A couple of releases back a set of Dynamo nodes were created to allow the connection between Dynamo and Advance Steel. A recent release sees this plug in upgraded for use with Dynamo 2.0.2.

The tools certainly look promising but could really do with a little more development. At present you can create members, add plates and custom properties which allows for the advanced modelling of members but limited control over connections and Advance Steel Properties.
The Dynamo for Advance Steel can be located on the Add-ins Ribbon as shown below.

Once Dynamo is running you will find the Advance Steel nodes shown below.

Steel members are created by providing a list of members start and end points and then a vector to describe the Section Orientation. Bear in mind that all Advance Steel members can be generated with the Beam tools. It would have been nice to be able to change the Model Role for each set of members as this would have increased the efficiency when creating larger frames with beams, braces, columns etc.

Most of the Dynamo Nodes are easy to understand but the defining the section to use can be a little tricky. The first stage is to locate the Advance Steel Profiles database. The quickest method is to launch the Advance Steel Management Tools and then open the installed databases. Filter this for the Profile Master Tables.

You will need to copy the TypeNameText of the section type that you require and Paste this into a Dynamo Code block or a String. Search the relevant table and then locate the SectionName required.

The TypeNameText and SectionName are then concatenated with a special code #@§@# which is used to separate the two strings. Your Code Block will look like the image shown below.

I tested the Advance Steel Dynamo nodes by creating the following space truss using the LunchBox tools.

The few nodes provided definitely show promise and with a little more development could really be useful. Of course, another option is to create the frame using Dynamo and Autodesk Revit and then export this into Advance Steel.
