Modeling a Volume
"Separate" a surface (s) from a volume and "Add points" (Menu Edit / Add Pts)

This is like a deformation cage where you only have to move the Control Points!
The addition of Points can only be done on an individual surface!
On the other hand, you can then move Control Points from several surfaces in the same time!
Edit / See Points function enabled of course! You can use the Edit / Hide and Lock functions for help!
At the end, everything is grouped in a single "solid" volume (if the points of each side are "welded"!




For "Bring closer and distance Point(s)" simple use the Transform / Scale Function !
