BIG part is very slow
BIG part is very slow
(OP)
I have a prt file of "just" a plate which is 100mb large. I wonder why this part is soo large. Is it because there are many many linear patterns in it. All the distances between the holes(groups) are different but each big hole with bolt holes around it (group) are the same. That's why I have many patterns of a group of holes.
If I do a small change it takes almost half an hour to update.
What can I do to make it more workable?

RE: BIG part is very slow
Yes the number of patterns may be an issue.Now as a workaround you may collect all these patterns in a Feature Group and keep it suppressed during model edit and when you are done then unsuppress it again.
In case this is not acceptable to you then you may try PREFERENCES/VISUALIZATION PREFRENCES/FACETING/SHADED VIEW turn the resolution to coarse.Though this may not give you much leverage but at least it will make the manipulation of model a bit easy.

Try this if acceptable ...export your part (till all the patterns in the feature history) without history to second part file...In this second part file now you will be having one unparametrized solid in the begining ..do the edits and then re-import this part (along with history this time ) in the original part.Now Replace the unparametrized part (first body that was exported in the first step) with the original body (or the last operation till pattern) and delete the unparametrized body.

This setting stores additional information in the part file which helps to reduce the feature update time. I think it's switched on as default.
Turning this off may improve the situation. (Just make a backup before you save).

RE: BIG part is very slow
I don't understand your suggestion kapmnit123 with exporting. But if I understand right I will loose some history that way.

RE: BIG part is very slow
No you wont loose any history at all.Sorry i guess i was a bit messy with my reply.
Let us say you have MODEL1 with the plate and quite a number of instance features.Do not do any editing/create on this part file instead create a new dummy file MODEL2 and export the part (plate along with instance features) from MODEL1 to MODEL2 as an unparametrized body.Now whatever operation you wish to do can be done on MODEL2 let us say you added some features to it.Now once you are done then re-import the complete history (even a copy/ paste of feature history will do)of MODEL2 back to MODEL1.So now in MODEL1 you will be having the original model and also the one with history from MODEL2.Since the history tree of MODEL2 started with an unparametrized body so this will also reflect in the final MODEL1 history.All you have to do now is use REPLACE to replace this unparametrized body inside the MODEL1 with the actual one (with history which you exported to MODEL2 in the start).Since the number of faces/edges will be same in both so i guess these can be replaced easily and now once it has been replaced successfully get rid of the unparametrized body (so delete it).
You can do a trial run of it on any dummy part first.

RE: BIG part is very slow
I can give it a try but I am afraid that the model will start to update completely once I've replaced the body by the original body. And this updating takes so much time.
But it may be worth the try. Did you use this earlier succesfully?

RE: BIG part is very slow
No frankly speaking i have not used it quite often .Actually i have tried to re-enact the PART MODULE methodology (starting from NX8) to some extent.Mine is quite rough and not as refined as it but can be utilized from NX7.5 perspective.

RE: BIG part is very slow
I think you should use pattern face instead of instance feature-
in all cases where you don't need them for fastener positioning...
RE: BIG part is very slow
Actually I don't feel like building up the model again with pattern face.
