Hi, I am trying to make a small crown shaped playing piece for a game.
I have constructed a cylinder, and a shape that is 4 triangular prisms joined together that I hope to use to cut away the spiky top edges of the crown.
I can’t seem to use the subtract tool because it complains about not being a solid.
I thought maybe the issue might be that I have not properly combined the triangular prisms, I tried Union but had similar issues with a warning message. I’ve tried cutting away internal lines but it quickly gets very messy and unmanageable.
Can anyone help, or suggest a better approach?
