Hi. I am using CADEMIA and I have written some posts about it here:
I would sugest for CADEMIA that it can draw lines from intersections in an easy way.
You can draw a line from another line in 3 points: begining, midle and the end of the line (snap options). But if I want to draw a line from intersection of lines, I should press a lot of commands to select the lines to be able to draw it from intersection. I think that this could be easer.
I think that CADEMIA is agreat work.
