I understand the concept, but I am still not sure how/or if I can calculate actual heights of the points (e.g. side points).

When we go to the field, more often than not - we dont have heights of the benchmarks so we use custom height of 100,00 meters to check loop closure, and in the office we calculate data with actual heights.

I tried transferring points between different groups but what ever I did, I coudnt get actual heights.
