Hey guys, How do I enter survey data made without a clinometer. I just thought entering data like dive data would work but apparently diving only takes place under water in Therion.... It doesn't matter whether I enter fromdepth todepth data negative or positive, it doesn't matter if I add calibrate depth 0 -1 before the data.... the following line just goes down where it should be going up: So this: data diving from to tape compass fromdepth todepth left right up down r112 h1 7.00 10.00 0.00 5.00 2.00 0.00 8.00 0.00 Produces the same results as this: data diving from to tape compass fromdepth todepth left right up down calibrate depth 0 -1 r112 h1 7.00 10.00 0.00 5.00 2.00 0.00 8.00 0.00 And the same results as this: data diving from to tape compass fromdepth todepth left right up down r112 h1 7.00 10.00 0.00 -5.00 2.00 0.00 8.00 0.00 Where it should be something somewhat comparable to this: data normal from to length compass clino 0 1 5.53 5.5 24.5 I looked at various manuals and examples, but they all assume you have a disto or some other clinometer. What extremely simple point am I too moronic to understand here? Thanks! Anton
