Long Regen Times - Sheet Metal Features

nick_coppins

With the new regen time tool, I've discovered in a particular model that 3 sets of holes (extruded slots/circles) in a sheet metal part are causing almost 50% of the regen time. In fact the sheet metal part in general is making up most of it. 

Can anyone tell me why this might be? I've closed the sheet metal design, but that didn't make any difference. Thanks

@nick_coppins Sheet metal is a newer addition to Onshape and these functions go through a number of iterations to improve performance.  Cuts and holes today can be more "expensive" with respect to regeneration.  Closing the sheet metal design will not impact this regeneration time, as you discovered but in many cases if you add those cuts at the end of the tree and roll up before them as you build, you can get some performance bumps.  We are aware of these situations and are hard at work to improve the performance as we iterate every 3 weeks.  Tools like the regeneration times can give insight to what is expensive and either reorder, suppress or consolidate them.

@lougallo Thanks for the forthright response Lou, appreciate it. It's not a huge deal for me as this is a small part studio but just something I noticed. Looking forward as always to the frequent improvements.
