NewFatMike posted:Lmao is there no offline mode? SOLIDWORKS people revolted over it and they added one last year for the 3DX stuff. There's an offline mode but if you're doing anything PLM, it's useless. You have to have everything open and loaded to use it. The model I work in is multiple gigabytes so I just grab a coffee when I load it up. If the Wi-Fi goes down and I lose my credentials, it basically bricks whatever I'm doing. so, I have to shut down and restart. It sucks because I have to hit save on poo poo I don't really want to save just because there's a risk that a single packet decided to gently caress off for the day. The solution is to use Ethernet, but that's not always possible. My model is smaller than most of the automotive models that CATIA allegedly caters to. I don't know how any big name auto companies use this poo poo. My favorite fuckups are when something gets snotty and it decides to crash with the message "an unknown error occurred: error ##### - error." No message as to what it is. Just a generic error with the message "error." I'll try to grab a screenshot sometime Just loving trash all around.

I’m subjected to it routinely. The biggest fuckup is that the big boys are running an on premise cloud and they’re EOL’ing that. On prem is crazy fast compared to cloud, I really have no clue what the hell they’re doing.

Kinda hard to justify billing customers for compute when they own their own machines. Once it's on the cloud, you can start charging per simulation run.

I need a polyurethane bushing design guide. My design compresses the bushing axially, which is probably not how it's supposed to be used, especially with a steel tube constraining the bushing. Do I need to leave clearance for the bushing to bulge? Do I need to rotate the tube 90 degrees, so the axis of the bushing is parallel to the axis of the casters? That seems more in line with how I've seen them used in cars. I am worried I am not loading these bushings the correct way.

Go look at early 1990s mountain bike shocks. My proflex 656 or 959 has "elastomer" shocks which are just like, really soft polyurethane about 2" in diameter with a hole in the middle. It's three discs with two bushings and a bolt down the middle.  You're probably fine with a 1" diameter bushing with a 5/16 hole in the middle?

The bushing currently in the mail are 1.5" OD, 7/16" ID, 3/4" thick. I think Shore 88A. They arrive tomorrow. I note that the bike bushings are not constrained on the OD. That is probably important. I need the tubing for other reasons, so maybe I should bump up the tube ID so there is room to squash the bushing. e: and the bike probably used a smooth shaft, not a bolt with threads. The threads will chew up the bushing, and the steel, and make a terrible noise while it does it. But maybe this is ok since it is not supposed to articulate in normal use. Perhaps the harsh grinding will provide useful negative feedback to the user? (see, now it's a feature) DIY option: cast your own polyurethane bushings. ryanrs fucked around with this message at 05:48 on Aug 14, 2023 |

The engineer brain is unparalleled. I like you and will continue to read this... Frankly... You don't know enough to get this perfect in the first try without empirical testing. And in my experience, a C grade version of this will be good enough that you'll move on to something else rather than spend another hour on it.

I've cast my own urethane body mounts. It was shore 80 and harder than I imagined, closer to a plastic block in my case. I got a small 2 part kit from smooth on. Mcmaster has this nice chart. From how youre talking about the squish, I think you want about 60A. And I'll suggest a design change. This should make the math easier.

I'm late to the party but have an alternative design suggestion: My office's shop has the same issue with the drill press needing to move, but I didn't trust the knucklehead engineers not to crush themselves with a tipping design. Instead I built the press stand onto a flat board with this set of wheels: https://www.amazon.com/Portamate-PM...s%2C181&sr=8-14 Works great, no safety risks.

oXDemosthenesXo posted:I'm late to the party but have an alternative design suggestion: I was literally just gonna suggest that. Far and away the best solution, except maybe for stairs, but just use a friggin hand dolly like everyone else. Thought experiments are fun but this is way too much brain power being burnt on this very very simple problem. This is one of those cases where you just overbuild it and get on with your life. If you don't use the above suggestion then you just need to cut, fit and drill one piece of 1/4" web structural angle and send it. I mean, you could probably just drill holes in the back face of the base casting and bolt the casters directly to it through two of the four mounting holes and it'd still work better than anything you already thought of.

The drill press needs to be a walker bot like Chomp from Battlebots evolved into. They get 500lbs (double weight) for being walkers. https://www.youtube.com/watch?v=lGCnHN983q0&t=100s Get that drill press into the ring!

So I signed up for the $10/mo SolidWorks Makers offer because I want to learn a little more and $10/mo is a pretty good entry point. I have also always had the idea to fully 3D print a Settlers of Catan set (minus the cards, obviously). But I also suck at art. So I settled (heh) on a generic aesthetic. And when I say generic, I mean like the classic unbranded items that we see on shelves in movies and TV (I honestly don't remember if that aesthetic was ever real) with just black lettering on white. I have number tokens and printed my first 'WOOD' tile last night. This is that tile with a number token from the 5-6 player set. It's silly, but I actually really kinda dig it and I'm considering putting it up on my Etsy shop.

Anybody have a Canadian SW vendor they recommend? And will they license it to us for just a month or two? We don't normally do enough mechanical CAD stuff to warrant SW- I make due with *spits* alibre, it's honestly fine for 95% of my work (doing in-house parts, jigs, custom organizers and toolholding racks, etc for a dental laboratory) that just needs a robust basic mech CAD functionality, but I'm designing a whole lab's worth of bespoke workbenches and machine enclosures using aluminium extrusions, and Alibre's very rudimentary assembly + parametrics functionality just isn't cutting it. I desperately need Misumi's design library and a real assembly functionality for this, but I don't think I can get them to spend more than a grand or so on it. Completely unrelated- Alibre on a resume doesn't mean anything, but SW definitely does.

Phone posting but I swear Misumi has online configurators you might want to use. I remember configuring an entire rectangular prism in extrusion that includes brackets and hw into one part number after seeing a banner ad about it. I don't have personal experience with their extrusion but something like that would simplify things.

Does anyone have a recommendation on an easy CAD program if I want to create a basic frame made from extruded aluminum (aka 80/20 profiles) and get a list of lengths / quantities of all the parts used? Solidworks seems like overkill (plus the UI loving hates me specifically) and the auto-quoter tool that 80/20 has on their site looks ancient. Something where I can physically drag out parts like brackets/fasteners and have them snap into place would be nice, maybe something like Tinkercad? edit: Whups, seems like by coincidence you folks were already talking about this, with regards to Misumi?

Onshape works for figuring it out at least, and you can get the profiles premade, then you just specify the lengths and mate ‘em as needed. It's not a wizard like what it sounds you're after, but this was super painless and cost exactly $0:

OK thank you, finally something where a caveman like myself can just instantly drag poo poo into the field and it knows how to snap the items together. Well, mostly, for some reason it added this fastener at some insane orientation, but otherwise great so far:

I haven't seen that site before and I'm interested in your experience with it if you end up using it. We use TSLOTS at work and we have a bunch of templates, macros, and a library of standard parts. Most of the parts auto mate with mate references and the template/macro combo makes the BOM TSLOT readable. I leave stuff like that crooked screw as it lays. I argue it still makes an accurate BOM and the assembler will know how to put it together. My time is too precious for that kind of work.

I've grown to enjoy using the Solidworks connected as they have continued to improve it. Offline file storage was made functional, licensing was broken enough to let me use it offline. The background license client even seemingly improved to only asking for password daily instead of what seemed like every time my pc slept. That being said I cancelled my subscription as for the second year in row billing was magically charging me almost $800 for a $99 listed cost. I waited a month and repurchased at the correct price.

Jesus fucken Christ what The improvements have been steady — they published a bunch of posts to the CAM program which is really nice. It’s still not very polished, even on the commercial side. It’s kinda fun watching the SOLIDWORKS and CATIA guys throw blame back and forth about it. I oughta set up some YouTube videos about how to invite people to your platform so you can collaborate on projects. For some reason, Makers licenses aren’t set up for that automatically.

I'm really liking the program, I've been making everything accurate to the millimeter pretty easily. It seems to even make some correct guesses about which way to rotate profiles when I duplicate them. The crooked screw thing, the problem is it seems to be doing it with literally EVERY fastener, and it throws a poo poo fit about the parts being in collision. I sent an email to support to see what they say about that.
