" ... "item-n") "prompt")
- By Ben Olasov, Graphic Systems, Inc., Cambridge, MA
-
- SV-ENV.ARC AutoLISP: Saves AutoLISP environment to file
-
- Environment writing function for *Release 9*. Flaky in Release 10.
- This function C:SV-ENV saves the current LISP environment into a file with
- the name of the drawing and with the extension .LSP. For example, if the
- name of the current drawing whose LISP environment you wish to save is
- FOOBAR.DWG, then the name of the LISP file to which the environment is saved
- will be FOOBAR.LSP.
-
- For this function to work at all, you must have placed a marker in your
- ATOMLIST (AutoLISP's record of all LISP variables, functions, etc.).
- To do this, simply place the following line at the end of your ACAD.LSP file:
- (setq MARK 'T)
-
- Then the SV-ENV function will not attempt to record AutoLISP's primitive
- functions, or the functions automatically loaded with your ACAD.LSP.
-
- To restore your previous environment of variables and user functions, just
- type (load "dwgname") at the command prompt, where "dwgname" is the name
- of the drawing whose LISP environment you saved.

-
- DRAGON.ARC AutoLISP: Generates recursively defined dwgs
-
- DRAGON.LSP
- From _LISP_ by Patrick H. Winston and B. K. P. Horn, published by
- Addison/ Wesley. Contains command level functions C:DRAGON, C:C-CURVE
- and C:DEMO.
- By Ben Olasov, Graphic Systems, Inc., Cambridge, MA
-
- CHG.ARC AutoLISP: low level entity access
-
- CHG.LSP
- CHG displays and modifies the properties of individual entities.
- CHG creates a numbered menu of the selected entities properties, and
- then prompts the user to select the number of the property to modify.
- CHG then prompts for a new value for that property, which may be a
- point (list), real, integer, or string.
-
- Any changes made by CHG can be undone using AutoCad's 'U' command.
- Doing so will return the drawing to its state before using CHG.
-
- An example use of CHG:
- In a drawing containing two valid blocks A and B, an individual
- iteration of block A can be transformed to an iteration of block B by
- giving B as its new name. All of its previous insertion parameters will
- remain the same, but its identity will be changed to block B. If the
- name of the layer in which the entity resides is changed to the name of
- an existing layer, the entity will change its residence to that layer.
- However, if the new layer name is the name of a non-existing layer, a
- layer with that name will be created, and the entity will be transferred
- to that layer.

-
- DOOR.ARC AutoLISP: Two pick door program
-
- DOOR.LSP contains the command level function C:DOOR which prompts for
- the hinge point of the door, then the swing point, and proceeds to break
- the wall, finish the door opening, and draw a door symbol scaled to the
- size of the opening.
