Large Assembly Drawings

Large Assembly Drawings

Large Assembly Drawings

(OP)
Hey Everyone:

Can anyone provide me with some suggestions on how deal with large assembly drawings (100-800 parts in the assembly).  Seems like catia gets very slow or unstable when dealing with large assembly drawings.

Thanks

RE: Large Assembly Drawings

Hi,

Use cache mode to load your assembly. I've managed to create a drawing from 3000 part assy with exact views using cache. Of cause amount of memory consumption is dependant of
number of different parts in assembly. In my case there were ca. 800 different parts.

You can also use approximate views to generate your drawing from very large assemblies. We've made drawings from complete paper machine line assemblies w/ approximate views.

Windows XP with the 3GB switch and your CNEXT process set to use it.

RE: Large Assembly Drawings

Hi,

I may be wrong on this one but what is the use of trying to create "Exact views" with cache mode? Don't you have to use "Approx View or CGR" to have any use of the cache mode?
When I use "Exact views" the design geometry (not the cgr) is loaded.

Akesson,

If you use cache mode and project an exact view only necesary information from parts is loaded, not all. This is so called brep mode. This way memory consumption is more echonomical than using design mode. Of cause it takes more memory than projecting a view in approximate or cgr mode.

eklunja,

Thanks, now I've learned something today.
Useful information when working with large assembly drawings.

RE: Large Assembly Drawings

Hello,

My previous explanation about brep mode applies only for folder based usage of Catia for older releases. R15 is first release that has this ability when Catia is used with VPM (I don't know what is the situation with other database based PLM programs)

RE: Large Assembly Drawings

Actually, it was available in R12 for database models, but only at certain service packs, and it had problems.  They took it away from us at R13, and it really caused us some problems.
