I figured out how to inverse along a curve (1..2..3). It seems to go right. The problem is how to inverse along the curve LEFT.
I'm evaluating and I think MicroSurvey will meet our need for a reasonably priced cogo/drafting package for motel room use. Ian persuaded me to stick with the program and, to be fair, my 30 minutes of experience so far is not enough to make a good judgement. It does appear to be workable, unlike a competitor's similar cost program that I tried a year ago, one word-horrible, awful, useless, etc.
