Revit - Parametric Truss System - Part 1
Software : Revit Architecture
Level : Intermediate
Description : This Revit video tutorial shows how to array a series of voids to create a changing truss system. Rather than thinking of the modeling in components what we are doing here is modeling a solid and using Revit’s cut geometry tool to slice a solid into stick members. The only catch to this techniques is that each truss has a slight slant on the top and bottom. This is something that i willing to look past since i figure it will be lost in the line weight. Once this model needs to transfer to a higher lever of precision i would consider another modeling technique. As a design tool this technique allows for quick iteration while maintaining the design intent. This is the first part of a two part series the second video will dive deeper in using formulas to drive the spacing and thickness of trusses (and why it’s in a line based family:)).

That’s Awesome!! Thanks!
Thanks! I’m going to do the follow up to this soon.
Hey David, awesome!
I did try to apply the same concept to a simple extrusion in Revit Architecture 2008, and everything was fine, except for the possibility to adjust the initial profile dynamically, as you
do here.
If I try to modify my initial profile, I get an error message saying that the initial constraints
are not satisfied. Maybe I did some mistakes in modeling that part. I just draw a profile, locking
as you do, offset, close the profile….. and then extrude along a path.
Let me know if my problem is understandable, maybe I should have posted
this in the new forum ?

hmmm. Maybe post your file in the forum and i can take a look at it. But from what i understand, it should be working.
great tutorial. I’m impress with the potential of revit
