Hello. new to all this. Using pdf manual 2.0. using librecad 2.1.2. Got to the section on drawing isometric views. per the manual set preference to iso. set line to two point. manual said yellow cross hairs should change from X,Y to X,Z. it does not. iso grid pattern is show, but still drawing X,Y 2D. But command line makes 3d. what did I not set right? Thanks.
