Mastercam's Tool Designer lets you create 3D tools to use when simulating your toolpaths. 3D tools give you a more accurate simulation result, showing collisions that might not display when using a 2D tool.
3D Tool Support Build tools from 3D STEP models using the Tool Designer. The Tool Designer is a function panel with tab-style navigation, providing a structured workflow that is similar to using a wizard. You can define tools, assign them to operations, and view them when running Classic Backplot and Mastercam Simulator.
