Now you can use STL models for surface projection — especially useful for painting operations where accurate surface normals are more important than exact geometries.
In painting operations, movement along the normal is often required, and STL format is sufficient.
You can now create a simplified surface model.
Assign this model as the machined surface.
Use it as a projection surface for toolpath calculation — STL is now supported.
The machine axis orientation is controlled by the simplified surface, while the tool itself moves along the original STL model.
