Tutorial: Simple Parametric truss in Revit with Dynamo

[@nicolasramirez3944]

Nice! How do you find coordinate locations in Revit? Perhaps I don't want a truss placed in space but at a particular connection between two already placed columns. Is there a way to obtain those coordinates? Or is there a dynamo select column>curve>endpoint>get coordinates procedure? Thanks for these videos btw!

Yes sounds like you are on the right track. If you use column>curve>endpoint>get coordinates you can use those to create a starting point for a new script (rather than 0,0,0).

Thanks for the great tutorial! How would I go about having an option for two different steel section types: Type 1 for top & bottom chords, and Type 2 for diagonals & verticals?

Cheers - thanks for the feedback! You could do that by keeping the top/btm chords in a separate list to diag/verts and then using two StructuralFraming.BeamByCurve nodes. Or you could make a list of sizes in the right order to give StructuralFraming.BeamByCurve at the end (if you have 16 members, make a list of 16 sizes).
