I have not used prosteel but can throw some light on your Revit queries.
Revit has the capability of generating 2D drawings as extracted from AutoCAD., the only difference is that the basic extraction of details comes from the model. Revit maintains a single database for example if you model a steel column with base plate and foundation, this steel column will have some properties attached to it like its Type, size, material, etc. When you cut a section through it or on a plan you will be able to see the 2D output and also will actually be able to select the 3D model element in section view also. once selected in section it is by default selected in all other views(bidirectional). You can access its properties in any of the views and also enter information in any views, it updates for all views automatically.
Once the section is cut we can use annotations to detail the section and also use tags which can read the information from the element properties and display the information as annotation text, For example if you add a tag to the column to display its size and at a certain point the column size changes the tag would automatically read the new size and update the size annotation in the section view.
There are lot may things that Revit is capable of doing, though I should say there are some constraints. Constraints in the sence what we have made it for ourselves. From years we have been working the way of AutoCAD and now trying to impose the same way of working, standards on Revit, which is not the way it should be, as we are constraining ourselves from doing things differently.
Positively in the coming years we will have an efficient way of working with Revit and standard that meet our requirements.
Also let me know if I have answered you question and if you need to know any thing else.
