The SOLIDWORKS 2019 Interference Detection tool can be used directly on a multibody part. This is very useful to check weldment parts (or multibody sheet metal parts) for any potential interferences that need to be reviewed. Previous versions required other solutions such as combine or inserting into an assembly.
This is also useful when running Simulation studies on multibody parts. Simulation studies will fail with any interference of bodies. This tool will help locate the problematic regions.
The Options are similar to assembly Interference Detection. There is an option to ‘Skip interferences inside inserted parts’. If you insert another part into this part, any interferences contained within the inserted part is ignored. However if the inserted overall part has interference with your component, this will still show up.
