New User here - I’d like to extrude a curve / surface from both sides simultaneously. Is this a feature?

The simple answer is Yes.

Select both faces and extrude as normal.  
Both surfaces will extrude simultaneously in their respective directions…

And naturally, the same applies to any flat surfaces.  
Select the faces you wish to extrude and extrude them all simultaneously…

Hope this helps 🙂

Thank You for the videos they are great! But, if I am starting from a single surface/plane in order to get to the 3D solid to start with I can’t seem to get it to behave the same way. It will only extrude in a single direction - or am I am missing something with the surface?

Aha. I see. Unfortunately, a plane can only be extruded in one direction.
