In CAD modeling, you can use boolean operations to create complex shapes and forms of your models.
Subtract is one of the boolean operations in Shapr3D that you can use on overlapping bodies to remove or subtract the volume of a selected body from another body. To use this tool, you must have at least two overlapping bodies.
To use the Subtract tool:
-
Go to Tools > Subtract.
