DM Reading WRONG Surfaces in a STEP Body
 

I'm having a problem of finding lots of surface bodies in Design Modeler in my Geometry, even when the assembly I have is appearing to be all bodies on SOLIDWORKS.



The next step is my case is supposed to be adding an enclosure than using Boolean to make my domain. How do I get rid of these unwated weird surface bodies???


I tried both IGS and STEP for importing the assembly.
