I need to somehow remove xxx_diagram output file from my project.
I tried to merge the model and diagram files into one, but result is some
mixed XML. That is unacceptable for me. In my model file (not xxx_diagram)
I have everything what I really need (structure, nodes, positions on
diagram...etc.).
How can I prevent writing to xxx_diagram file and how to successfully load
my model in project (without xxx_diagram file).
