NewFatMike posted:The thing that separates good from great designers is how little breaks when you have to change something way upstream! This is what really makes a person productive. When I first started I made some lovely stuff, moved one component, and watched it all fall apart. The real difficult part is understanding why you shouldn't project that hole or reference that corner when it seems like the easier thing to do. You look like an amazing wizard when someone comes in and says "Yah, so just move all of that poo poo another 3 inches." and all you have to do is extrude one end and it's all perfect.

I use Fusion just often enough on complex assemblies to be able to do it, but not often enough to get really good at it. I'm getting better, but I've absolutely run into situations where it was easier to tear it all down and start from scratch than deal with the ghost dependencies in a hole pattern or something. A style guide, or some such, would be awesome.

Here's the thing: You can copy a component and then "Paste New". It will then be independent. I've run into issues if you just have a body and not components, specifically you can't do joints with bodies, but you can with components.

biracial bear for uncut posted:EDIT: Yes I know it's possible to start in the Drawing part of Solidworks and just draw whatever (and eventually take that data and make a model later if you want to) but that's a whole different course and a much clunkier way to do poo poo than learning how to model. Excuse me sir, the drafting class is down the hall. My grandfather was at an auction 10 years ago and called me saying he bought me a blueprint plotter. So I'm thinking a digital "plotter", instead he arrives with gallon jugs of chemicals, light boxes, large trays, and then I realized it was actually for making "blue" prints.

biracial bear for uncut posted:This was back in 2016, but still applies. For production parts we use Draftsight almost exclusively. But we strictly do grinding and plating with a touch of lathe work. On top of that we normally re-draw the customers prints to our own internal drawing so that they sign off on only the needed stuff. So for us a 3d model would be overkill. Now for any tooling, maintenance, machine layout, I use 360. 2d cad has a place, but it's becoming the niche, and not the norm.

I'd love something that will just generate a reliable cutlist without me having to put all the dimensions in the part name, tbh. There are some plugins for Sketchup that do this if all of your cuts are right angles. I think some are designed to export into CutListPro or some such program. I didn't pursue it as all of the cuts on my most recent project are not right angles and it's like $2,500 a sheet so I did it all like a giant stupid jigsaw puzzle in Draftsight.

honda whisperer posted:One place I wish fusion spat out canned cycles is for the lathes. All our lathe guys have way more experience with and prefer the way it's done at the control. 90% of the time it's fine but one has live tooling and can mill and another is a twin spindle multi axis with live tooling. I think it does? But if I recall right it's finicky as to features, you can ask it to make canned cycles but if there is something outside the scope of the canned cycle it just won't do it, nor will it tell you why.

cruft posted:Does anyone here work with physical gizmos enough to have advice on this? I might try printing it sideways to see if it runs smoother, or maybe just sanding the pieces would be enough. But I'm hoping that someone who doesn't blow goats when it comes to mechanical design can toss me a few pointers on how to improve this. You're trying to get a slip fit which will be challenging with short throw switches. Another potential difficulty is roundness of the two parts. A good, non-3d printed example is an industrial push button. They have a bore with a fairly tight fitting, smooth, shaft. We have high cycle machines at work and even with a ton of lithium grease that bore wears out and the button sticks. There are a lot of places that friction or poor fit can seize up your mechanism. One spot I'd look at is adding a second tab for support so keep it from moving about the axis of motion. I'd do it on each of the switch arms.

Normally everything I do is joined, but sometimes it's nice to move it, see how it looks, move it, etc.

Process question in Fusion. I've got an assembly with about 100 different components. There are a few mounting plates that have evolved as the design has, but the plates are still present. Maybe they have a new notch, or a hole, or whatever. But certain things, like a bearing block, were inserted when it was still design 0.1, it's now design 336. I just changed a hole size that was referenced off that bearing inserted at design 0.1 and Fusion flips the gently caress out, re-renders back to design 0.1, then has to rebuild everything once I finish. There's a cascade of warnings as a bunch of poo poo isn't there anymore. It feels wonky and like I'm doing something wrong. Am I missing something?

We just commissioned a machine today that I designed in F360. Really cool to see it go from start to finish and have someone operating it. I worked with two other people who are both machinists/fabricators and it was great to model a bit, animate the movements, let them push and pull slides, and get instant feedback. I sourced so much stuff from McMaster just because I could drop it into the model without doing the create an account, download, unzip, upload, convert dance. I had some serious anxiety that some components wouldn't match, but they did. Every single time. I was curious how other folks are handling revision control in 360? Do I just 'save as' my production models and work off a revision folder?

It's a really awesome moment when someone is like "hey, can you make that piece wider?" in a really complex assembly and your constraints are done well and the model grows perfectly. Of course there's another moment where the constraints are done wrong, the joints are all stupid, and the model goes into gently caress gently caress land. You all know what I mean, the CAD kaleidoscope of incompetency.
