Points importation

Hello Omran,

I tried to put them into the "new points" group without coordinates (0 0 0 instead) thinking that it won't influence calculation

Least squares adjustment works only in linear models. Since planar or spatial networks are nonlinear problems, one has to linearize the functional model using a first-order Taylor series. For that reason, appropriate approximation values must be specified by the user. In most cases, [0/0/0] is not a useful choice.

kind regards
Micha
