Best modelling workflow for multi-part

Josy_La

I am custom to Inventor and SolidWorks, both software are use differently to obtain an ideal workflow for multi part assemblies. Of course there are other ways to use these platforms. Outside Featurescript what would be the best workflow in OS to create adaptable static models?

We are presently using a skeletal modelling technique to create our multi-parts assemblies. But I've also worked with a different approach using a wire and generic parts library that can be stretch and applied onto that wire to generate the multi-part assembly. In my OS investigation the skeletal method seems to work fine but did not have success with the other approach.

If your manufacturing process is similar and you do not utilize FS how do you use OS?

Thanks for sharing.

Everything that is static (ie. no motion, they can be parametric) can be easily modeled into single part studio. Parts with motion I tend to have as subassembly so I can set limits etc. only once and just insert to any assy. When inserting whole part studio into assembly all static parts can be mated with one group mate which is a real time saver comparing to 3 mates per part system (Alibre).

I have to use the assembly tab to create sub-assembly groups. Can I have groups within one big group to prevent mating all the parts?

@3dcad was getting there, but essentially the Part Studio is where all of you components are constructed for your entire assembly. The Assembly Tab is then used to check motion and relationships between parts. This requires a different mindset, especially when comparing Onshape to other programs like Solidworks. In Onshape, you can create all of the parts in the same tab, allowing constraints and feature end conditions to be entirely parametrically controlled by variables and relations between parts. This past summer I CADed a new workbench for my room and I made it entirely parametric. Check out the the document to see how I did it:https://cad.onshape.com/documents/ee1d0f137b1172ea763f1238/w/8091713f81780cc937747308/e/3cc1ec53ea38482f5d85f305
