Hey! I'm developing this kind of CAD software, right now I'm working only in 2D (very simple), I can draw a lot of lines but when I zoom in the points of intersection move and lines don't seem to actually intersect nevertheless they do... I believe it has to do with the way OpenGL maps the 'world' vertex (which are double) to pixels (int). I'm wondering if there is a way to do a 'regen' like in Autocad ..... Any ideas? suggestions??

It is not clear what you mean.
Also, doubles are not directly supported by most GPUs.
You should write some code here or upload something if you want help.
