    Industrial practices in CAD modeling of machined parts

    After I think 18 or 20 years of solid modelling, I'd say 'whatever it takes' to get the net shape you need. I've been working a lot with castings lately. Generally with castings, weldments too, you make an as cast or as welded configuration, and model the machining steps that remove material in...

    Boeing again

    3D, when I was in school, my controls professor said in lecture that he was working with the navy. They wanted a smoother ride on the automatic carrier landing system so that the pilots would use it more often.

    Boat steering

    Could you develop the mission better before detailing the boat? You might ask what someone will need to self rescue when your device comes up to them. You might also take a look at what other people have developed for similar missions...

    How to Fix Broken External References

    My guess is that you lost your default search locations when IT worked on the computer. If you have references in different locations it'll be a mess until you tell SWX where to look, then it should be fine. This is useful about where SWX looks for references in what order. You probably lost...

    Destacking I-Beams

    At the boatyard, we have a 1/2 ton chainfall on a trolley and a chain that has a ring in the middle and a hook on each end to pick and move the steel. Once you pick it, it's not hard to move with the trolley. I expect with a crane that has a rotating beam you could use a chainfall or hoist on a...

    Hertz selling off EVs due to higher repair costs

    I don't think it's because the EV's are electric, but because the cars are made by companies new to the auto body business. https://www.theautopian.com/heres-why-that-rivian-r1t-repair-cost-42000-after-just-a-minor-fender-bender/

    Structural Drafting - Software Recommendations

    I think 2010-2012 or so was the last 'unplugged' version of ACAD. Now it needs to phone home for license verification pretty frequently if not always.

    Seeking a sane explanation for NEC 110.14(C)

    An electrician friend explained that when capacities of conductors, terminals and so on are mixed one can form a wrong idea about the circuit based on incomplete inspection. If incomplete inspection leads you to unsafe ideas about the wiring, then that's the problem.

    Weldment Cut list for selected bodies

    Can you hide the unused rows after ballooning the items you have in the view?

    Printed House (Concrete) failed in-situ strength tests

    That's interesting. They might have to change some things, but I wouldn't stop trying. Maybe they didn't strength test at proof of concept or proof of process capability when they should have. King Arthur didn't stop when John Cleese said 'Your mother was a hamster and your father smelled of...

    Composite stuck to mdf mold

    Depending on the coefficient of friction, is your 11° draft self-locking if you have a residual force between the mold and the part?

    Composite stuck to mdf mold

    Maybe if you vent extreme points of the cavity or blow with low pressure air?

    Tourist submersible visiting the Titanic is missing Part 2

    SWC, Does the radial force gradient cause any trouble with a high pressure vessel like that? You have 5ksi radial at the outer surface and practically nothing at the interior surface.

    Tourist submersible visiting the Titanic is missing Part 2

    SWcomposites, I remember detailing a fabricated steel beam and digging thru my omer blodget book and my structures book to find the shear at the web/flange transition, checked it twice and was like, Oh, I'm not going to get a welder to lay down that little metal, am I, and spec'd out 2" in 6 or...

    Opposed piston swashplate motor - INNengine

    That reminds me of the engine that Rodrico developed here a few years back without the extra compression/expansion stage.
