When save toolpath rhinocam?
Every time you save the file. Assuming the license is valid and working.
I think there three things here.
i)…When you save the Rhino model the toolpaths are saved with it.
ii)…You can save the toolpaths in the MecSoft/VisualMill format and use them in another model. Obviously in the next model you’d re-run RhinoCam so that the toolpaths matched the new models, but it saves respecifying the parameters.
iii)…You export the toolpaths in a format suitable for you machine when your happy with them.
