  1. Hi I am 73 yo and survived 5 strokes and 4 heart attacks. I have 2 Diplomas in Mechanical Engineering. Also I served an 8000 hour Tool and Die making apprenticeship. I owned a Machine Shop for 32 years. I am very poor financially. I get Social security ans Food stamps. At 73 I enrolled in a solid works drafting class they wave the tuition fee for senior citizens, but charge a student activity fee about $259. any way My car blew the motor about 2 months ago and I never finished the class. I tried to down load the free student edition of solid works, it is always malfunctioning. i have a Dell 16 gb memory 3.0 speed sorry don’t know the lingo. and 64 bit windows 10 I tried the open source program “Free Cad ” I like it but it always malfunctions. Any way I got design spark mechanical free down load 64 bit. it worked ok until Windows had an automatic up date. My point is none of my free software cad works. without a failure freezing the programs. My wife died from breast cancer 10 years ago age 60. I lost 19 million dollars so I cant hire some one to draw for me. what should I do to get a “FREE” cad program to work? Harry Lyga in Connecticut PS I would like to get Auto Cad Fusion 360 to work or The solidworks.. I just saved up enough to get a used car.

  2. I used to be industrial designer with SolidWorks on my table; retired, I am missing the creativity I had with SW. What comes close if I am now on (and like it), with LINUX?

    • Similar to Autocad: Draftsight (not supported anymore, but you can still use 2019 version, just returning the date of your system), Ares Commander, Bricscad (both paid) , and qcad that is free.

  3. Free Autocad Alternative is the open source software I have been looking for, and I appreciate the software and the essay explaining the ways and usages for the 15 types.

  4. Opencascade is a library used by FreeCAD and probably solvespace, it should not be listed as an alternative as its the “core” with an API, nothing normal users can use.
