Re: Cutting spherical shape

(This is the boolean tool, by the way)
Re: Extruding a half-round shape
Brilliant, sir. Thank you so much. That was shockingly easy.

Re: Is it possible to setup a gear mates and relation for a counter mechansim?
@max_tran483 If you're still working on this I managed to get it to work using a bit of trickery inspired by the Geneva mechanism @EvanReese mentioned.

Re: Extruding a half-round shape
you’re doing fine. Just use a Boolean subtraction on the tray and subtract the battery shape from the tray. If you don’t want to keep the batteries, just tick off the keep tools option in the Boolean operation

Re: help finishing a CAD/Onshape Best Practices document for a FIRST FRC team
@joshtargo 6 sketches (that are not humongous, say less than a few hundred entities each) is not expensive — it's a totally reasonable thing to derive into all the part studios in your design.
@S1mon Unfortunately, here I have to say "it's complicated internal reasons" that have to do with caching, referencing, configurations (as a result of which we may not know what we're deriving until we're part way through the derived part studio regen), etc. Basically, derive is a very different and in some ways more flexible mechanism. We have thought about having a lighter-weight version of derive, but haven't yet figured out a solution good enough to implement.
Re: -made a part with variables; how do I paste the variable table to a variables studio?
Hello Christopher. Check this post out. - Scotty
Re: Placing Derived Parts in an Assembly
You can insert your master sketch into the assembly and mate the parts to it.
Or add explicit mate connectors to the parts (based on a common reference on the master sketch)
Re: help finishing a CAD/Onshape Best Practices document for a FIRST FRC team
Why is derive more expensive than in context? That doesn’t make much sense. Is there any way to make them more equivalent?

Re: Sheet metal cone
If you want a smooth flattened part you can model it as a surface and thicken the flattened surface later. The new surface flatten feature can flatten almost anything. From circle to rectangle, containing a fillet with torsion distortions, no problem, I think this new feature is even better than in Solidworks. The only drawback is that after exporting to a parasolid file, the bendlines of the flat surface have disapeared.
Re: Order of split body parts
So, I'm now taking the output from evaluateQuery and sorting it based on evBox3d minCorner of each body - seems to work.
