Q: Why cannot I calculate the error after picking control points for a new map registration operation? How can I activate the command for calculating the error?

A: If the command for calculating the error is gray, the reason is related to the selected registration algorithm and the number of control points:

1. If you select the Offset registration algorithm, then you can only pick one pair of control points, and there is no need to calculate the error.

2. If you select the Rectangular registration algorithm, then you can only pick two pairs of control points.

3. If you select the Linear registration algorithm, then you need to pick 4-6 pairs of control points.

4. If you select the Polynomial registration algorithm, then at least 7 pairs of control points need to be picked.

Note: The CAD datasets currently only support the rectangular registration method and the offset registration method.
