Is there an easy way to wind the maximum perpendicular point between two lines?
I'm trying to find the maximum perpendicular distance between two lines and the measure tools don't seem to have a function for this. I'm currently copying parallel to find the point but it's a bit slow and imprecise, is there a better way of doing this?
The attached image should show what I'm trying to do.
Offset the yellow line a significant distance beyond the red, and construct a minimum distance line between the 2
in your example its an arc and a line there is a mathematical solution with equation ( google chord height) to find out the height of a cord so you could use the calc to check your answer but I would use place circle by edge and use tangent and perp snaps and Mstm will find the solution as the diam of the circle.. all the equations are here

That won't work either for the simple reason, how do you know that your chosen start point of the circle is precisely at one of the 2 possible furthest points? You're eye-balling it and that is not an accurate solution to the problem.
The idea of circle theory may not even be applicable; the op stated in the title and original post that its the maximum distance between 2 lines (not Circle/Arc). That what appears to be Circle/Arc in the image, may/may not be relevant. Regardless, the option proposed by both myself and MaryB is the only one which I can think of right now which will give the OP a way to accurately attain the maximum distance between 2 lines/arcs etc...
That's something I had never come across! I looked up sagitta and wrote a VBA macro to create one...
