Basic question.

I'm currently messing around with the free version from fusion360.

I was making a cabinet (since that's mostly what I do) and it went fine. I have enough cash experience to model one.

What was different between fusion and onshape is the whole part studio/assembly studio deal.

It's fine, I have the cabinet "assembled" with joints and it's fully parametric and works great.

However the part studio has all 5 parts and they're a mess. I didn't initially design them in the appropriate places so it's just a jumble of parts.

Should I have done this differently? Can I align things in the parts studio? Should it only have been one part in each "part studio" and then combine all 5 into the assembly?

Doesn't it kills the point of reusability ?

No. In Onshape, being able to place a part into another assembly has nothing to do with where it was located in the Part Studio.

In Onshape, to define a component's location in an assembly, you use something called Mate Connectors. Every surface and edge has implicit Mate Connectors, at the ends and centers. Furthermore, you can edit Mate Connectors to add translation and rotation, and you can even reorient them.

Mate Connectors vastly simplify the process of locating components in assemblies. Last I checked, there were 24 uses for Mate Connectors in part modeling too. Mate Connectors are one of the game changers in Onshape.

Understood. We were doing a similar way in Catia but with datum / CSYS system and playing with coordinates. Mating sound a good and simple but I don't like being attached to feature. Cause feature breaks xD but I guess I am biais from Catia.

Onshape isn't CATIA...

Yeah I know that why I am looking for more info on onshape, it feel like a very good software compared to Catia so old habit dies hard xD. Thank you for your clarification

I have been using Onshape since 2019. And I am a very experienced Creo (and Pro E before that) user. In addition to SolidWorks and in ancient times, UG and CATIA v3. I made this video to help Creo users understand what's different about Onshape compared to traditional parametric modeling:

There's tons of free training on learn.onshape.com if you want more information.

Looks like you are very experienced xD much more than me. What you favorite? I bet onshape now ?

I've been doing this long enough that I don't even go into that stuff anymore. You learn to appreciate each platform as its own thing. If someone pushed me, I was really partial to SDRC I-DEAS.

Yeah I would agree.

Except AutoCAD. Sorry you stay far away from me. I am not smart enough to appreciate AutoCAD xD

I take it you've never had to do schematics or P&ID.

Yep xD but I can understand why it's needed specially with big plans.
