All,
In 9.3, if I was trying to split a polygon (or drawing a line, for that matter) on a particular bearing, all I had to do was establish 2 points outside of the polygon, make sure the "perpendicular to sketch" box was checked on the snapping toolbar, and the cursor would snap to, or adopt, the bearing that had been established by the previous two verticies. It would basically guarantee that I maintained that course exactly.
This feels like a very basic question but my searches have come up empty on this subject. Is there any way to do this in 10.0 (ArcInfo license)?
Thanks
