What do you like best?
I use DraftSight to read, make edits, modify, and scale 2D scene drawings in .DWG format. The functions are simple to use, the program loads fast, and it's free to download. Great alternative to AutoCad as long as the task is in 2D and not too complex. I can add lines and objects in layers and export to PDF easily.
What do you dislike?
DraftSight is only suitable for drafting in 2D. It doesn't handle 3D models or manipulate them. For that, I would use Solidworks or 3D Studio Max. The scope of DraftSight is limited to making simple editing (lines, text) of a 2 dimensional model.

What business problems are you solving with the product? What benefits have you realized?
I read, make edits, and revise drawings in .DWG format using DraftSight. I also use it to create scaled scene drawings from Google Earth aerials. It's like a free version of AutoCad with familiar graphical interface.
