Hi Martin Line 41 in MillCreekCave.th names the first elevation scrap in the first of the two elevation maps.
================== map MainPlan -title "Mill Creek Cave (PUL-012) - Plan View" # Main survey scraps Entrance1 EntranceConnector Entrance2 TJunction1 TJunction2 TJunction3 endmap map MainPassageProfile -projection elevation Elevation1 <<== Line 41 Elevation2 Elevation3 Elevation4 Elevation5 Elevation6 endmap map CPassageProfile -projection elevation ElevationB1-C2 ElevationC2-C5 ElevationC5-C6 ElevationC6-C7 ElevationC7-C8 ElevationC8-C9 ElevationC9-C11 endmap ================= The scrap is defined like this in the th2 file: scrap Elevation1 -projection [elevation 330 deg] -scale [0 0 1600 0 0.0 0.0 40.64 0.0 ft] And the select/export section from the thconfig file is this: =============== # Entrance passage elevations select MainPassageProfile at MillCreekCave export map -proj [elevation 330 deg ] -layout profilemap -o MillCreekCaveElevation1.pdf # C Passage elevations select CPassageProfile at MillCreekCave export map -proj [elevation 270 deg ] -layout profilemap -o MillCreekCaveElevation2.pdf # Main map select MainPlan at MillCreekCave export map -proj plan -layout mainmap -o MillCreekCave.pdf ================= I have a thought on this ... The main passage of this cave starts out going northeast, then gradually bends to the east. I chose an angle of 330 degrees because that would give me approximately an orthogonal view, as if I were standing off to the right of the passage to look at it. The second passage goes almost straight north, so a view angle of 270 degrees gives the same orthogonal view. If the passage were a train heading northeast and I were standing on the right-hand side of the tracks, my best view of the train would be on an angle of about 330 degrees. Is that the wrong way to choose those angles?
