Hello,

I wanted to import the raw data in GSI format but it didn't work (nothing happened) so I created a text file where I copied the data.

Can you temporary provide the GSI (e.g. using Dropbox or such kind of service)?

I have a file for the zenithal angles, another for the horizontal angles and a last for the distances. So one file only per group of mesurement type in the tree menu.

Okay, but were the directions separated by sets during the import or was only one tree item added per observation type?

"...depending on your task/project, select the desired point types."

Ok so I tried to use the datum points but it could not invert the normal equation matrix.

Within a free-network adjustment, only datum points and unknown new points are valid/supported point types. That means, you can not use reference points and/or stochastic points together in a project with datum points.

regards
Micha
