Re: align views from different inserted views?
This is the closest one I can find. Not sure if this reflects everything in this thread.

Re: align views from different inserted views?
Anyone got a link to the improvement request so I can vote up?
Re: How to create a custom linking some parts
The minimum inner radius of your face must be at least as large as the thickness to avoid intersections/errors.

Re: Custom Frame FS without precondition
I forgot hardcoding PartStudioData to the frame library isnt exactly straight forward.
First step: check out this sample document I made:
https://cad.onshape.com/documents/a2b5b75e5174310d936a970c/w/808034fae6b6481349311183/e/60b8daf9eb1a25c9d740c667
You have to import the correct part studio, and construct your own PartStudioData object by providing a build function and a query (and config if relevant).
If you want a custom profile, just import your own part studio containing an origin centered sketch.
If you want the onshape standard library, its a bit tricky because you need to find the document that has all the frame profiles, but Onshape does a good job of hiding them.
Open the test feature, and use the PartStudioData input to select the frame that you want.
Then, right click your part studio and do "show code". Find the definition of your feature, and the input for the frame.
Part of it will be the "namespace" of the frame. Something like:
"buildFunction" : d1828c2eb863ee177b5a1d699::v3c4bdd532757091960c24147::e56edb720718e8472f9247fc3::m5bbec7fb947ae50c13245ba7::build
And you need to reconstruct it into a url like below:
"buildFunction" : d1828c2eb863ee177b5a1d699::v3c4bdd532757091960c24147::e56edb720718e8472f9247fc3::m5bbec7fb947ae50c13245ba7::build
becomes:

careful to check that each ID starts with an extra character, d/v/e.
Find the correct tab, and then import it into your featurescript (for example, see line 7 where MYPROFILE is the namespace of the profile I picked).
I do this by opening the tab, and then going back to my featurescript and clicking "recently opened", or just copying in the URL.
Re: Explicit mate connectors in part studios -- what is the proper use of this feature?
Explicit mate connectors, with parts as owners, can be a good way to make sure that the references are managed properly as you're modeling. It can also be good for defining MC locations which are difficult/impossible to do in an assembly (e.g. the end of a coiled compression spring, or a swoopy consumer product housing). In many cases I will define a mate connector at the origin of the part studio or perhaps some other virtual point which requires sketches or planes in order to keep it parametric.
There are zillion uses for mate connectors beyond just mating parts, but I don't think that's what you're asking.

Re: Explicit mate connectors in part studios -- what is the proper use of this feature?
I often add explicit mate connectors to a part when I know how it's going to be assembled and, due to the geometry, there won't be an implicit mate connector to make the assembly work.
Re: Explicit mate connectors in part studios -- what is the proper use of this feature?
@james_aguilar160 , Matt answered the mate connector question, but I would like to talk to you about some of the other issues you brought up. Are you aware about edits causing changes to part names, and lost face geometry - and the resulting issues of broken mates, that these changes bring about? This sounds like what you are experiencing - Others may be able to explain this better than I can.
