Hello,

Of course: https://www.dropbox.com/s/uz2rf1efszl6kmm/190721OIYJ.gsi?dl=0

Okay, thank you. I took a look to your provided file. The problem is, that no station line is defined. The file contains observations but it is not clear where the observations come from. This is the first line:

110001+0PIL5999 21.322+11843030 22.322+10998153 31..00+00026382 51....+0000+034 87..10+00000000 71....+00000000 72....+00000000 73....+00000000 74....+00000000 

It defines the observation to the point PIL5999, but what was the station name? Since this information is not given, JAG3D ignores the observations.

In fact for the slope distances and zenith angles it was only one tree item but for the direction sets I have several tree items containing one stations each, here is a screenshot: https://www.dropbox.com/sh/exc1xubl3wl3b6c/AACL-ggM7KZtjJ-MCvLN1eEKa?dl=0

Okay, perfect. Due to the unknown orientation of each direction set, these observations must be separated. Zenit angles or slope distances can be organised by a single group - that is okay.

If the project is still not running, maybe, you can upload/provide the JAG3D database of you project (3 files: data, properties and script file).

Kind regards
Micha
