Why didn't you ask in the thread you stole that gif from, OP?

Just for that, I'm not telling! Also because I'm on the toilet and the links would be on my desktop, but mostly because of that.

>>32700641
OP, do you think you could make a helical AK mag in CAD for /k/?

Which CAD program is typically used in the USA?

>>32701479
CATIA, Solidworks, Inventor are probably the biggest ones. Inventor is really popular with smaller companies because it's cheap. I like NX, personally.

Does anyone here play world of guns gun disassembly? I love looking at the mechanics and seeing how a trigger pull ends up firing the round

>>32701548

This. Don't forget basic AutoCAD for 2D work. A lot of smaller companies can't justify the cost of a full 3D suite of software.

I was ripping models from World Of Guns: Gun Disassembly. I used Ninja Ripper. I had to assembly the jumbled pieces together back together in 3DS Max.
The model isn't very high poly and I want to make a reworked version in SolidWorks. I'm very novice with CAD software and so far, I only made a gas piston that probably has incorrect dimensions. The original model looks pretty poor to use for CAD. I'd need real schematics or measurements to clarify and get a more accurate model.

>>32701486
Glad to hear this, seems like there isn't much difference to Germany then.

I learned Inventor in training and I'm learning CATIA at college right now, although they want to switch to NX. Overall I prefer Inventor for now, especially the interface.

How does NX compare to CATIA and Inventor?

>>32701599
With my basic skills, I made the gas piston from the measurements that came from the model. I had to eyeball the curves.
Mostly just extruding and chamfers... I don't know how to do more complex shapes (i.e the bolt/bolt carrier geometry)

>>32701627
The modeling itself is largely the same but the built in simulation in NX is very far superior to, say, Inventor. It's also multi platform, though the Mac OS and Linux versions are gimped.

>>32701643
A smarter way to do a cylindrical object like that is to draw the profile and revolve about a centerline or axis. This cuts your 10 separate extrude operations down to a single operation, resulting in a less complicated model. Looks good regardless.

Whats the best way of getting really good at CAD? I have a basic understanding of SolidWorks and Fusion360 and am going to learn ANSYS soon. What are the best online resources for learning this quickly? I'm a mechanical engineering major and want to build a virtual portfolio of CAD and simulation work to show potential employers.

>>32701647
Sounds good.
How about technical drawings, is it more like Inventor or CATIA?

It bugs me that I have to manually put and adjust my text in the title block in CATIA, while Inventor has an extra window for this where I can quickly write everything down.

>>32701902
The best way would be searching for associate degrees offered by your local community college. Otherwise, there are hundreds of tutorials on YouTube but advanced modeling may be trickier to learn on your own and it's going to take hours of practice.

>>32701998
I guess it's reminiscent of Inventor, but there's a lot more you can do with the drafts. I'm really not familiar with CATIA, so I can't tell you if it's similar to that.

You can do that? Damn. I need to git gud.

I ((downloaded)) SolidWorks as I was interested in the assembly features. I was not satisfied with Sketchup so I decided to get it. It's certainly a much more complicated program than the former, though I would like to get better at using it.

>>32702239
Isn't there a guided tutorial like Inventor?

>>32702361
It does have a bunch of tutorials. I just need to get around to them. I haven't been doing much in the CAD field at the moment, though I might as well start now.

>>32702487
Shouldn't take very long and you'll probably learn a lot of ways to make your modelling easier and less time consuming..

>>32702487
If I were you, I would go through each of the buttons on the "features" tab and become familiar with their function. Maybe YouTube the ones that aren't so clear. Become familiar with constraints in assembly mode as well. If you do this, you'll be in a much better position to model and assemble most simple machine parts.

>>32703473
What's the best way to get large internal threads like that in Inventor?

>>32701599
can you share model please

>>32703823
Probably sketching the profile of the thread then using the coil command while subtracting material.

>>32704125
Still a got few tiny things to clean up like the springs. What format do I even export in?

Thanks for the tutorials. Lynda dot com is pretty helpful. My IT teacher got us to follow their videos to do web design and coding crap.

Also, the textures failed to port to the .3ds format for some reason. I'll include the .max files in all the previous version formats if you want to fix the textures up or something. I just reassembled all the geometry, I don't want to mess around with textures.

mah nigga. I take off features and simplify neutral format geometry all day. Everything else is so fucking shitty and handles assemblies so terribly.

The solver is NASTRAN, the stuff they use to analyze rockets and airplanes. It can also plug into other solvers, but would not recommend.

>>32708548
There's free CAD software, but uh, there shouldn't be.

>>32708586
i see. so only pirated shit, there is no freeware CAD stuff like adobe reader for simple CAD modeling?

also i want to buy a 3D printer but not sure what brand, everyone shits on makerbot because they went proprietary on their model files and stopped letting people openly share on their website

>>32708598
SketchUp and FreeCAD but I have only used SketchUp. It is dogshit for anything beyond actually 3D sketching.

>>32708548
if you're a student, you may be able to get AutoDesk products for free

I got Revit, Inventor, and AutoCAD through my university

>>32708598
No, I didn't mean piracy. I meant the FOSS CAD projects are fucking dogshit. I think Fusion360 is free for a basic license, but it can't do very much.

>>32708731
This.
Getting an student license for Inventor is fucking easy, they don't even bother to check your data.

CNC/manual machinist here, I've taken a bit of MasterCAM, and I've made a few parts using the CAD functions, but they're often a little finicky.

Is it worth getting and learning a dedicated CAD program? Are there any that are similar/play nice with MasterCAM?

I have pics/webms of a gun part I designed, toolpathed, and made but it's at home. I hope the thread lives until I get back (long shift).

is CAD used for CNC shit guys? or do CNC machines use some other type of software? i would prefer to only have to learn one type of software from the beginning, i want to start making things that a local CNC shop can make for me but dont want to have to make the files twice

>>32711512
CAD = computer aided design = drawing a part/making a model in 3D on the computer. Most parts made today are made on the computer using a plethora of CAD software.
CAM = computer aided manufacturing = is required to make CNC code that makes CNC machines do what for the go look more like part when.

thread has a couple options for CAD software, read above

>>32711512
Yes. Yes.

Most machine shops wont run your g and m code because some parameters are machine/controller specific. They will take your model however and translate it to cnc speak for you.

For 1 off parts expect to pay a mint.

Here's what it looks like in MasterCAM, btw.

Yes, I know the threadform isn't exact. I didn't really do root and crest dimensions.

The good thing is that exact modeling of threads isn't really needed, even when threadmilling. Taps don't care, obviously, you just need the right size hole, right feed per revolution (right codes for tapping, especially with rigid tapping), and so on. Modeling the thread is kinda bling, it'll usually be annotated in most manufacturing drawings and not actually drawn/modeled in as it can actually make some drawings and stuff less clear (too many lines everywhere).

Now, MasterCAM isn't a modeling software, that's why it took like five minutes to do this simple thing. I've heard that Solidworks and dedicated CAD software have actual functions for thread stuff, but I sadly have little experience in there.

>>32712021
This. Expect very annoyed machine shop personnel if your CAD drawing isn't dimensioned properly (what tolerances, surface finish requirements, dimensions of features, etc).
