Probably a stupid question...

But how can I add features such as a weld to a completed assembly? I have an assembly consisting of 4 vertical walls that make a box, and a top and bottom plate that enclose the box. I think I have everything mated together, but now I need to add a fillet (weld) where the top and bottom plate meets the walls. Is there anyway to make changes like this to a completed assembly or do I have to somehow mate everything together in my parts studio and add the welds before bringing everything into an assembly? Thanks

It is actually preferable to build static assemblies in a part studio, not just because it makes it very easy to add welds (using Extrude, Sweep and Revolve) but because static relationships can be more quickly and easily created by using constraints rather than mates.

and there is currently no way to make changes to parts in the assembly mode. And if you do as @andrew_troup suggests you won't even have to do an assembly, moreover is you are clever about how you do your sketches you will not have to check if everything lines up and has equal sidelengths etc, it is all handled directly, so it is a great timesaver.

Thanks guys. I think I'll stay away from assemblies for awhile and just sketch everything together to start with. So far I'm loving onshape!!! Much easier than freecad amd less expensive than solidworks.

Sounds like a good plan.

The future time to grapple with assemblies is when you want to define relative motion between parts.
