Shoe Base to Solid

Hi,

I was able to project my desired show base onto a curve.
I extruded it into a surface as shown.

However, I can’t seem to make it into a solid.

If anyone has any tips it would be greatly appreciated!

Thank you!

Check the curves before making a solid. The curves must be closed.

You are awesome! Youtube is my savior but its sometimes hard to pin point which exact video to watch and you end up going down a completely different rabbit hole! This helped a lot! I just did it the old fashioned way with the split command by adding surfaces on the top and bottom manually.
