thank you very much for your feedback.
I tried to reproduce the issues you have mentioned regarding geometries. I created models called Base, Yoke, Head, Beam. After that I added geometries, named them and linked the models I had created. It worked fine for me. I was also able to define a name while creating the geometries and to rename the geometries and models afterwards.
Could you please describe more precisely what you did when it did not behave as expected.
Resolution: The DMX values in the GDTF file are exported to the file with the resolution that is set for the DMX channel. For example all DMX values of a DMX channel with a resolution of 16 bit are exported as x/2 to the file.
Changing the resolution of the individual input fields only simplifies the input of values.
At the moment the resolution of the input fields does not change if you switch between DMX channels, but the resolution of the input fields is reset to 8 bit if you change tabs. I guess the resolution should also be kept if I switch the tabs.
