Note: 1. When using the "Center + start PT" and "Start + End + Point on Arc"
methods to calculate the radius of the reference arc, only the 2D projection
coordinates are considered, i.e. the radius is calculated in the 2D plane, independent
of the Z coordinate of the reference point.
2. The graphical interface draws a 2D planar graph of the reference arc, but the
elevation information of the reference point is still retained and effective when the
stakeout operation is performed.
3. When using the "Start + End + Top" method to set the reference arc, the top point
of the arc is always between the start and endpoints.
8.8.2 Reference Arc Stakeout
Enter the setting interface of stakeout parameters, you can select different stakeout targets and set their
corresponding stakeout parameters.
Stakeout point
Select the stakeout point item, set the arc distance, diameter distance, and other parameters, and then click OK to
jump to the reference arc stakeout interface, click Save/Measure- Store to calculate the stakeout information, and
expand the graphic interface on the right to display the current position, prism points and the position
relationship between the stakeout points.
Arc distance "line": set to a, then the arc distance a is offset clockwise starting from the starting point in the
reference arc, and 0 < a < total arc length.
Diameter distance "offset": set to b. If b<0, the distance b will be approached the center of the circle starting
from the starting point; if b>0, the distance b will be moved away from the center of the circle starting from the
starting point.
