[CIG-LONG] Model with gravity

[Tariqul Islam]

Hi Walter,Thanks for reply. If I do not use WallVC how can I work out to extend the model when the base is angular and sliding down by gravity. The other question is I am using Gale 1.5 and tried to build 3D model but did not work. Do you have any suggestion?
Kind regards Tariq
