Re: Imported part - can't select plane for Sketch, or merge parts
try using the Mate connector icon and then create a mate connector on the fly that has the origin on one of your imported mesh vertices…
You can further control the primary direction of the mate connector (i.e. Z axis) if need be.
Re: Imported part - can't select plane for Sketch, or merge parts
It would be much better if you could import something other than a mesh. It's possible to work with mesh parts (OBJ, STL, 3MF) but it's much easier to work with STEP, Parasolid, Rhino, or IGES (all NURBs CAD formats).

Re: Request: sketches should be usable as planes
That can be done with the mate connecter in sketch dialog. In this example sketch 2 uses sketch 1 location. No extra plane required.
Re: How to cut a larger piece for 3D printing?
Along with Evan's advice, once you have modeled an interlocking method (I use dovetails) I suggest you model smaller parts using whatever interlock you've decided on to discover how you will probably need to 'tweak' the joints to ensure the joint will actually mate properly. From experience, I've found that a filament printer (at least the one I used) cannot attain the precision required needed to allow the joint to succeed. - Scotty
Re: How to cut a larger piece for 3D printing?
The Split feature can make it into 4 parts. I'd consider adding some kind of interlocking system to the joints to force it to line up and add strength there. Or get fancy and laser cut the top out of aluminum on sendcutsend.com (or something) and attach 3D printed parts to that, probably with screws.
Re: How to fillet intersections?
Ah, found it! I merged the two parts into one and the fillet function suggested the intersection: https://cad.onshape.com/documents/d7aebcbf751ea63aa06fa480/w/d496255ea19f9425bb0ebe6c/e/1fe3d10623afa6ca25027db7?renderMode=0&uiState=674cbf5cb61a7170488c82c5

Re: Dividing the space evenly
In addition to what Simon says, you can do your sketches in reverse order if the holes are more important than the box size. Draw all of your circles first, then make a box that's dimensioned to them. You can still extrude the box, then cut the holes after.
Re: How to make a scalloped cone?
I wrote a feature a while back called Shapes for making things like that scalloped profile. Here's an example of a cone using two of those and a loft.
It's a little less relevant now that you can use variables to drive a sketch pattern, but it's still handy every once in a while as an Industrial Designer. Here's a little gif demo.
Re: What determines when a line can be used as "rip edge" for the flatten feature?
Ok I was able to accomplish my goal by splitting the part via surfaces. It's a lot of mouse clicks and additional complexity but it works. I'm still curious about the initial question. The face split on the top of the loft has been tricky to work around for even less complex darts.
Re: I want to help make custom feature icons
I know, old post… but if you are still creating feature icons… let me know 🙂
Would like one for my Selective Fillet feature:
