AutoLISP Routines

Name: CHG Description: 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.

CASEMENT draws a casement window in plan — the frame, the sash and the hinge side — from a width, a height and which way it opens. It is described in its own header as a sample program, and that is the right way to think about it: a working demonstration of parametric window drawing rather than a finished office tool. It draws from the last point, not from a … [Read more...] about CASEMENT LISP: Draw a Casement Window in AutoCAD

Name: CALC Description: A drawing of a calculator pops up. You pick it's buttons, or use the keyboard, for input. Numbers are displayed and evaluated just like a real calculator. It supports +, -, *, /, ^ (exponent), order of operations and brackets.

Four routines for the openings in a wall: two door types and two window types, each drawn parametrically from a width you type rather than inserted as a block. They are credited to Tom Stoeckel. The appeal of a parametric opening over a block library is that there is no library to maintain. A block set needs a symbol for every width you use; these draw whatever width you ask … [Read more...] about Building LISP Collection: Doors and Windows for AutoCAD

BreakPoint splits an object at a single point without removing anything. Type BP, pick the object, pick the point, and what was one line is now two lines meeting at that spot. AutoCAD can already do this. The BREAK command has a First point option, and picking the same point twice breaks at zero length rather than cutting a gap. The trouble is the keystrokes: BREAK, select, F, … [Read more...] about BreakPoint LISP: Break an AutoCAD Object at One Point

Name: Break objects around text Description: 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.
