Endangering the entire forum just so you can get something for free isn't "helping others" and I'm surprised you are not already banned. You certainly will be soon.

On the original topic of the thread: I like, and use, Qcad for 2D stuff like the mechanical drawings in my module manuals, and FreeCAD for 3D, such as defining models for Kicad's 3D viewer; both are free software.

I have no real professional experience with cad, but in class we use Ironcad, witch from what I've heard is a bit like a crossbreed between a "real" program like Autocad, and Sketchup. Basically you drag and drop shapes to model a 3d representation of what you want to make with all the cad functions included, plus a tool to pretty quickly handle each shape or feature of the stuff your working with, and then, pretty easily render a 2d (top-front-left etc) blueprint ala architect drawing, witch is probably why you don't want if you want to make circuits, although i believe its possible to get it done, but excellent if you want to make a decent and representable writing for building a case for instance. Plus it got a lot of pros too, like presets for constructing sheetmetal products, adding a BOM to your drawing and a pretty decent learning curve.

As i said, never had very much experience with cadstuff except for manual blueprint drawing, but its pretty dope once you get the hand of the basics of it, which took me perhaps 5-6 hours. I took me like...3 h just to learn to make a baseline with the quick commands in Autocad so...it does the trick so far.
Runs on Pc, and on mac if download some platform shit.

Sorry to blast you with this much text, but i really like the cad part of projects, and I'm new here so there it goes. And i study furniture carpeting; hence, the cadblitz.

For 2D CAD I use DraftSight, the free version. It's capable enough that even tho I have a full AutoCAD license at work, I'll often find myself using DraftSight instead, for simplicity and cos it starts up about 20 times faster.

For 3D stuff I really like SolidWorks, which I use at work, but (as someone else in this thread pointed out) it costs way too much money to justify using it at home. I haven't really found a good free/affordable alternative yet.

And for PCB CAD, I (for better or worse) never used Eagle and thus don't have the mental technical debt that seems to keep Eagle users using Eagle. At home I use KiCAD, and I have been using it long enough now that all of its eccentricities don't bother me. At work, despite my Altium Designer cheerleading, I (have to) use PADS...

Been using SolidWorks professionally for about 17 years.

Started using Siemens NX about 7 years ago.

For easy stuff SW all the way, for more complex stuff, NX is VERY powerful.

If you're a "circuit" guy, like me, it's worth getting a design engineer to check your work first for manufacturability first.
Hey Slow_riot, have you experiences with kicad too, my Idea is to do the mechanical work with freecad and the electronic work with kicad. Is freecad hard to learn?

Thanks alfrede

Yeah, and 7 grand a seat..
Yeah, it has come up a bit in price, but is still cheaper than many of the other professional options with similar features.

Hi Alfrede

I have looked into KiCAD, although that package is for schematic capture and PCB layout, whereas FreeCAD is for mechanical specification. KiCAD is an excellent piece of software for general purposes design including analogue and digital.

I think all mechanical CAD programmes are hard to learn, because their range of uses is so vast. It can also be complex because there are many different ways to solve each particular problem.

There are many Youtube videos that can give you some ideas. It's a great software package.

Hey Slow,

thanks for your answer. I know knowdlege is the one thing but software and the ability to tranfer the knowledge in software the other. I think when i am fit enough in kicad i will show what freecad can do.

In scholl we learned Eagle, but the new Licence Model broght me to Kicad. I think Open Source Software will be a big + for all DIYler.

Cu.

@Jordanb is referring to Rhinoceros 3D

https://www.rhino3d.com/6

We use it at work, where the licensing model via a Zoo server works really well for us, and it's a great 3D modelling tool.

The Price tag may put most DIY-ers off, though.

For home use I find the KiCad / freeCAD works well for me, though I'm mainly just using freeCAD for creating / converting Component Models for import into KiCad's 3D Renderer.
