Hi everyone,

I know AutoCAD and BricsCAD 3D regarding the modeling of 3D solid objects with flat surfaces (extrudes, Boolean operations, etc.)

Unfortunately I don't know where to start to model the seat of a chair that has an uneven shape (see attached file).

The result of the modeling should be a 3d solid and not a mesh.

Can you give me some indication or video tutorial on how to start?

Thanks in advance.

Lupo
