Simulating builds for additive manufacturing
The Simulate Additive Toolpath 
tool lets you visualize the manufacture of an additive part, animating the build process layer by layer. Simulating gives you the ability to see the different structures of a part, such as infills and supports, and verify that the build is as expected before you post process the toolpath or export the toolpath as a 3MF file.
Note: You must generate an additive toolpath before you can simulate it.
Example of simulation for an FFF build.
Note: This feature is available only when you select a machine with additive FFF, MPBF, or DED capabilities.
