hmm....
I think I can solve the position by:
creating a tiny "node" object like a small cube as a subobject for each part
then can I get the position of the bounding box of the node.
but for orientation, I'd need to know the rotation of the node.
I thought maybe a cube (as a primitive) would have orientation.
But playing with "Separate" on a cube, I see that it's composed as 6 planes to enclose a solid.
So when we rotate, moi just transforms the vertices?

Hi Jeff,

Yes, that's correct.

But if you are able to attach some additional node objects to each main object instead of doing a cube if you did a 3 orthogonal lines one for x, one for y, one for z, that might be workable.

For importing into Unity, I think it ignores points and lines.
Only meshes are imported. So maybe three triangles in the form of a corner to represent the axes.

There is a solidworks to urdf exporter:

Hi Jeff, sorry I'm not understanding the part about importing into Unity - I thought you needed to write the rotation information into an XML file.

sorry for the confusion - I have URDF which I use for the physics engine import, but
I also to import robot models into Unity using URDF for easy visualization and PBR rendering.
(you can see some examples at my website
www.spryrobotics.com).
