Re: Custom Feature Part Name (Ovyl)
Wow I never thought anyone would hit that limit haha. I'll take a look when I can. You might be able to work around it for now by getting more than 1 out of a segment using toString() functions and ~ for concatenation. You can also stretch the feature UI wide to have more room to read since it will become long.
Re: Custom Feature Part Name (Ovyl)
You could rework the feature to use an array parameter instead - unlimited segments that way.

Re: First sketch, only 1 square and still not defined
If the sketch lines are blue, they are undefined. Meaning they need dimensions or constraints for their size as well as their position. You can constrain and dimension to entities within the sketch or outside the sketch as an external reference.
If you really want to become efficient at Onshape, complete the Onshape Learning Pathways. They are amazing.
Re: How to make a cube?
I'm curious about the use case for this workflow. What are you trying to achieve? Draw.io is neither very accurate nor overly comfortable to use, so this would only make sense if you absolutely need to incorporate geometry provided by someone else into your designs. I could imagine placards, type or serial number stickers or other graphic elements.
I ask because I have had similar cases, though not with Draw.io but other graphics apps.
Re: LiveWorx ???
I don't know, what do y'all think? Would there be interest in having an online meeting? Do you have other ideas?
Re: How to make a slotted hole
With help from my friend Cor van Doorn, I have it like I want. Had some error messages like 'not completely regenerated' and 'undefined' but now understood their origin and solved them. I also understand why all elements have to be constrained to something, that was a new concept I needed some time to grok. Onwards, always onwards!

Re: Projecting a 3D part onto/around another part's face
@S1mon That Deform tool is much like Rhino's Flow Along Surface which can be extremely powerful for certain things. Good to know Parasolid can handle it! c'mon Onshape devs! Christmas is coming 🤞
Re: Projecting a 3D part onto/around another part's face
Plasticity can do some amazing things with "unwrap" and "deform", but it does have some challenges with more complex geometry.
If your main goal is to use an image to create geometry, you might want to do that more directly in Rhino (possibly with Grasshopper) or there's an old windows app (free) that may work.

Re: Boolean Boss Battle
When you see references to self intersecting… this is one example of how that happens. Depending on your geometry OS will not know how to resolve things and calls it self intersecting. In this case its just the inside radius that's an issue. Making the radius bigger resolves it or if it were square cut it wouldn't be an issue. sometimes you might have to apply two radii after an operation like shell or thicken to get your desired result.
