STEP, hands down.
It is reasonable feature complete. It is an oficiall published 
standard (ISO 10303). And it is univerally accepted. Virtually every 
reasonable 3D mechanics CAD package can do port/export in STEP. If a 
vendor supplies 3D models of their product, chances are, it is in STEP 
format.

Only downside is, that STEP is a behemoth of a format. About the 
extreme opposite of the PCB format ;-)  Some time back I hade a 
cursory glance at how it does basic 3Dgeometry. Afterwards, I knew, 
why kicad or eagle developers chose VRML for their 3D ambitions. 
For this reason, I'd recommend to not do a STEP importer/exporter 
locally. Instead, talk to a third party application whose programmers 
have already mastered the task.
