I would like to know how I can make a curve with for example 90 degrees on another curve.
If I use the funktion <90 that would work , but let’s say now the curve is allready on an angle, 10 degrees. I could than use <80.
But is there a way to have the curve at an angle relative to another curve?
do you mean curve in matter of Line or really a curve? for Line you would have after calling up the command Line, several options including angled. there is also a button in the Line tool palette for it. it will let you redraw the base curve from which you can draw your new line in your needed angle.
