Discard Selected Construction Geometry
In the process of modelling your project’s geometry, you might end up with entities that no longer serve a purpose. If an entity has no supports, boundary conditions, etc., and its role is set to Construction, then you can discard it.
Select the entities you’d like to remove. Ensure the Role is set to Construction.
Select Geometry > Discard Selected Construction Geometry
This removes the geometry from the model.
