I’m trying to make this airbag delete for my car, but i don’t have idea on how to make the curves, there is any way to make this on shapr?

Instead of modeling to make something fit to the mesh.

I would first remodel the original mesh and create the joining part.

At least for me it’s always easier to start by duplicating the mesh to cad model and using that to create the negative piece.

The main challenge is that all the borders are **organic** , so they must **align perfectly** with the 3D scan

I’m managing to make it work, but it requires several **complex workarounds** to ensure a perfect fit.

Well, just worked hehe, but it was really hard, i think shapr is not the right tool to make that kind of model.
