There is also AutoCAD LT for $45/month on Mac or PC. The expensive version of AutoCAD has 3D features and rendering that is not commonly used in shop drawing or as-built generation. While it's still not full featured, nearly all of those features will not get used.
Budget Drawing Markup Tool: AutoCAD 360

When it comes to drawing software, even simple tasks like markups and redlines require software that can cost thousands. Many security professionals have a hard time finding a CAD solution they can afford, much less that does the job they need.
The same company that produces AutoCAD is now offering a web version that costs $5 per month.
I found out by accident that you can view 3D models in LT, just lack any controls to edit them.
This leads me to believe the 'core' is basically the same between LT and full versions, they just turn a bunch of stuff off for the cheaper version.
