Regenerating 1000 ....features

[camilia]

Hi
I need some help...I have a design with over 1000 features including many patterns and styles....When I edit a style feature and quit out of it, Pro/Engineer starts regenerating all those over 1000 features and it take around 45 min each time, can some body help me get out of this sh*t....

I suppose there is no straight, easy solution - all what is possible is left for some kind of work around.



I assume your pattern is based on some kind of surface/curve geometry(you mentioned "Style")



What I used to do in such cases is following:



1) decrease no. all copies in one pattern(I prefer to make few patterns with less copies inside)



2) try to avoid making copies of surfaces with solidify feature at
once(I assume that you can have style surfaces which are next removed
from solid or solidified and then copied by pattern).



In this case I try to copy surfaces first, make merge for first instance
of pattern and then Ref Pattern, and at the end solidify -> Ref
Pattern



insert a picture of pattern that all guys at forum could imagine the problem

Hi
I can't attach exact problem pic as due to confidential job nature but I have simplified my prob by rep in attached work.
1) the surface is made by using drop curve inside the same style, and when I want to make a circular pattern, I can select only this surface (drop curved), it selects the curves on the vertical central plane as well and make a pattern of it as well. I need to pattern only surface made by drop curved.

2) when I go into edit definition of this style, and come out, ....oh god.....it starts regenerating features from scratch, and for actual work where many surfaces, it is unbearable
plz help...someone

Btw, regarding you first question about the "pattern who also pattern the curves" and so on. Try to make a copy of the surf, and then pattern the copy instead. Should work. Its all depending on "whats next" and how you modell. Jacek has got a good point as usual. Can you upload a simple part that shows your problem?


Regarding exiting style and the regeneration.... well it

Just a thought...

Did you try to set the features BEFORE the patterns to "Read-Only" ?

This will force Pro/E to NOT regen any features before the pattern and will speed things up.

Also, did you try to use the "custom regen" icon button. It allows you to build a regen-set that will only update the items on the list. It may also help.

since proe is inherently parametric modeling it will regenerate all the features below a feature being edited.
it will NOT regenerate the features above the feature being edited.

(by above & below a feature i am referring to the feature tree!)
i guess you don't know about suppressing.
suppose you want to iterate a particular feature then you should suppress al the features below it.
after you are done with the iterations resume the suppressed features.

PS: while editing a feature don't delete any entity, as it might be referenced by the features below it & you will get a very big headache while resuming a feature whose references are missing!

Try splitting up the patterns in to many smaller patters that accomplish the same thing. Better to have 40 patterns of 20 features than 1 pattern of 800 features. Whenever you make a change it regenerates only the features that come after it, and it treats the patterns as a bundled group. Compartmentalizing like this limits that amount of features it will have to go through during regeneration.
<?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />
Also, try splitting the model over several part files. For example if you have a part file of 1200 features, and you know nothing before feature 800 will likely change, break that part off into another part file. Then read it back in with a publish/copy geometry, edit references of the children to use that feature, delete the first 800 features, and you will be left with a part file of about 400 features. This will be painful, but it is a one time pain that maybe better in the long run.
