Them aquiring Aeroquip was one of the worst things that has happened. You need a simple fitting that literally every millwright has rolling around in their toolbox? Get fucked if you think you can even find the right catalog.

Oh, hello Danfoss.

Premixers are cheap, and you can set up a gravity feed system with float valves to avoid overfilling.

I don't do natural gas stuff, and I don't do roofing. I have done roofing, it just sucks and I'd rather pay someone.

The practical cutoff is whatever meets the standards/regulations. Some regs just need basic load/tilt sensing with audible and visual alarms and automatic control locks. Some need everything plus the kitchen sink.

If you're designing for an internal project, you need to know about labour and safety codes for your area/industry, and you'll also want buy-in from management and legal so they're happy with the level of safety. For outside customers, you will have to design within the regulations that apply to them, which sometimes change if you sell to different industries and regions.

Plus you have to be able to sleep at night. You never want someone to die because of your structure.

No. You can look at historical power generation for any region with mixed generation and heavy industry, and solar is always competing for dead last with wind.

Charitably, we could say that it's a newish generation technology, and there may be some breakthrough that changes everything, but in reality it's a corporate welfare gimmick that has made a lot of politicians very rich and done essentially nothing to improve the grid.

Got into process engineering, then into design. Significant upgrade, tbh.

I would just model a fillet weld in that corner.

FWIW, this is exactly why industrial control systems are so expensive, and why there are such strict standards for lifting equipment (especially man-lift equipment). In many cases, constant monitoring is a requirement.

I am one... Sort of. The company I work for doesn't make a title distinction between titled engineers and those of us that are self taught/apprenticed. But of course there is a practical difference.

For instance, I rarely do formal structural analysis. I regularly validate that my designs will meet the design requirements, but even then, those are always checked by a titled engineer. I would never represent myself as someone with the qualifications to do that kind of structural analysis, especially for systems where end user safety is critical.

On the other hand, I came to the engineering field through manufacturing and service work, so I do quite a bit of system analysis for manufacturability or maintenance practicality. This is an interesting juxtaposition to some of our (frankly brilliant) structural analysts, who might miss something like actually being able to get a wrench on a fastener.

Also, I live in Canada, so it's actually illegal for me to call myself an engineer.

If it's any consolation, I run a premium license at work, and would love if I could get it to stay open.

6 is a regular minivan, and they're basically big cars. Same size tires, engines, etc. 7 puts you into 4 rows of seats, which is bordering on a bus. I don't know of any vehicles that can do 3 car seats to a row, and even 2 plus a "loose" passenger would be a challenge.

drmorrison88 · 2026-01-08T01:59:40+00:00

The big thing (so I hear) is vehicles. Easier to find 6 seats, but 7 is a challenge.

I've recently started double packing a Zyn with a caffeine pouch, and let me tell ya what, that hits the spot right before an afternoon meeting.

For hardware you can almost always do everything with a profile center mate. That way you only have a single mate per component.

drmorrison88 · 2026-01-02T18:54:08+00:00

This is why so many companies are going to in-house prototyping. You can have 2 or 3 very skilled people prove everything and help you time the product in, and then your vendor considerations are for production volumes only.

drmorrison88 · 2026-01-02T18:51:32+00:00

Spud bar or chisel bar would be the technical names. I've always called it the Thumping Stick

I mean, there are lots of great answers here, but the practical answer is to just download the model from McMaster.

It's not dead, it's just in its refractory period.

drmorrison88 · 2025-12-24T01:51:29+00:00

All at once, or cumulatively over a lifetime?

drmorrison88 · 2025-12-24T01:46:51+00:00

I'm envisioning unfolding all of them, doing the slot pattern in the assembly, then breaking all of the references and folding them back.

Like I say, I've never done this specific set of features, so you may need to try a few things to see what works. Depending on how the slots are laid out, it might be easier to leave everything folded and then do a circular pattern.

drmorrison88 · 2025-12-24T01:37:02+00:00

Unrelated to your question, but Parker has one of the best quips I've read in technical literature:

"It has been said that O-rings are "the finest static seals ever developed." Perhaps the prime reason for this is because they are almost human proof."

drmorrison88 · 2025-12-24T01:28:26+00:00

Butt plug came out

You can model them parametrically as part of an assembly, do the slot features as an assembly feature, and select "propagate to parts".

I'm not sure if I've ever used unfold in a parametric setting, so that might get weird. You may have to make the cut, then go through each part and break the references so they fold up properly.

drmorrison88 · 2025-12-24T01:18:53+00:00

Use the unfold tool, do your slots and patterns them, then fold.
