I came to this board looking for solidworks threads, do those exist around these parts?
Looks like mostly blender and gay right brain shit

I lurk here. I do solidworks. Cad threads happen, but are rare. Sometimes they also happen in /diy/.

Ask away

>>707518
Same here. Just blender thread after blender thread...
I've worked in sheet metal custom design using Solidworks and Creo for almost 10 years, ama

can you post your best work? Something to impress us?

Poly modeling hobbist here. Wanted to check some CAD for making high-poly and exporting it to obj\fbx for retopo\baking. What you can recommed for cad part? I kinda know few things about AutoCAD and Solidworks, but nothing worthwhile and only real experience with cad was MoI3D and i like it's simplicity and small size but it feels kinda half-baked for now. Also how Fusion 360 works with it being "cloud based" ?

>>707571
If you can get Solidworks, get it. Otherwise Fusion 360 is free for hobby use. You have to agree to licence terms. And they are in process of changing terms of licences or sth. So you have to read through if you apply. Otherwise it works. Files saves to the cloud, bat you can also archive it an your pc.
You can also try free FreeCad or Openscad, if you like typing.

>>707574
Oh, so fusion's "cloud" stuff is only about managing your fiels etc? They put emphasis on cloud sometimes that i got feeling that it has something to do with some kind of calculations or simulations. Also i can get myself solidworks, but wanted to know if fusion is valid choice, because i only heard good mention of it from here https://80.lv/articles/building-guns-for-doom/

Yes, I design and build two and four stroke combustion engines. I'm currently working at a small company in Austria specialized in engines for light aircraft.

I have some experience in 3d modeling, along with some CAM programs(subtractive manufacturing), But when I try CAD(additive manufacturing) I'm completely fucking lost, lads. Booted up fusion 360 last night, managed to make a basic hollow box with no top. But the workflow from 3d modeling, to CAM, and then to CAD is so entirely different. Couldn't figure out how to make a god damn square hole in the bottom of the box.

Any fusion 360 nerds here? In a 3d modeling program i'd use a simple boolean operation, in a CAM program like featureCAM I'd put layout lines ontop in the center of the part, and offset additional lines from there to form my hole. What would it be called for something like this in CAD?

I tried using the hollow tool on the inside face of the box, but it just throws an error and won't let me do it.

>>707576
Mostly for files, but also simulation, generative design,... Basic CAD happens on your PC.
>>707577
Post pics? I might have some questions.
>>707578
Watch some tutorials. Always start with a sketch on a plane (let say x-y plane). Draw square, dimension/constrain it. Extrude. than click on face- make new sketch. Draw square, dimension/constrain it. Extrude- but here you extrude into the part. extrude will become extrude-cut. Preview goes red. You have a hole
You could also do it all in one sketch, but is a little more advanced, maybe?

Did a ton of 2D stuff for a CNC plasma cutter on AutoCAD. Nowadays I'm designing industrial stuff on Solidworks, mainly metal sheet stuff that I have laser cut and bent to make canopies, structures and shizzle. Normies are always amazed when they walk by my station and I'm just orbiting models around.

It's 8:30 PM here, so I'm not at work. Naturally I can't show you assemblies of our products, but I will do my best to answer questions. I have a solid background in many CAD packages, including high end solutions from Dassault and Siemens.

>>707588
I meant finished product, What you sell. if that is not a secret.
For beginning just, do you make aftermarket parts or are you subcontractor for big brand names?

>>707571
SolidWorks is REALLY expensive, but I don't think anything can beat its ease of use. AutoCAD is outdated trash.

I'm making a speaker out of 3/16 metal plate and I wanted to integrate the grill for protecting the drivers into the baffle where they mount.
This sewer grate thing has the pattern I want except for that one bar cutting through, I just want diagonal slots at a 45 degree angle across my speaker baffle
What would be the easiest way to achieve that pattern so that it all gets cut out at once when I throw this on the cnc plasma

I've drawn in with red in ms paint what i'm after
I'm new to SW so yeah i'm kinda retarded

>>707617
I'm pretty new to cad, but if this were a CAM software I would create a single 45 degree line in the center of the circle and offset from that. Pretty rusty with the math involving segments of circles, but since this isn't dimension critical you could eyeball it to be pretty close.

also 3/16 is pretty fucking thick for a speaker grill. What monster speakers are these things going on?

>>707583
if pic related is what you mean by starting with a sketch on a plane, then fusion 360 just got a whole lot easier for me.

>>707648
Now I've run into something else.

Can anyone explain why I can't offset a new line on an already created offset line? I can't think of any reason whatsoever why autodesk would prevent users from doing this.

>>707617
I'd put two centerlines/construction lines at 45° in your circle and draw the largest slot in the middle on one. Use the other one for pattern direction. Then, use sketch pattern to build the slot pattern out and you can adjust your instance count and spacing from there. I am pretty sure you can break the "equal" constraint on the slot lengths and adjust them to fit. Then just mirror the sketched slots across the centerline for the other side and extrude cut.
I usually use feature patterns and I'm sure this could be done with some sketch or equation driven pattern easily. I haven't done anything quite like this with the varying sizes and don't have solid works in front of me at the moment, though.

>>707656
I think i'm gonna play with the spacing some more but I figured it out

>>707656
I played with it and got it looking decent, epic ty bros

Anyone else made the transition from Fusion 360 to Inventor? i've had to recently make the transition and i'd go back any fucking day if i could, Inventor fucking sucks.

>>707649
no idea why it does that, just offset the original line
but honestly, it wouldn't be at all difficult for them to make offsetting an already offset line work
