@dassauerkraut >like all of AutoCAD suites is windows based
That is false.

Sure there is some proprietary malware CAD software with developers so incompetent that it only runs on windows that somewhat operates - but making your business rely on that is of extreme risk (as the proprietary master or microsoft could command the software to stop working at any time and you couldn't do shit) and also costs a fortune in the long run.

There exists a number of CAD suite's for LiGNUx that work just fine.

I've noticed that FreeCAD works perfectly fine and is quite good for most design jobs (the interface seems counter-intuitive at first, but soon becomes quite pleasing as it's easy to set exact dimensions) with the only major issue being that performance with large designs is bad - but it is also rapidly improving and I do reckon it will eventually will become functionally superior to all proprietary CADs - just like all free software that has had substantial development work put into it.

People in factory jobs and the like quite enjoy FreeCAD as there's no bullshit proprietary license or a fortune in monthly rent to pay and you can just shove in .step file and get out a drawing with labelled dimensions the other wagies can understand.
