Constant Material Removal on Non-Flat Surface

3D Design Volume Model
1

Hello I want to remove material from a part (imported body) that is not flat. (e.g. office chair backrest)

I wanted to try using the winding function, but it doesn't work.

Could someone enlighten me?

I'm on SW 2014.

Thanks in advance

Hello

Create a sketch that follows the shape of the seat back and remove material. You create the profile to be removed in a new sketch at the end of the guide sketch then you exit and select the two sketches with CTRL and click on the material removal function and there it should work...

- Create a face offset by 0,
- thicken the value of the material removal,
- combine bodies by subtraction

So I did a material removal by scanning, less realistic than what I would need, but quite explicit.

Thank you for your answers
