Importing CAD with 4.1

[firehaus]

Hi everyone. Wondering if anyone has experienced any problems importing cad files in 4.1. Every time we try and import a cad file, you can expect to wait at least 15 minutes while PcDmis draws out the cad file. Even tried importing wire frame only and this only improves the importing capability slightly. With 3.7 and even 4.0, we never had any issues with importing cad files. Any ideas?
We are using Pent 4, 1 gig ram and 128mb video card. TIA

Ive not had any problems while importing from a 3.7mr2 or 4.1 Pcdmis cad file, or from an IGES. My computer crunches out about a 110mb IGES to PCDMIS in about 3-5mins I think. That would include the time it take to save the file after everything looks like its done the first time.

I did however have PCDMIS lock on me once while trying to import as a IGES alternate. Otherwise no problems.

I have no problems importing iges files with 4.1. What software is creating the iges with? ie: mastercam or solidworks. that could be the problem or you might want to make sure the setup is correct , before clicking on process. Just a thought.

We have tried importing from both the original cad file (Catia) and another generated in Mastercam and have the same results.....very slow.

I have what seems to be a similar problem. It loads the processing portion real quick and then gets "stuck" at 95% when it redraws the CAD. It takes 20 to 30 seconds in my case, to load the last 5%.

I also did not have this problem with 4.0. It started with 4.1.

I brought another model down in V4.1. That is also fairly big. It loads fast.

Could this be a problem with models that were created in an older version only?


Sorry for not being of much help. I have reverted to turning my CAD models off as much as I can. Otherwise I am sitting there waiting forever.

Thanks Jan......Our troubles are similar to yours. The cad loads quickly until we hit the 53% mark on drawing the cad, then it is coffee break time. It'll take another 15 minutes before the file is completely imported. Unfortunatley we must have the cad for this job and cad loading times are killing us.

Looking at the thumbnail it's setup the same way as mine. we don't use catia at all. Sorry, no help. I'm still thinking on it.

Can you post that model?

Here is what I have:

Slow loader:
Model created using the CAD direct interface from Pro/E in 3.7; size: 58,000kB. Time to pull up in 4.0: time it took to process (quick; acceptable). Time in 4.1: time to process plus about 20 to 30 seconds (from 94% crawling to 100% redraw). Quite unacceptable.

Model that loads quickly:
Model created using the CAD direct interface from Pro/E in 4.1; size: 32,000 kB. Time to pull up in 4.1: time to process plus about 3 seconds to redraw. Can hardly see the progres window on the redraw. Very acceptable.

Therefore my hunch: can this problem be isolated to models that were converted in pre 4.0 CAD translators????

Wish we could. The cad file is roughly 40 meg.

[mwiquality]

Are exporting it in mastercam as surfaces only? If not, that might trim the size of the file?

[firehaus]

Tried both exporting both wire frame and surface only and had the same results. Just tried exporting from Mastercam 10, not much difference. We have been exporting from Mastercam ver 9 not sure if that makes a difference overall or not.

Do you need the cad file as part of you're program? If you don't after you program it maybe delete the cad file or hide it?

[mwiquality]

Got another question for you. Is there any iges types that are not processed when you import the iges.

You gotta be kidding.
20 to 30 seconds?
I imports some large CATIA assemblies and 10 to 15 minutes is not rare...
sheesh!
