bezier curve and faces

wheni do a complex shape with bezier curve then extrude bevel and selecft the 3D
i loose all the internal faces

is there a way to keep theses faces ?

Happy blendering

could you post a screenshot?


AFAIK no 3D curve keeps faces, only 2d. You can see the effect even without extruding. Add a Bezier curve (2D), add a couple of verts, then press c to close. Now press z to go to shaded mode, and you will see that it appears as though it is a single face. Now press the 3D button, and you will see it looks like a curve, no filled faces. When you extrude, either as a 3D curve, it is like an extrusion withought end caps.

Best of Luck!
