 | | Idea for a meta-statement
|

As a part author, I would *love* to see a POLYGON meta-statement. It would allow any number of points, and could be concave or convex (but not bow-tied). This would allow part authors to (more) easily construct surfaces, because they would just need (...) (22 years ago, 26-Sep-02, to lugnet.cad.dev)

(...) Actually, if I remember right, the Minifig Modeler in LDAO uses LDLite statements for placement and rotation. Of course, it's been awhile since I was in that code, so I could be hallucinating... 0 TRANSLATE <to end of arm> 0 ROTATE <wrist into (...) (22 years ago, 26-Sep-02, to lugnet.cad.dev)

Hi Kevin, When I try to test Lsynth, my system (Win2000 french) complains that CC3250.DLL can not be found. Is it a standard component or is it specific to your program ? Philo www.philohome.com (22 years ago, 24-Sep-02, to lugnet.cad.dev)

Here is an update on formalizing synthesis. For now, I'v decided to make the synhtesizer a stand alone program that runs at a command prompt like L3P. The program is called lsynth. It takes two command parameters: source LDR name amd destination LDR (...) (22 years ago, 23-Sep-02, to lugnet.cad.dev)
