@yorik @FreeCAD how compatible is it with autoCAD as most businesses still want autoCAD compatibility to get work

It mostly depends on what you call "autocad compatibility"... All of the above is 100% compatible with DXF format (and DWG too but needs an addon), which for me is more than enough. Or do you mean something else?

@Coneng @yorik @FreeCAD
Most businesses in architecture and construction, you surely mean. In manufacturing we have long stopped using that POS. Extremely happy to not have had to touch AutoCAD since 2007. It wasn't a day sooner. We still need to provide DXF files to suppliers, but most CAD programs can export to this format.


#AutoCAD achieved feature completeness by version 10 (IIRC, maybe 11?), which was also the last #UNIX version.

Everything after that was just trying to get people to pay for updates.

As far as I know, AutoCAD was never available on UNIX. From the start it was developed for microcomputers, specifically the PC running DOS. It switched to Windows around V12 or V13. Prior to that, it had been briefly available on MacOS in the early nineties (V9 to 12 I think), almost a decade before Mac was based on UNIX.

A friend gave me a copy of v2.17 on a 5.25" floppy. My university's IBM-PCs had v2.62. That was in 1987-88.

And to say it achieved feature completeness around 10 or 11 is doubtful. It didn't even have proper 3D solid modeling.

Oh yes it was! I should know since I was a user.

#AutoCAD was a drafting solution not parametric modelling software. It was following the success of #CATIA and later #SolidWorks (once PCs started to become powerful enough) that they started competing in that market.

I disagree, AutoCAD was never parametric and still isn’t, apart from the sketcher. It is more of a CSG workflow, which does have its use.

Around 1998 they released Mechanical Desktop (MDT), which was parametric - but it was actually a layer over good old AutoCAD, it retained all its 2D/3D commands. The company I worked for at the time sent me on training along with 2 colleagues to learn v1.0. We never used it much, it was dog slow and a pain to use. But after using MDT, learning other parametric CAD programs was pretty easy (though I’ve never tackled CATIA nor Unigraphics/NX).

MDT was left in limbo around v3 when they started developing Inventor, at some point they discontinued it.

I know. I'm not exactly a stranger to AutoCAD. That's why I said “competing in that market”.

Interesting. There's no mention of AutoCAD ever running on UNIX anywhere that I could find on the Internet (I did search before replying).

@Coneng @FreeCAD @0
I heard about the unix version too but never knew if it was a rumor or not.. kind of agree too that autocad never really evolved anymore, say after v13 or 14 (ellipses, splines and acis modeling). I bet nobody at adsk dares to touch the autocad code anymore :) imagine the mess it must be with decades of paint layers on top of the old stuff


> I bet nobody at adsk dares to touch the autocad code anymore

That would be my guess too. 🙂

Btw, for more than you ever will want to know about #AutoCAD, #AutoDesk, the state of software development and the startup market in the #1980s, head over to John Walter's #autofile:

@normand @Coneng @FreeCAD

@yorik @normand @Coneng @FreeCAD

> The Autodesk File chronicles the history of Autodesk, Inc. and its principal product, AutoCAD, through contemporary documents edited and annotated by Autodesk founder and former CEO John Walker. The book traces the company from the first glimmer of an idea in the minds of the founders, through start-up, initial public stock offering, and growth from a loose confederation of moonlighting individuals to a leader in the industry of computer aided design.

@yorik @normand @Coneng @FreeCAD

> John Walter

Sorry, that's my phone's way of spelling John Walker.

For a bit he was also (in) famous amongst the general public in the early 90s because of his candid stance on the collapse of communism.
