Here is what we are using for my class:
https://drive.google.com/drive/folders/1wPRqBAiiNjEvtVtTtrxE4BLH2l18hIiYOne is called Draftsight 64 and the other is called DraftSight_HotFix_2017R3
Install the draftsight64 first and then install the DraftSight_HotFix_2017R3 (the hot fix is just a patch that windows requires to run this version).
You will need to run this on a windows 64 pc.
It’s free and pretty good.
