Hello
I want to learn how to get Bentley software (MicroStation, inroads, open roads, open-bridge, ECT.. ) set up on the machine. and how can I adjust the configurations according to the DOT seeds ,files, libraries, and so on .
Is there training to do that somewhere?
As Tim pointed out most DOT's provide some type of documentation on installing or setting up their Workspace/Configuration. First you'll want to confirm which version their standards are for and follow their instructions.
As far as learning to configure MicroStation there is training available on our Learn site:
