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

It is another level of CAD to do 3D but just takes time and patients & a good use of Z-snaps. :)I have done a few 3D items but am still learning.  https://sketchfab.com/ab2draft/models

Hi,
Thank you for your answer.
I saw your models but probably they were made with sketchup that works with surfaces.
I need to get 3D Solids (ACIS).

Is there a way to create the file that I have attached in AutoCAD or BricsCAD?
What are the commands and / or techniques to achieve this result?

CAB:
The USCG, Grate & St Thomas were made using BricsCAD.The others were made using Chief Architect.
Looking at the chair, I would think a modeling software other that CAD would be more appropriate.I think it could be done in CAD but that is beyond may skill set.

ChrisCarlson:
You're already kind of half way there. You just need to convert the mesh into a solid. Check out the command convtosolid.

Unfortuantely, the program which outputted the mesh did a crummy job and I don't there is an easy way to really accomplish what you need quickly.
