CUSTOM PATTERN MAKER'S
Custom Pattern Maker's special
pattern drafting "macros" are written in LISP.
When the development of CPM began in 1985 the programming language used
in AutoCAD® was LISP. At that time LISP was considered to be an
easy to learn and powerful programming language.
The pattern drafting functions, special arch functions "xarc" and "harc", and the custom SEW
MENU are written in LISP by programmer Jim Pickrell
and Stephanie Schoelzel. Jim brilliantly developed
arcing functions that created the needed parabolic eclipses common to necklines, armholes, crotches,
hiplines and hems.
With the edition of AutoCAD® version 13, AutoDESK made the choice
to completely rewrite all their code based on new code. This change
was essential to AutoCAD®'s ability to continue as a powerful application
in the light of new technological advances. However, for CPM , all the
code had to be rewritten. This task has finally been accomplished. With
version 14, the user interface had to be completely redone also.
Currently CPM will run :
- As a stand-alone software on Windows
95 & 98.
- As an AutoCAD® add-on with
Windows 95 & 98 and AutoCAD 13 & 14
- And as an AutoCAD® add-on
- Macintosh AutoCAD® version
12 on pre-Power Macs only
- Macintosh G3s using VirtualPC
software and with AutoCAD® for DOS or Windows versions 10 through 12 Windows3.1. and Windows
95 with AutoCAD® 13 & 14
- DOS & Windows 3.1 with AutoCAD®
for DOS or Windows versions 10 through 12
- Windows95 with AutoCAD® for
DOS version 12
