In M8 there is a handy utility that appears when you press the INS key while creating vector features. The functionality is documented under the heading Lines and Areas (http://www.georeference.org/doc/dialog_mode_and_visual_tools.htm).
I use this tool to quickly create line of a precise length and bearing, usually using existing features as a guide (creating new parcels of land exactly adjacent to and at the same bearing as existing parcels).
I believe there has been significant effort put into CoGo functionality in 9 (http://www.georeference.org/forum/t149948#150098), and I have reviewed both the "Snap Modes" and "Traverses" topics in the M9 documentation, but I can't figure out how to replicate my M8 workflow. It is likely that I don't understand the survey traverse functionality.
How would I create a new line of a specified length at a precise specified decimal degree bearing (-6.994 deg, for example)?
