Long Regen Times on Sheetmetal Parts

brucebartlett

I am having trouble with sheet metal parts running away with excessive regen time and I am trying to understand why some features have long regen time yet other are low.  

See this part.  Any extrude remove I put on the blue part takes over 2- to 3.54 sec's where the grey part in only a fraction of a second. Why is this? https://cad.onshape.com/documents/83f8c0388a675308d082ec53/w/c1b17eac5f4baf29fa383e23/e/b00df9e28be5bb9b6cfb1775

@brucebartlett
Perforation of sheet metal faces causes slow down of downstream features. We are working to improve this. For now, you'll get better performance if Extrude 1 and Extrude 2 are moved to the bottom of the history.

Thanks @lana this is good info.

Howdy.

I might be tempted to throw those extrudes in a configuration that suppresses them in a "Low Detail" mode but shows them in "High Detail".  It'd be an added layer of risk to ordering incorrect parts if left in the wrong state though.

O.S.
