I have modeled my corridor & cul de sac and everything seems to be working great.
Except that, when I go to plot, a bunch of lines are showing up that are on a no plot layer and are not even visible in the viewport.
I have attached the two screen shots of the viewport both before and after plotting.
Any help would be appreciated. I am fairly new to C3D and there is a very good chance it is user error!
Rather than use layers, turn off the display of lines in your link styles (see Code Set Styles.)
I have the same problem. I know I can turn them off in the style to avoid plotting them, and I'll do that if I have to. But I like having them visible so I can quickly grab one and look at the cross section.
Never had this problem in C3D 2012. (I'm now working with 2014).
