I am very new to modelling with surfaces and I apologize if this has been greatly discussed before. But i am having a hard time diagnosing the problem.
The issue is is that when I go to thicken my surface model, I get the dreaded error of unable to thicken the surface. When I go and thicken each surface individually, there is an extruded surface that is causing the issue (it is labeled as surface-extrude8). I would find a way to thicken this individually; however, this surface needs to be knit with the other surfaces in order to perform a filled surface operation successfully.
I have been staring at this guy for hours and I could use an extra pair of eyes.
Please, any help will be greatly appreciated
