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’m 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
EXCELENT
Awesome Tutorial.
Thank you very much
excellent tutorial! i teach revit in new zealand and wish i could make it seem as easy as you do.
Great tutorial! Am looking forward for more of the same!
very interesting technique..
I was trying to experiment with this technique but using a sweep blend with a cureved 2d path which proved to be more challenging. but then I realized I can use a curtain system by face to do it (create curtain system with only one grid pattern) . I think it would work just as well for what you have created here as well.
After reading the article, I feel that I really need more information on the topic. Could you suggest some resources ?
This was a really cool approach. Is there still going to be a Part II? Look forward to it.
it’s been a year, where’s the follow up? =)
Thanks for this. I followed your example using a line based template and it worked fine. From the comments above, this should work with a generic template using extrusions?
I want to use this for making precast concrete slabs with intermediate beams. You mention in the tutorial that you can add a formula for spacing on center. I would really like to learn more about this.
Hi,
The video is not working. any hints ? have you checked recently ?
regards
works for me
