Check out a tutorial on SOLIDWORKS weldments- it has a full tool suite for exactly this kind of thing. Might be worth trying $10 for a month to check it out. It’ll even spit out a cut list for your chosen tubing/pipe size so you know what and how many to cut. Other useful tutorials might be for 3D sketching as well. lol Biracial and I on simulpost - yeah it has full SOLIDWORKS professional tools. So sheet metal, weldments, mold tools, I think even some MBD stuff is in there. All that stuff is part of SW Standard.

the "what a stupendously bad idea" is sinking in, degree by degree, oof + thanks pals biracial bear for uncut posted:Are they not considered waste if they're just laying around/not stored properly? afaik 'nuclear waste' is a byproduct of nuclear industry or isotope preparation, overwhelmingly low-grade contaminated secondary materials or end-of-life fuel that no longer requires cooling, while uncontained + unaccounted radiological material (the primary radioactive material itself, generally hot and acutely-hazardous even with brief exposure) is an 'orphan source'. nuclear waste can also constitute an orphan source if it's hot and has gone missing, but that isn't the usual understanding of the term

biracial bear for uncut posted:Are they not considered waste if they're just laying around/not stored properly? I guess the canister could itself count as nuclear waste if the source has decayed to the point where it isn't useful to anyone anymore. But the point is the capsule is not a container expressly for nuclear waste. When new, it contained a brand new radioisotope manufactured just for that purpose in a nuclear reactor. Ambrose is right that the correct term for a radioactive object that's lost, stolen, misfiled, or otherwise not under control is an "orphan source."

DXF is an amazingly terrible format for something so old and fundamental to the industry. It seems like every single time I try to use it, something gets hosed up. The scaling is wrong or some parts are missing or distorted or it's incompatible because AutoDesk keeps changing the spec or maybe something new I've never seen before! I hate it Meanwhile the chad Rhino: just copy those shapes in Illustrator and ctrl-V into your Rhino document. It'll paste them as properly scaled vectors onto the active construction plane. shrug Sagebrush fucked around with this message at 22:56 on Feb 10, 2022 |

turns out if i just never turn my computer off or quit (or crash) solidworks, i can skate on last year’s license clear into mid-February. knock on wood. i really gotta get around to upgrading to the maker version, is there a breakdown of the substantive differences between the two? are the parts you make still version-locked to prevent the Pros and the Proles from commingling their files? if i’d like to continue doing commercial/paid/freelance work using SW into the future, is the maker version a nonstarter? i’d be willing to pay “more than $100/yr” for actual proper solidworks that produces files that are fully interchangeable with other people’s poo poo, but i definitely cannot swing paying for a real deal Full MSRP Commercial License Ambrose Burnside fucked around with this message at 00:01 on Feb 12, 2022 |

I haven’t tried recently, but I don’t believe the Makers version SLDPRT will open in the commercial version. STEP export and all that still work (heck even .prt, but I’ll have to check), but I know it’s not the same. There is the Entrepreneur program, which is much less expensive. It’s intended for folks with a particular product, which your projects might work for. Eventually you pay for the full license, but if you’re trying to ramp something up it could be good. If you want to spitball some stuff, shoot me a DM. I might have a tricks or contacts.

Okay so professionally I use rhino 5 with an add on package that is no longer being updated. I’m going to end up getting rhino 7 and transitioning to it because of the lack of updates to this specific add on package. From a hobby perspective, I have used a variety of free programs and :files: but preferably I’d rather not do that. Honestly I love rhino, 7 seems like it has a lot of great features and the workflow seems to work for me. The price fits my budget. My only issue is CAM. There are opportunities for me to start learning some milling and CNC stuff at the local makerspace, plasma cutting, things like that. Does anyone here use rhino and CNC together? Do you do your CAM workflow on another program? Trying to get ahead of it as I start learning

If you're at all cost-conscious, Fusion 360 is the only way to go. You can export all of your Rhino stuff as STEP files and machine it in fusion no problem.

I would also say that if your makerspace has CNC machines with tool changers that free Fusion 360 will be a massive constraint - having a single tool for your CAM is massively annoying. Having a separate CAM program is very common, so no worries about that. Are you using a Windows computer? If you’re using a Mac, your options are pretty much either Fusion 360 or MeshCAM. If you’re on Windows, there are a lot of options. I haven’t gotten access to the CAM included in 3DX SOLIDWORKS for Makers Offer, but it’s been around for a long time as the CAM solution in CATIA, and there’s a solid training video series on it provided by Dassault. That one is $10/mo or $100/year which isn’t bad. Unfortunately you can’t split out getting the CAD stuff from it, which is the majority of what they’re charging for. Additionally, it might be worth checking out RhinoCAM. I don’t know anything about it, but I do appreciate having the option of using CAM in my CAD environment: https://mecsoft.com/rhinocam/ Your makerspace may also have some CAM licenses in house, and if they don’t but are interested I’d be happy to help them find some good solutions - they’re out there, but you need to know where to look. There are often discounts for that kind of thing.

If you’re a student the Fusion liscense is free for 3 years (even if it’s been a few years you can usually swing the liscense) and IMO the fusion CAM kicks serous rear end (I’m a prototype programmer and machinist at a medical device company for work. We do not use fusion but I wish we did)

The fusion cam kicks rear end because it is actually HSMworks integrated into fusion 360. HSMworks is the actual best CAM software there is, but it requires a SolidWorks license as well.

Yeah, but if you're getting Delmia's Shopfloor program already with the Maker's Edition of Solidworks, you might be better off going through the tutorials for that anyway if you're going to be learning a new CAM software. That's like, "experience learning a CAM software used by huge loving design and manufacturing companies" CAM. Think Boeing and General Electric big (though they also use MasterCAM and probably also Fusion360 in different divisions because they like to diversify everything or get software packages recommended by machine manufacturers--that's how my current employer ended up with AlphaCAM way back in 2008). Granted, not everybody can get a foot in the door at those companies because they have a pretty stiff list of pre-qualifications to apply for certain positions (industry gate-kept certifications, etc.), but I figure if it's something they get good use out of it ought to be good for hobbyist use cases, too.

Oh yeah, I’m just saying that if you’re coming in with a favorite, it’s there. My work is asking me to be an SME on the DELMIA NC package that Shop Floor Programmer uses, and I’m pretty amped. It comes with machine kinematics and all kinds of fun overkill things for the Makers Offer that I’m really psyched to play with.

Thank you! Unfortunately to the other poster I am not a student, but I am on windows! My rhino add on package doesn’t work on Apple so that basically locked me in. I’ll check with the makerspace and see what’s up. My guess is they have some sort of fusion 360 license, but I do know for the plasma cutter you need to come with a specific file ready (which I should figure out). I definitely know we do not have any CNC machines with tool changers as everything is fairly basic. Is fusion360 still free for hobbyists? I had it back when it was free for makers but when they announced it switching to a paid license for everyone I was put off by it. I’ll check out rhinoCAM!

It’s free but substantially limited - if you’re just using it just for single tool CAM stuff and your CAD in Rhino, I can’t really conceive of a really limited situation with that workflow.

RhinoCAM is a very serviceable CAM software for general use, can't remember how much it costs but I've used it at a previous job and it did a very ok job. We weren't doing anything super complicated but it did fine for 2.5d work and basic 3d stuff, I don't think it has any of the rest machining or adaptive or HSM toolpath stuff but tbh I wasn't doing that type of work when I was using it so it might be there and I wasn't aware of it. I liked it because doing CAM in you CAD package can be a pretty straightforward way to do things and I thought the rhino drawing tools suited themselves well to constraints and boundaries for toolpaths whereas I find doing all that it parametric and associative CAD programs kind of a pain. I'd encourage you to look at it at the very least.

Looks like Fusion 360 is changing CAM...again: https://knowledge.autodesk.com/supp...-Extension.html  tl;dr 3+1 and 3+2 tool axis orientation is moving to the core version, and 4 and 5 axis simultaneous milling is being taken from the core version to the machining extension. I'm not sure how much of the core version is in the free version, but I thought it was worth posting here nonetheless.

There was some fun speculation about this at work, so I thought I would share here: Apparently, Autodesk and Module Works struck a partnership deal a while back, which seems to indicate that they are going to be getting some new features in Fusion 360 CAM which are similar to some of the higher end features in CAMworks and others. I’m not sure if that’s automation or efficiency capabilities, though. I’m not very familiar with MW and what they bring, so I’m curious if anyone has any insight: https://www.autodesk.com/products/fusion-360/blog/moduleworks-partnership-announcement/

My contract engineer is running an FEA in Solidworks , but he said the spec sheet I gave him didn't have Young's Modulus for some foam of a certain density. The manufacturer said "our spec sheet uses Compressive Modulus to mean Young's Modulus, that will work". My engineer says "Compressive Modulus is not always the same as Elastic Modulus, which is what Solidworks uses to mean Young's Modulus". Who is correct? Apparently the FEA renders now by guessing that value from similar materials at Matweb.com, but it is the last value we need to have precise for an accurate simulation. If I nag the manufacturer's engineers for more data I don't want to sound like a doofus.

NewFatMike posted:There was some fun speculation about this at work, so I thought I would share here: And the other post too. Fusion sucks at anything beyond 3+2 ATM. I've got the machining extension at work and the best thing it adds is tweaking the angle when setting tool orientation. Without extension you need a feature to reference or a sketch plane or line to represent z+ With the extension you can use the above and then rotate or type in more angle manually. Even at 1k+ per year it's useful enough to buy. Edgecam wanted 2k per year for maintenance. Plus 10k for the base program and 5k for a post. The only functional useful simultaneous multi axis it has is rotary which is basically parallel but the extra axis spins. Hopefully the new partnership adds some more multi axis stuff and it's all from one extension and not some EA level buy our 6 hour booster.
