Help: vert {2}, edge, vect, pgon, how are these commands used?
Constructing a freeform surface definitely requires these instructions.
Unfortunately, I have tried many times but still cannot find their patterns.

Hello yongler.

In GDL manual You find Primitive elements in pages 137-149 (AC 26 manual).

After studying these You may have new  spesific questions.

[yongler]

After two days of contemplation and experimentation, I seem to have learned some about how VECT, EDGE, and PGON operate.

Primitive elements can control the material representation of each unit of the surface, thereby expressing the analysis of mountain elevation, slope, etc. The GDL script is still being further optimized.
