I am currently about to start a group project in Inventor 10 and wanted to know how can people make parts and submit to one person so he or she assemble them in a UCS environment.
Long story short (every one works off the same xyz/ucs coordinates?
I would use origin point as my reference. You could then create offset work-planes from the origin to start modeling for each part created. This way the person assembling, would only have to the origin of each part to the assembly origin.
You would want to establish which way the +/- for each X, Z and Y work-planes reference your model.
FIRST I assume you mean IV 2010 NOT 10, and i think you are referring to what aerospace calls a water plane but t plane if I remember correctly. It's been a while. Each part has a specified distance from this plane. IV has no problems with this approach, as it's already setup with a 0,0,0 point and planes, but I can see problems if you plan on reusing models and your'e designs do not use the same part in the same location on every design, and if you're doing much smaller projects.
Each part will just have to have a set of work planes put in at the start of each part. Aircraft companies really don’t have as much a problem with this, as to the project time frames and groups of designers and engineers are more dedicated to a single project.
GOOD LUCK
