MicroStation applications, MDL

Do we have a thread, that I have not yet located, for MicroStation CAD program, and applications to run MDL or similar programs.

Initial interest would be in a Mechanical tool that provides fasteners; steel shapes; welding symbols; geometric dimensioning and tolerancing; ANSI symbols, etc.

We had a program, but with later uSTN versions, it is not compatible.

I noticed Bentley had been incorporating a couple of the features, but not all.

Thank you in advance.
