Inventor: Improve performance of a part that is later used in a pattern

Anonymous — Mon, 19 Nov 2018 09:38:36 GMT

I have a part that is two extrusions joined together by a loft. That part is then patterned several hundred times- if this were corrugated tubing, I am modeling one corrugation and then using a pattern to create the rest of the corrugations.

My question is, is there an order to these commands that would be the most efficient/resource friendly? Does it make sense to make the two extrusions, loft between them, and then pattern the three features, or would it be better to pattern the two extrusions first and then have a single loft between the two patterned extrusions? Does it not make a difference? Would it be more efficient to do the pattern in the 2d drawing and extrude that first, so it is two total extrusions and the one loft between them?

Thanks for the help, trying to do anything I can to minimize slowing down Inventor as this part will end up in a larger assembly and is patterned there as well, and it can really kill the ability to do anything to the model once its all in there.

Hello @Anonymous!

Could you maybe post the part so we can take a look at it? We could give you then a hint on how to improve your part.

Mostly it depends on how a part is created but there is not a general answer to that.

Thanks!

Pattern Body rather than feature is usually preferable, but without a file or even a picture it is hard to offer any other meaningful advice.

Hi! Within the part, do these tubes need to be separate bodies? Or, they can be disjoint lumps of one body. I think the best performance you will get is to pattern the body, like JD mentioned, and set the result to joint as one solid. Could you try it and see it if works better?

Many thanks!
