- Because i'ts equal in 2D part. Very good, has free version, and multiplatform.
- the free version really read/write autocad files.
- Despite my continuous research, I have never found anything else closer and compatible to autocad. I say this with a critical spirit, because compatibility is good, not perfect ...Unfortunately.
