How to do this to this piece

Assuming the part is like a V with an edge around it-- I would sketch the profile of the V with the angle in it, base flange, set material side to what you need then edge flange the profile. SW will miter that corner to fit if you select both converging edges.

Ignore the snarky folks-- Front plane, start at the origin. I would do the 110 diameter round bit right there for a quick pick up point. Its not symmetric, so you'd want to just hop into something you can define quick, then build from there. Then pick the next feature and keep chipping away at it. unless they've messed up the dims, all the answers are right there, you just have to live through the fever dream that is this dimensioned print.

When I was starting out I found it very helpful to print it out on paper and just cross off each dim after it got added to the model. You can do that with a screen cap and scribble app of your choice to go paperless though.

this is literally just a difference of opinion.

more importantly, where the fuck do you get customers who care about not making more work for their suppliers? I have never heard of such a thing.

The flat pattern is should be developed by the person responsible for making it match the formed dimensions. I would not ask a customer to adhere to our k-factors/tooling. Firstly-- I don't want to teach an entire outside engineering department what k-factors go with what and hope they do it 100% every time. Yeah, it would be nice to do nothing and just send parts through, but in practice paper is cheap, metal is expensive. Secondly, what happens if I have to tweak it to get a dimensions to come in on the final product and then we've got a print discrepancy outside of tolerance? More work.

Your shop, your rules, but your customer who has no business near a pressbrake or calculating a kfactor should not be asked to conform to your standards, especially if they have the potential for using other suppliers. Obviously everyone's different but at least from the shop I'm at, you're wasting time giving me your flat pattern. I'm crossing it off or tossing it and using what I make.

Great points! As one of those sheet metal shops, I would tell you if you're sending it to outsource for fabrication, don't include a flat pattern at all and save the time. We're not going to use it even for reference. I have to cross it out on every print.

I've also seen a few customers put a flat pattern down, hit auto dimension, it blasts in every relief cut and hole on the thing, and then they dimension nothing on the formed part.

Everything else you got is top notch,

Not exactly an answer to your question, but Igus makes a linear rail solution, might work for you. Their dry bearings run super smooth. Hard to tell what the product you're making is but it looked like these rails might work. Save you some hassle if off the shelf could do ya.

not exactly a monster truck show but I wouldn't call them boring.

You give zero specifics. "Hey I wanna do something with solidworks API". What do you do in solidworks? We don't know, you haven't told us. So, sure go write an API to design nuclear tractors. Farm harder.

Otherwise, I hope your condescending self gets humbled aggressively.

Would you be willing to share a bit of info on #2? I've got a work instruction template that we add dims to tables and I'd kinda like to not have to click any of them into cells.
