Hello Götz,
from the last bullet of Milan’s summary
- one can invoke new suggestions indirectly (by moving the control point in 3d by moving one of its validated measurements)
it follows that in the situation, when you adjust the measurement in 2D in a way that you change the 3D position of a specific control point, new suggestions can appear if RC can find new ones (different from the previous suggestions). However, the images that were banned by ‘clear suggested points’ should not appear again.
