Merge 2D irregular shapes to generate 3D solid I have 2 SVG shapes. Consider them as top and bottom faces of an object. I want to 'blend' one shape to the other to create a 3D solid. They have a differing number of vertices. Am I able to do this in Blender? I have limited understanding of Blender, but from viewing various YouTube videos it strikes me that what I am attempting should be relatively straight forward?

If anyone can point me to a tutorial I'm happy to give it a go.

Thanks, Darren.



Tried the suggestion below and got this:
Are the shapes too complex (hard to believe), note number of vertices? I get the feeling there should be some control vertices that would avoid the cross-over effect?
Join both objects together (Ctrl+J) if not joined.
In Edit mode select outer edges of upper and lower parts, hit Ctrl+E and select Bridge Edge Loop
