I am currently using the 2010 trial version. I am drawing multiple short lines and I need to draw another longer line (polyline) that goes through all of those initial short lines, but in a way that the longer line passes through the MIDPOINT of each of the shorter lines. I have been typing in "midpoint" each time I want to select another point for the polyline. Is there a faster way to do this? Some option that I can select and it will automatically go to the midpoint each time I click on a line, instead of having to type in the command "midpoint" each time?
