Ok I managed to do this...but ran into another problem.

When I export this as an stl file (set to more polygons) and import into Vectric vcarve the surface is not smooth.


What can cause this?

Tnx!

Hi Matadem, you can get that on shapes that are large but only shallowly curved.

For those kind of shapes you'll need to adjust one of the additional meshing parameters so it will subdivide it more.

Press the little arrow in the lower left corner:


That will show some additional meshing controls.

Then put in a distance value in the "Divide larger than" option. That will divide any polygon larger than that distance.

You don't want to put too small of a value in there since you don't want to generate 100 billion triangles. Start with something around 1/20 of the distance across your model and reduce it in steps until you see the triangles are small so capture more detail but not microscopic.

For your model here a distance of 1 unit would be good:
