Saving assembled parts on same coordinate system

[creilly]

Hi,

I have been given 20 CATIA part files. I have created a CATIA product with them all correctly aligned using the constraints feature. It is a casting die, so it is important that the surfaces of each part qare correctly aligned with one another.

I would like to export each part as an .STL in order to import them into a CFD software. I want to export them using the same coordinate system so that they are correctly aligned when imported into the CFD modeling software. How do i do this?

I have used solidworks before, in which you have the option when saving as an .STL of using either the part or assembly coordinate system. However, I don't see a similar feature in CATIA, and can't work out another way of acheving the same thing.

I am using CATIA V5 R20

Any help would be gratefully appreciated.

You need to export them from the product level for their locations to be held. This command is available in Digitized Shape Editor, Shape Sculptor and STL Rapid Prototyping. However STL Rapid Prototyping lets you export to STL only. BUT, you could use the command Tools --> Generate CATPart from Product to create a part file of all the parts. Then you can hide/show the each partbody you would like to export as an stl. I recall the stl tolerance is related to the level of detail set in Tools - options - general - display - performance - 3d accuracy.
