Structural question.

[Joef]

Does the Revit structural framing system differentiate between dimension lumber and structural steel when deciding how structural elements appear in your drawing?

[Tom Weir]

Not exactly sure what you are getting at here. In course view, beams are displayed by their function, i.e. girder, joist, purlin etc., as a stick symbol with various user-defined widths. Whethor it is wood or steel it is still a beam.

Does the Revit structural framing system differentiate between dimension lumber and structural steel when deciding how structural elements appear in your drawing?The families themselves define how they appear. The wood-frame families and the steel families both have different defined appearances at coarse, medium and fine detail levels. At coarse detail you only get the think black line for framing diagrams and at medium you get the actual physicality of the object. Some families go a step further to show the filleting of the steel beams at the fine detail level.

So it's more about how the families were constructed in the first place.

Does this help?

I'm attempting to figure out the relationship between where you draw a joist/beam system and where Revit displays it. There is a reason the joists do not appear where they logically ought to and I am thinking is because the logic is based on structural steel not dimension lumber. A steel beam usually has a bolted connection so it doesn't need to be shown butted against its connection. This is how Revit displays it. Dimension lumber is not bolted and needs to be shown differently.
