Translations:TechDraw 2LineCenterLine/24/en

The centerline between 2 lines is drawn between the midpoints (m0 and m1) of the lines that connects the endpoints of the selected lines (p0 and p1), see the sketch. Depending on the point order there are 2 possibilities to draw the connecting lines. The attribute Flip Ends flips the way the connecting lines are drawn. In FreeCAD 0.20 the point order is automatically determined so that the Flip Ends attribute is no longer necessary.
