Great tip. This has got to be the best speed tip for Wildfire 5 I've seen yet.

have the Creo 1.0 license, but I'm required to do a particular model in WF4. are there any options for that version that may speed up large patterns? particularly perforated metal.

You can do a surface copy of the feature(s) and then pattern the surface instead of the actual feature(s).

You then have the option of either removing or filling material using the patterned surfaces when you need to. This technique was used to improve large pattern performance prior to WF 5.0.

sounds exactly like the answer i was looking for. can you maybe explain the process a bit? how would i go about doing a surface copy? when i try to select the inside surface of a hole feature, it just selects the part or the hole feature. i'm working in sheetmetal mode if that makes any difference.

i appreciate the help.

Select both sides of the hole by holding down the CTRL key. Then go Edit -> Copy and then Edit -> Paste to get a surface copy of the hole.

One other thing, sounds like your Smart filter is on. Yes, select the hole feature first, and then select the individual surfaces.

Chris. Not sure what the geometry looks like, but you mention a hole. If that is truly the geometry you are patterning, then it will be hard to get the pattern to regen any faster using the surface technique John mentions. However, you can check in the pattern definition to make sure the pattern is optimized. If none of the holes intersect or partially fall of the edge of the plate you want to make sure you change the Option from the default of "General" to the more optimized "Identical". This should greatly improve the performance as long as the pattern fits the above criteria. Hope this helps.

It does not seem to work for Sheetmetal? only solid parts?

that sucks!!!!
