If you have the SolidWorks Education Edition or your mentor has a SolidWorks Commercial Edition you can utilize the Add In called Feature Works to make non parametric features from IGES/STEP/SAT into recognized ones.

Also from within SolidWorks, you can select on a face from imported geoemtry, create a new sketch and extract geometry in a Sketch with the Convert Entities tool. This technique is usually the most helpful because you really dont want to spend a great deal of time converting all imported parts in an assembly if you just want to add a few holes to a mounting plate.
