I have 2 lines, want to find and mark theire intersection point, there is any command that I can pick to lines and a point (or any othere suggestion) will be created?
not sure I got you 2. I can find the Intersection point by going to OSNAP, mark X in Apparent Intersection squre. but the APP typing result to nothing
Unknown command "APP". Press F1 for help.
what am I doing wrong?
"while in a command type APP to use it."
So start a command line POINT or LINE, type APP, pick your two line, and voila, you are at the intersection (if they intersect).
APP is not a standalone command (why did you type it as such), and cannot be used as a running Osnap (do not check the box).
