Generating Drawing from large assembly

Generating Drawing from large assembly

Generating Drawing from large assembly

(OP)
We have main assembly currently containing 1000+ parts. But still one sub-assebly of 900 parts is excluded from main assembly. We've tried to bring that sub-assembly to the main assembly, but CATIA always went down.

Our platform is: CPU 2GHz with 2GB RAM, ATI Fire GL2 64MB, 100 Bbit/s network. CATIA V5 R8 SP4. WINDOWS2000 SP2.

We need drawing from that whole assembly (almost 2000 parts) while we aren't able to do the Product complete. CNEXT process size reaches 2 GB limit of CATIA(?)

Does anybody have ideas how to generate drawing?

RE: Generating Drawing from large assembly

I don't have the definite answer. But here is an idea.
Look to see how much memory you are using. If you are hitting near the 2 gig limit of your machine, it may require an expensive fix. I have heard that windows 2000 will not support more than 2 gig per process thread. I have also heard that Windows 2000 advanced server will allow up to 3 gig per process. I expect Windows advanced server is not cheap. You could try to up the virtual memory, but I don't think it will help.

I had in seen a post in a workstation review site that depicted this problem for those dealing with very large assemblies.

RE: Generating Drawing from large assembly

Hi there

I'm afraid that you will have to wait until V5R9SP2 to be able to create a proper drawing of your assembly...
Then you will be able to generate a view directly from a product in Visualisation Mode, which saves plenty of memory.
 

RE: Generating Drawing from large assembly

Another solution is to shrink the data of your sub-assemblies by removing the history of the models. This method is explained somewhere else in this database. Basically, you create a new assembly, add an empty part to it and then load your sub-assembly. Select the new Part and make sure you're in Part Design. Select those bodies which makes up the exterior of the sub-assembly, if you don't want to section the sub-assembly. Now, on the insert menu you'll find Boolean Operations - Assemble... Use that and select the PartBody as After:

Save the part and discard the new assembly as it can't be used for updating your new part. Use the new part instead of your sub-assembly in your top assembly.

Please tell me how much less memory is consumed.

Good luck

RE: Generating Drawing from large assembly

Hello,
I have to customer with same problem. The customer solution at this time:
split the assembly in 2 assembly. One assembly whit all the outside parts and subassembly and the with inner part (example only). Start a new drawing and you generate the views from both assembly in same drawing.
But in very short time we get a solution from Dassault/IBM
Best regards
