Still using ACAD2002...should be getting ACAD2007....probably in 2009
Here's my next lame attempt to modify a lisp file.
This routine asks the user to select a part, select any holes, oblongs, or cutouts, and provide the gauge used for the metal blank. The routine does all the math and posts the results to the command line in the form of area, laser (perimeter), and weight.
Been working great until I got ahold of it.
Now that we have begun to cut text (polylines... not real text or font) into our parts, I've been asked to modify this file to allow the user to make an additional selection for the laser-cut-text which would then be added to perimeter value with no change to area.
It worked fine until I got ahold of it.
Here's the error message I get:
Select objects:

My major changes fall between the ";-----------------------"
