Name: WIN Description: This routine draws windows with multiple mullions in plan view between any two lines at any angle, without the use of a block. It works best if the lines are parallel, but is not required. The routine will place the mullions and glass on the current layer, and it will place the wall jambs on the same layer as the walls. I have included two functions. One … [Read more...] about Windows with Multiple Mullions Lisp Routine

WBLKALL writes every block definition in the current drawing out to its own DWG file in one pass. Instead of running WBLOCK once per block and typing each name, you run one command and walk away. It was written in 1993 by Chris Bryant, and for a file this old it is unusually tidy code: it declares its local variables, saves the EXPERT system variable before changing it and puts … [Read more...] about WBLKALL LISP: Export Every AutoCAD Block to Its Own DWG

WALLSECT constructs an exterior wall section — the vertical slice through a wall that goes on nearly every set of architectural drawings. It is somebody's first program. The header says so, in the author's own words: "Not bad for my first shot at LISP programs!!!" She was Brigitte Robertson, a student at Billings Vocational Technical Center in Montana, and she wrote it … [Read more...] about WALLSECT LISP: A 1994 Student Wall Section Routine

WALLS is a nine-command wall drafting package for AutoCAD floor plans, credited to Alacrity and now at its third revision, version 1.3. It gives you four different ways to draw parallel-line walls, a cleanup routine for the junctions, and commands for openings, doors and windows. The documentation is a proper reference manual with worked examples, which for a package of this … [Read more...] about WALLS LISP for AutoCAD: Nine Wall Drafting Commands

Three small editing commands in one file, each changing one property of one object you pick. Between them they cover the three edits that come up most often when tidying somebody else's drawing: the content of a piece of text, how wide that text is squeezed, and the colour of an object. They are by Ade Suharna, dated 1 September 2004, and carry his own program numbering along … [Read more...] about MET, WF and EOC: Three Small AutoCAD Edit Commands

VPTEXT is a small free AutoLISP routine that scales selected single-line text by a viewport scale factor you type in. It comes from an era when annotative text did not exist and drafters routinely drew text in model space at its intended paper height, then had to multiply every height up to suit the viewport scale before plotting. VPTEXT does that multiplication in one pass … [Read more...] about VPTEXT LISP Routine: Scale Text to Viewport Scale in AutoCAD
