Trying to make 4 triangles and 4 trapeziums, such that they form the shapes made by the construction axes, very new here, any help would be great.
I think you should subtract from the octo prism .
Like this:
Hi, that looks promising, is there a video with sound so I can understand how to apply that to my problem?
Sorry , no sound.
You should make construction planes on both sides and poroject all edges to the plane.
In that case you can edit your scetch on it .
That’s really helpful, thanks you
If you need thickness of the body like on your example, tap on the octogon face , then use the shell comand
