macros

Hi
I am running a macro that extrudes spheres out of a cube. I ammodeling porous objects. Is there a way to run a macro withoutshowing all of the operations. Some seem to think that it is usingmore memory and time. I am using the 64bit ed of solidworks on adual processor machine with 16 gigs or RAM! After about 500 orextrusions the programs slows down and starts skipping sketches orgives sketches and doesn't extrude. We know this has a lot to dowith memory, however, trying to find ways to increasememory.SolidworksApi macros
