i got a several problem with a Entity, relational and logical diagram that i made on oracle datamodeler, its work super slow, like 20 minutes waiting after change the size of a table, scroll down, or save the project.
I got a powerfull machine and i tested i anothers computers but still slow.
i got the 19,4 version.
Another program that can open dmd files? i cannot use draw.io or another program for create the diagram again from scratch, i have to send the dmd file, its for a project on my college.
