Vertices from Volumes

Vikrantca

Hello, Iam generating a GAMBIT journal file from c++ code. My application requires creation of several hundred equi-spaced volumes (I use bricks in GAMBIT). After creation , I need to create a face out of the space between two bricks (there will be 4 faces that can created). My questions - (a) is there a way to access the vertices of a volume that is already created or (b) is there a way to access the edges or faces of a volume already created. I want to do this thru code.

thank you in advance. Best Regards, vikrantca
