I heard somewhere that using multibody patterns vs a feature pattern is faster. How can you use multibody inside of a sheetmetal part? We mainly do sheetmetal and sometimes have to pattern lots of slots for guards/etc.
Body patterns are faster than feature patterns because you don't have to pattern the intelligence. Sheet metal didn't allow multiple bodies until recently, so there are probably fewer multi-body techniques developed for that. One thing that comes to mind when talking about patterning large numbers of holes in sheet metal would be to make a small section, put a hole in it, pattern that as a body, then join it all back together. But that's the part that will make it all about equal is joining it all back into a single solid. It might be that there is little benefit for multibody patterning in sheet metal. Usually patterns that benefit a lot are patterns where there would normally be a lot of features with complex end conditions (up to surface) that can be patterned as a block of material.
Check out my performance benchmark carrier sheet metal model on my blog. This may give you some ideas. I pattern and combine bodies before I turn it into a sheetmetal part.
