Crosshair angle

I am new to this program from using AutoCad for several years.

My problem: How to change the Crosshair angle. The angle is at about 5 deg. when bringing in a .dwg created in Autocad. Correct in new drawings created in DraftSight.

Is there a way to show the line length when drawing a 2D line and the radius length when drawing a center circle?  This is a feature in AutoCad I have become used to and saves a ton of time as apposed to giving a line a length to go to.

Is there a version of DraftSight that supports a tablet and custom tablet menu?
