Verify

This tool allows the user to define a 3D point in an iterative way. The iteration continues until the user accepts the resulting point. At each iteration step, the point so far is verified and confirmed by the user. The verification works like this:

1. The user defines a 3D point.

2. The system verifies the point and asks the user if the point is accepted. If so, the user answers YES and the definition is completed, otherwise the system will continue with step (3).

3. The system makes the point the current one and lets the user define another 3D point. Operation Complete, at this stage, means accept.

4. The system verifies the next point and asks the user to key in relevant coordinates (XYZ), that means, the satisfying coordinates of this point. Different answers result in different actions exemplified below:

   <CR>	Keep all coordinates of the previous point. Go to step (3)
   <XYZ>	Keep all coordinates of this point. Go to step (3)
   <YZ>	Keep Y- and Z-coordinates of this point, keep X-coordinate of previous point. Go to step (3)
   <X>	Keep X-coordinate of this point, keep Y- Z-coordinate of the previous point. Go to step (3)

Operation complete means that previous point is accepted.
