I tried with bevel, but I can only do one side of the object. Do you have idea how to make whole object?
You could use your geometrical pattern as background blueprint, then:
- Create a circle, extrude inwards (as suggested by the other answers, the Spin or Screw tools might be more convenient ways to create the initial shape):
- Only keep a segment and delete its inner faces:
- Extrude upwards, don't forget to recalculate the normals:
- Give it thickness with the Solidify modifier (enable the Even Thickness option), or altE to Extrude along Normals and enable the Offset Even option in the Operator box:
And there you go, I forgot to take a picture of it but I hope it helped!
