Hi Anthony,
Need to rename either the narrow .htm menu name to match the the javascript .js name, (with different extensions of course.),
or vice versa. (With matching shortcut key of course.)

Variations of scripts and menu's, with modified, but matching names, can have different shortcut keys.


I have a few ideas of how to automate the top and bottom arcs, maybe using part of trim....
The bisector line script looks interesting. There is a wealth of information in Michaels scripts, which I'm trying to underestand...
