Hi Peticel, the default dimension preset is stored in moi.ini and that one will reload just when you start up MOI. The other dimension presets are saved when you save to a .3dm file and will be loaded when you open that .3dm file. They won't be loaded just on program startup except if you set up a template file under Options > General > "Template file".

When you set a template file that will load stuff stored in .3dm files like the dimension presets and styles list on program startup or File > New.
