Hi!
I'm trying to make some drawings with librecad (Version: master SCM Revision: 2.0.0alpha3-32-ga4006c5).
When I create a line on a help layer it is shown as infinite one. Still if I turn off the "help" option (click on "printer" icon in the layer toolbar) it has some finite length (say 5mm). Ok, I'm turning on the help option back and trying to snap to the line (say to make a parallel one in distance of 50mm). If I'm doing this out of some surrounding (50mm) of actual finite line position, the snap does not work. If I make the actual line length longer, the size of proper-behaviour-surrounding also increases.
Same thing happens when I try to snap to an intersection of two lines which does not exist according to actual lines positions.
I can solve the problem making the help lines say of 1000mm actual size but this is a kind of not a proper way, isn't it? Also I've found that "help" option in layer properties dialog does not work good - it is always unchecked when the dialog starts.
Is it a bug or I'm doing something wrong?
