Text on a drawing has to be sized for the plot, not for the model. Write 2.5 high text on a plan you intend to plot at 1:100 and it comes out at a fortieth of a millimetre on paper. The arithmetic is not hard — plotted height times scale factor — but doing it in your head every time you change scale is how drawings end up with four different text sizes on … [Read more...] about TEXTSIZE LISP: Work Out AutoCAD Text Height from Scale
TXP LISP Routine: Explode AutoCAD Text to Polylines
TXP is a free routine for AutoCAD that explodes single-line TEXT entities into polylines. Its author, Ken, describes it as eliminating font garbage and overlapping or duplicate lines, and outputting clean open and closed polylines rather than a loose pile of segments: it eliminates font garbage and overlapping or duplicate lines, and outputs clean open and closed polylines … [Read more...] about TXP LISP Routine: Explode AutoCAD Text to Polylines
TRUSS LISP: Parametric Floor Truss Elevations for AutoCAD
TRUSS draws elevations of open-web floor trusses — the parallel-chord trusses used in timber floor framing, with a web of diagonals between top and bottom chords. You give it the truss depth, the size of the chord and web members, and the web spacing, and it draws the elevation. Drawing one of these by hand is tedious and drawing several at different depths is worse, … [Read more...] about TRUSS LISP: Parametric Floor Truss Elevations for AutoCAD
