7.3. Multiple workpieces

When you add more than one workpiece to a milling simulation, only the first one will be solid.
All additional ones will be shown as transparent ghost- like workpieces.
This is a limitation in how the workpiece buffer work in the simulator, and it is also to protect from out of memory errors, as a workpiece buffer takes up lots of RAM and CPU resources.
If you have a powerful computer that you think can handle this, there is a work- around.
You can simply make one large workpiece that you cut up to smaller pieces, with a simple CNC program. Then you can save this as a prefabricated workpiece and use in you projects.
