Set correct structural usage in a completed model

[PCISAAC]

I work for a contractor and need to identify the structural usage of each structural framing member (girder, purlin, joist, etc.) in a structural model provided by a project's EOR.  In a perfect world, the EOR's modeler would have assigned the correct usage to each member.  I find though that this isn't always the case.  I could go through and assign them myself so I can run my analysis, but on a 40-50 story high-rise, that's going to take some time.  Is there a way I can filter down to what I'm looking for?  Say for girders, I filter down to only those that connect to columns or shear walls, and for joists, only those that connect to girders, etc.?  Then I could look for any anomalies, select the rest and assign the proper usage in my copy of the model.  I tried looking to set up a filter like that, but am not seeing parameters that resemble what I'm looking for.  Or is there another way to have the system assign their usage?  Or am I just plain SOL?  I'm open to Dynamo solutions as well.

I don't think there are any parameters to filter something like that, also dynamo works on the information provided by Revit, if the framing members does not have any parameter that differentiates between girder and joist, dynamo won't be able to help also. 
You have to do it manually or if there is a large difference between joist and girder sizes/type. you can create a schedule and change them that way.

Hello,

you can try plugin "one filter" from Diroots to select object by section/specific parameter

and after assign structural role.
