I got some issue with VW 2021 when I try to extrude some shape with curve line.
The wireframe shape stay correct, but the 3d rendering look like straight line instead of curve.
I tried with many shape and the problem is constant.
Somebody have an idea how to fix it or I wait for the next update?
Vectorworks Preferences, 3D Pane. Set the 3D Conversion Resolution to something higher. Working from memory, but I think:
Low=8 sides
Medium = 32
High=128
Very High=256
Medium or High are usually your best bet for speed/workabiliyt versus quality.
