As a test, I've been trying to re-build a network manually from a csv file and turn it into an AD VA fieldbook file. I'm having a big issue that I'm sure is programmed into the software, but I don't know how to fix it.
Here's my process for creating a SS new observation, let's call it point 101. Point 101 will be shot from point 2, which has a backsight of point 1. The backsight orientation is set to 0.000, so all angles are measure clockwise (right) from the backsight angle.
Station Setup:
1. Create a new setup in the Network in Survey Toolspace for point 2
2. Set the backsight as point 1
3. Set the Backsight Orientation, Face 1, and Face 2 to 0.000 (all the sideshots will be AD VA, so the face angles don't matter... right?)
4. Set the instrument height to some arbitrary number
Observation Entry:
1. Go to Edit Observations for point 2
2. Create a new observation called point 101
3. Measure the turned angle (using the c3d inquiry tool) between the backsight line 1-->2 and the sideshot line 2-->101
4. Input the turned angle that was measured into the Angle column in the Panorama next to point 101.
>>>>The angle changes when you press enter! It increments by a few hundredths of a degree?! Why does this happen? The Angle Type is set to "Angle".
5. Measure the slope distance using a c3d line label with a special expression to calculate slope distance
6. Input the slope distance into the Distance column in the Panorama
>>>>>This value does NOT change.
7. Measure the vertical angle, again with a special c3d expression in the line label
8. Input this angle into the Vertical column
>>>>Again, it changes, incrementing this time by up to 2/10ths of a degree! What is causing this? The Vertical Type is set to "Vertical Angle".
I am using the default Sample Equipment Database, although I don't know what would cause this in the equipment database if anything.
So... why are these angles spontaneously changing when I input them? My lines are close to perpendicular, so I measured to see if somehow it was getting a bearing from north, but this also isn't the case. I'm stumped.
It's not a small error either... in just 3 stations over 500 feet, I am already 3.2' off!
