What's in it is a 3d Axis (for 3d environments), a fake 3d Axis, (for fake 3d, and to let me know what direction is what), and 3 "perspective rulers

Oh yeah I almost forgot. If u download the whole folder, there are also sketch styles in there too. there are 6 colors with their own dull fills to tell them apart. Since the introduction of the FBF layer, the drawing update, and since I have drawing tablets, I figured I'd make some styles for it as well. Hope u get some use out of it as I am.

Edit: Well since dropbox won't put everything in a folder like how I tried to present it, I recommend u exporting it into a new folder, THEN saving to ur library. (dropbox newbie I am)
Edit: Link update to a zip folder instead. Thanks Greenlaw!
