Inversing curves

Postby DaveK » Fri May 21, 2004 10:42 am

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.

curves

Postby Glen Cameron » Fri May 21, 2004 10:55 am

Curves calulated in COGO by doing the 3 point inverse are always done clockwise.

We do have other curve options of course, that may assist you.
1) CADCurves, if you simply pick on a curve already on the screen (no command running, just pick it), the dialog shows info on that particular curve and also gives more options at the bottom of the dialog to calculate more curves with several different methods.
2) In COGO we can also calculate a curve in 2 different ways. At the command line, type in COGO and on the option bar you will see 2 options, CURVE (calculates a curve based upon a starting point and arc, radius, etc.) and CB (calulates a curve based upon Chord Bearing).

I hope one of these options will assist you.

What did I tell you? 13 minutes and Glen was on your question like a chicken on a June bug!

Watch out for Medocino's #1 cash crop growers next week. Those guys don't pay any taxes and don't play by the rules. State forest land is prime growing area, too.
