DOOR.LSP is a compact AutoLISP routine written by Ben Olasov of Graphic Systems, Inc. in 1988 and 1989. Its job is exactly what the header calls it: a two-pick door command. You pick a hinge point and a swing point on one face of a wall drawn as parallel lines, and the routine cuts the opening, draws both jambs, the open leaf and the swing arc, all on the wall's own … [Read more...] about DOOR.LSP: Two-Pick Door AutoLISP Routine for AutoCAD

DOF offsets a line to both sides at once and deletes the original. One pick and one distance turns a single centreline into a pair of parallel lines — which is how you draw a wall, a road, a duct, a channel or anything else where the line you drew is the middle of the thing rather than its edge. Doing it with AutoCAD's OFFSET command means running it twice, picking a … [Read more...] about DOF LISP: Double Offset a Line Both Ways in AutoCAD

Copy a piece of text and change the wording in one operation.

Four lines of AutoLISP that turn a line or an arc into a polyline in one step. AutoCAD can already do it — PEDIT, select the object, answer Yes to the offer to turn it into a polyline, then Enter to exit — but that is four inputs for something you may do fifty times while tidying a drawing for hatching or offsetting. This wraps the sequence so you pick the object … [Read more...] about C2P LISP: Change a Line or Arc to a Polyline in One Step

CGRID lays out a suspended ceiling grid inside a room you define, and centres it. That centring is the whole point: a ceiling grid started from a corner leaves a sliver of a tile at the far wall, whereas one centred on the room gives you matching cut tiles at both edges, which is what a ceiling is supposed to look like. It is by Harold E. Davis, version 1.0, dated 13 April … [Read more...] about CGRID LISP: Draw a Centred Ceiling Grid in AutoCAD
