3D Shapes Introduction

This chapter covers all the 3D shape creation commands available in GDL, from the most basic ones to the generation of complex shapes from polylines.

NURBS Primitive Elements

Compatibility: NURBS related commands and functionalities introduced in ARCHICAD 20. The primitives of 3D data structure of NURBS bodies are: NURBSCURVE2D NURBSCURVE3D NURBSSURFACE NURBSVERT NURBSEDGE NURBSTRIM NURBSTRIMSINGULAR NURBSFACE NURBSLUMP NURBSBODY Solid NURBS bodies are represented by the boundary NURBS faces of the solid region(s), laminar surface NURBS bodies are represented…
