Negative value result in positive offset

I try to follow the tutorial here:
https://www.sofistik.de/documentation/2020/en/tutorials/bridge-design/slab-bridge/slab-bridge.html

In the tutorial movie, the negative value result in negative (Y) offset as shown below:

But in my model, the negative value result in positive (Y) offset as shown below:

Hello,
In your screenshot I can only see your AutoCAD properties dialog with the offset. Can you also show us the offset dialog of SOFiPLUS? Maybe there are problems with the communication between autocad and sofiplus.
the easiest way would be if you provide us with your existing dwg file, you can upload it directly in your reply post. Thank you very much.

kindest regards

Hello,
Your global coordination system is upside down, you can see it in the upper right corner, so you look at the axes from below. Please turn the cube in the upper right corner in the right direction.
Then open the systeminformation dialog and change the orientation of the deadload to "Positive Z-Axis.
Now your system should look in the tutorial
