Hi Andrew - MoI does export object names though to the OBJ and LWO polygon-based formats.

It is possible to write only triangular polygons to either of those files, so doing that would have a data file with the information in it that you needed. But I don't know if the particular program that you are importing into supports those formats.

If not then you might see if some converter is available that can convert an .obj file into the kind of format that you can read, one that you could try is MeshLab:
http://meshlab.sourceforge.net/

Because STL format is so limited, it's not a great way to translate multi-object organized structures between programs - OBJ format works better for that.

Thanks for your response.

I simplified my description for the sake of the brevity. My building will have an open roof so I will model the flow around and within the building. Obviously I will need to create a ground object, as well as inlet, outlet, etc.

PS. The software I am using is not mine, but rather a commercial product I have bought.

Dear Michael,

Thank you for your very quick and helpful response. I will obviously have to think more carefully about this.

The CFD software I am using recommend something like CATIA to prepare the geometry, but that seems way over the top (in functionality and cost) for my purposes.

Thanks again.

Regards,

Hi Andrew - also some times analysis software is able to take in NURBS data directly and generate its own mesh from that.

If that is supported by your software, look for stuff for either the IGES or STEP file formats - MoI can export to those formats as well.
