I was drawing up a simple part yesterday and decided to do it in Rhino because I already had it open and it was fine for part design but making a drawing for it sure had me missing solidworks, all those automated tools sure are nice.

What is a good resource for free 3D models of stuff? I'm talking about basic widgets like toilets/sinks/tables/chairs etc. Household sort of junk, obviously not needing to be high quality, just good enough for general layouts and whatnot. Also stuff like generic fasteners would be nice, but I suppose I could grab those off McMaster or something. Preferably in generic formats that FreeCAD can take (IIRC STEP and IGES)... last thing I tried to import I ended up having to run through SolidWorks first. I'm sure this has been asked/answered but I looked around and wasn't able to find anything. I hate googling stuff like this because it's inevitably 1 good link hidden among a thousand scam sites.

GrabCAD and 3D Content Central are my go-to sites for that kind of thing. It's all models folks have made themselves and uploaded, but it's handy. Depending on what you're looking for, sometimes you'll get supplier models. Both sites require accounts, so hopefully that's not a deal breaker.

Awesome, thanks! Creating an account isn't a big deal as long as I get something out of it. It's just trying to find a site that is actually useful without having to wade through a dozen SEO sites that promise the moon and end up being junk after you jump through a dozen hoops.

I've got a million personal SW designs I'd like to start publishing on grabcad, thingiverse etc, but I wanna be sure i'm not including my real name (which is associated with my software key) or other sensitive metadata in the files- how do I go about this? I've never had to share anything outside the company so I've never had to worry about this before. For SW working files, primarily, but .stls and the like too- I've got no idea how metadata works with those at all.

Hmmm there might be some of that in the SLDPRT properties - if you want, I'd be happy to take a look to see if it carries over. Generally a STEP file won't carry any metadata, though, if you would rather go that route.

I think I got it figured out; might take you up on double-checking the metadata for part/assembly files soon. Another question- is there a way to publish a bunch of part iterations at different scales, but driven by the final part mass? As in, I want to generate 5/10/15/20/25/30/40/50 gram versions of a part, can i do this by directly entering the weights i want vs my current approach of playing with the scale to ballpark each part's mass, one by one?

You ought to be able to override mass properties in different configurations. Nothing about the design is changing, right?

That would seem like a fairly advanced application of global variables/etc. and I'd be interested in seeing some screenshots of how you set it up if you get it to work.

If you're just scaling the part up and down, I don't think you need to use global variables at all. Double the scale should be double the mass and so on. If you are trying to change one specific feature to adjust the mass, that's certainly more complicated. I don't know if the part's mass can be an input into the equation editor. However, you could do it manually if the changing geometry is simple enough. Say you're making a simple barbell with cylindrical weights. You start with the bar and calculate its mass. Then decide on the diameter of the weights on the end. Create a global variable for the barbell's total weight. Create a feature of the proper diameter for the weight, and set its extrusion length with the following equation, assuming I got everything right: L = (desired mass - bar mass) / (4 * pi * r^2 * rho) where L is the length of the extrusion, r is the weight radius, rho is the density of the weight material, and we assume there is an identical weight on each end.

I gotta stop answering questions before coffee because I got the totally wrong read on this. I know there's a workflow with Simulation Xpress if you have Premium (educational or otherwise) that can do goal seeking functions. Do you have a screen grab of the part? I know there are other goal seeking functions you can do with SW, but I haven't had to use them. If the part is pretty complex and the above solutions don't really work, I can ask around.

Sagebrush posted:If you're just scaling the part up and down, I don't think you need to use global variables at all. Double the scale should be double the mass and so on. Yeah, but if you're wanting to semi-automate it you'd have to find a way to reference the mass in a formula that then re-scales the entire object based on your desired mass. I'm trying to think of a way to do it that doesn't involve circular references, but you'd basically have to make a Global Variable that is set at whatever scale value you need to make the part your baseline mass value, and a separate Global Variable that is the baseline mass itself. After that you either create a design table and populate it with rows for whatever mass values you want and formulae to apply a final Scale feature to the entire part in each configuration the table generates for a given mass value. I'm can mentally picture how I'd do it, but I'm having trouble thinking of how to word it that isn't circular in the explanation.

fwiw i’m designing multi-part casting molds for fishing sinkers/jigs, so we’re talking about spinning off maybe 6-12 sizes for a given design, almost always a simple uniform scaling. i have two molds i’m working on currently so it’s not actually onerous to tweak the scales by hand as it stands, but if i start doing this in earnest i’ll definitely need to sit down and streamline this particular aspect.

If you're going to be doing this kind of thing a lot, it might be worth checking out the Driveworks Xpress tutorial in case that works better than a design table and configurations. Looking through the help files, I think a Design Study is what you're looking for.

I'm looking to get into some more organic modeling, and trying to decide where I want to spend some time learning and expanding my skillset. The primary use would be for designing medical models for patient education. Some aspects would need to be dimensionally accurate (mounting to displays, integrating with mechanical components), but the majority of it would be less constrained. Some parametric design capabilities would be nice for my sanity at least, as well as things like interference detection and maybe limited motion modeling. Animation and fancy renders aren't important to me. Output would be for 3d printing for eventual casting and molding at small-medium batches so the ability to handle scaling for shrinkage/etc would also be nice. I have ~a decade of experience using solidworks for functional mechanical design. I've barely touched its surfacing tools, though. I work at a university, so have access to academic pricing on most software. We're somewhat budget constrained at the moment but can handle some limited expenditures (non-subscription, ideally). Initially I have been looking at Blender and Rhino3D, with a slight tendency towards the latter but not for any specific reason. Any other packages I might want to look at would be welcomed, and if people with experience using both have commentary about which packages might be better suited for my needs, I'd love to hear more.

Imo never surface in SOLIDWORKS it's loving miserable and models come out like poo poo. Blender and subD modeling is a little easier to do but harder to.get exact dimensions, rhino and surface modeling will have a higher learning curve but better dimensional control and accuracy. The subD tools in rhino 7 might be the ticket for you but I haven't used them personally.

They mentioned needing dimensional accuracy and in my limited experience getting dead nuts on even simple dimensions can be hard due to the smoothing in subD modeling, you'll get ballpark easily but anytime you're working with meshes that are being smoothed you end up with weird dimensions in unexpected areas.

If you need both mechanical precision and smooth freeform shapes, you are pretty much stuck with NURBS. The Rhino subD tools might do it but the gold standard is still plain old NURBS surfacing. Unfortunately that is probably the hardest kind of 3D modeling there is. But that's what we've got. Get thee a copy of Rhino and buckle down!

The rhino 7 subD tools convert back to NURBS which is the nice thing, you can get it close with subD and then pull sections and isocurves to use as a base when you adjust dimensions for final surfacing without having to deal with the bullshit problems of actual meshes at any point

Signed up for the Solidworks 3dexperience for makers. The web interface is confusing as hell, there is a specific server you need to login to to get your personal dashboard and not some bizarre linkedin knockoff with built in marketing buzzword selector wheel. Downloading the 14gig installer for the "3dexperience Solidworks Desktop" now and hoping I didn't waste $99.

What the gently caress? That's a full month ahead of when I was told it would be out :v I have an onboarding document for my makerspace if you want to see something a little more helpful than whatever it is I am sure they are sending you. I specifically reached out to the guy in charge of this to help with new person onboarding because the 3DX platform is a dumpster fire. Shoot me a DM with your email if you would like that PDF! It's primarily geared towards the browser-based stuff. The SOLIDWORKS Tutorials are surprisingly good and cover a shitload of stuff:

Well, download failed. Can't resume from Firefox and clicking on the link in my dashboard broke. Navigated away and now my dashboard is all changed and I can't access that download page anymore. I think you might be onto something with that not supposed to be out idea. Edit 1: Now using their launcher installer from the app pane instead of downloading a huge ZIP. It started a progress bar like it was opening and now is sitting there in the background inaccessible doing nothing. There is something in the taskbar but it only seems to be able to open a browser to the useless web interface. Hahahaha wow. Edit 2: The sneaky hidden launcher claimed it would stop the download and lose all progress when i tried to close it. So I am just going to leave it for a day and test my luck Commodore_64 fucked around with this message at 23:04 on Jul 28, 2021 |

So with 3dExperience Solidworks for Makers, you can save local files with the same extensions as commercial SW, but guess what, only SW for Makers can open them! You have to use a metadata free interchange format to get them into the pro version. I'm not sure what I was expecting, I mean you can't have commercial users just using the cheapy tool. Also I made some parts and have no idea how to get them to save to my cloud lol. Edit: Had to install their drive app. Not sure how I was supposed to know this. Also it took `5 minutes for it to react to clicking to install it from 3dx we control panel. What a joy this platform is. Commodore_64 fucked around with this message at 19:43 on Jul 31, 2021 |

Yeah, if you can't share files and there's no CAM. If you're on Linux or Mac, I'd recommend the Makers version for the browser based bits. Still waiting to hear back from the folks in charge of the actual program to figure out what's up with that.
