Import
Import the LSR file for the simulation.
If you choose an LSR file that describes a multi-axis process instead of a 3D process, you are also asked to specify the substrate type. This is either a cuboid derived from the bounding box of the LSR coordinates, or can be from a 3D model file that you load in a subsequent step.
Save
You can save your project here at any time. If the project is saved for the first time, you are prompted to specify name and location.
Strictly speaking, manual saving is optional: Upon generating a mesh preview or starting to solve, you are prompted to save the project anyway. But you may want to save and continue working later on.
