when i use annotate line to draw straight lines it doesnt draw it on surface even if i have surface placement on (pressing ctrl is a shortcut for eraser so that also doesnt work :S) how can i solve this
Hi Mustafa ccarlyc ,
I can understand your confusion.
The Annotate Straight Line consists of two endpoints, that are connected by a straight line, so that cannot follow a Surface.
The CTRL trick however does work, but you must first Left click; so: LMB (hold), CTRL (hold), draw the line (straight and on the surface).
This might take some practice.
