LISP Routines

Routine creates a text entity that specifies the distance (length) and bearing (angle) of a select line or pline segment.  Used in surveying and map making.

Routine to join 2 polylines together.  User is prompted to select 2 plines, which are joined by drawing a line between the ends closest to the pick point, then joining them with the PEDIT command.  The first pline picked controls the layer, color, ltype, etc.

These are just a few of the top lisp routines you should check out in the library; HFACE.lsp -Create 3dfaces to hide entities around text, Enedit.lsp-Create a selection set quickly and easily, then take advantage of its powerful editing routines. Var.lsp -Creates a text file that records all the settings in the current drawing. When the restore button is pressed var.lsp quickly restores those saved settings. Spurge.lsp-purge command without verifying every purge. Brktxt.lsp-Break a line of text and either add it to another line or create a new line of text with it. Gpedit.lsp-Edit a polylines globally. Asview.lsp-View a text file and print it from Autocad. Clean.lsp -Finds all null text and text containing only
spaces in your drawing so you can easily get
rid of them.

Another grab bag of useful lisp utilities that includes Breakf.lsp -is a utility that allows the user to pick a line, polyline or an arc and break it at a specified point by only picking the location once rather than 2 times, like the Autocad version Break/F. Flayer.lsp - A utility that allows a user to Freeze, Delete, Turn off or make current the layer of a selected entity. Iang.lsp - A utility that calculates the angle between 2 intersecting lines by allowing the user to pick the lines. Lay.lsp - a utility that allows the user to save or restore a list of layers to a drawing. Mtrim.lsp - a list routine that allows the user to trim multiple entities with on pick. Stamp.lsp - A utility that places a stamp it a specified location that contains the user name, the modification date and time and the drawing name. Sum.lsp - a utility that allows the user to add a list of numeric text strings contained in a drawing and place the total at a specified location on the screen.

Program to process layers quickly based on object selection.

This program will take any file and encrypt it so that ONLY AutoLISP can read
the contents. The encryption is based on a user supplied encryption key. This
can be any single ASCII character.

This program file allows the user to drop in a pitch triangle representing base and rise of a sloping line segment, i.e. 12:7 pitch.

Program to process of several polylines simultaneously. The user can select a group of entities, the program will filter out non-polylines. The user is then prompted to select one of the following properties to be manipulated; Width - change all selected plines to the specified width, Elev - change all selected plines to the specified elev, Layer - change all selected plines to the specified layer, Area - calculate the total area of the selected plines, Color - change all selected plines to the specified color (use -1 for BYLAYER), 2d - convert 3D plines to 2D plines (all 2D & 3D plines are set to 0 elev), 3d - convert 2D plines to 3D plines (existing 3D plines are unaffected), ? - displays this help screen

This package was put together primarily as an aid to the sheet metal turret programmer although it has been found very useful by inspectors, quoters and designers of sheet metal parts and tooling. It is assumed that the reader is familiar with sheet metal layout theory.The forming calculations in this software are based on Lockheed formulas. Shop practice varies but these formulas are the most widely used. For those of you who use a set back (or K-factor) chart there is a routine on the main menu to adjust for this.

Use this tool to draw bent steel stair pans.  There are options to fill pans with concrete and for detailing purposes there is an option for auto-dimensioning.

Contains 4 lisp routines including: Box1.lsp - Pick an insertion point and then your cursor will drag from the center of the box asking for a point. You can enter as any points as you wish and a line will be drawn from point to point. After you have picked your last point, enter a return. If you wish, you can also insert the box and strike enter for no extension line. Delta1.lsp - This is the same as Box1.lsp except that it inserts a delta (triangle). Note.lsp - This is the same as Box1.lsp except that it inserts a circle.

This routine writes a text string to the drawing and then breaks any lines, polylines, etc. that intersect an imaginary box around the text. The text is placed on the current layer using the current style. The default input and repeat capabilities of TB.LSP make multiple labeling very convenient.

A block cataloging and retrieval system that works within AutoCAD. It works similar to the WBLOCK command, but places all wblocks into an icon menu automatically. The wblock (symbol) can then be picked visually from the icon menu and inserted into any drawing, using multiple options for insertion scale, angle, etc.

This utility draws graphs of trigonometric functions that can be expressed in the form: "y = <function> of x". The routine permits virtually unlimited graph range by calculating and writing graph points to a file on disk, then reading the file to produce the graph. The disk file is named "gfpts.txt."; edit TGRAPH.LSP and change this name if it conflicts with a file name of your own.

An AutoLISP program for surveyors and civil engineers for traverse note reduction.

The first command, SCB, will erase and trim all entities outside of the rectangle and leave a polyline border. The second command, SC, will erase and trim all entities outside of the rectangle but will not leave a border. The final command, SCD, will erase and trim all entities inside of the rectangle and will not leave a border.

This file contains 2 block updating lisps; Updblkly.lsp - This routine allows the user to update the layer of all entities within a block to a single layer (exam: layer=0) without the user having to explode the symbol. By default the color of all entities are changed to BYLAYER. The routine changes the original definition of the block within the current drawing.Updblkcl.lsp - This routine allows the user to update the color of all entities within a block to a single color (exam: color=BYLAYER) without the user having to explode the symbol. By default the layer name of all entities are NOT changed. The routine changes the original definition of the block within the current drawing.
