Thanks
I found a script that worked.
[quote="Chris Fullmer"]Perpendicular Face Tools
Description: Three Perpendicular Face tools to help create faces perpendicular to the end of lines.
Usage: Activate it at Plugins>Chris Fullmer Tools>Perpendicular Line Tools. Change the size of squares by entering a new dimension into the measuerments box after the face has been created. Change the radius of circles by entering "12s" for 12 sides into the measurements box. To use the custom face tool, create your face flat on the groundplane. The script attempts to line up the x axis as the bottom edge of the face.
New Video for v1.1 (outdated for 1.2. Doesn't show that you can hit the up arrow key to rotate).
