3D Interoperability

I've a big part as .CATPart and x_t(parasolid) file, Parasolid kernel opens up the parasolid model and displays in 40 seconds whereas CATIAv5 (through Interop) takes more that 4 mins. CATIA model has less number of rendering triangles than parasolid model so triangulation is not an issue here.

During import I do get some messages for CATIA model:

"-- building late types C:\Code\Debug\lib3dx\intel_a\code\dictionary\meta_container.txt"

"can not find CATContainer"

"model unit: millimeter"
">>EXTREME SCALE : Current CGM Scale factor = 1"

"CATRoll Class Information"

"CATTemp Environment variable is not initialized"

I don't get any information about the cause of these messages. Can somebody tell me if these messges are important and how to solve the issue? I want to speed up the model load process. Attached zip contains the parasolid model (from which I created CATPART) and catia model import log. This part is small and takes less time but throws same errors as above.

I've already included the lib3dx path in PATH as mentioned in http://doc.spatial.com/index.php/InterOp:Connect/CATIA_V5_Installation

Thanks

attached the zip file containing models.

Hi,

These messages comes from V5 toolkit, i.e., dlls present in the lib3dx. There is no action needed from your side on these messages and there is no problem with these messages. These messages have no effect on translation time.

Thanks Venu.

Are there any other things that I need to do for good performance? Also, can I safely assume that CATIAv5, sat and sab files will have mm as the units? I'll not have get the source header info then.

Cheers!

Hi there,

Nothing much can be done for V5, we have observed that for second time onwards it runs faster may be as it uses OS cache.

V5 always have mm as unit. But you should be careful in case of acis, acis file may have different unit other than mm.
