Most of my ideas for trying things in Revit either come from things around me, which I see on a day to day basis or from example of designs that others have created. My latest experiment comes from a design which appeared on the HOK Life blog. It actual a stool designed by Bram Geenen a designer based in the Netherlands who was inspired by Gaudi. I loved the form so much I wondered if was possible to create in Revit?
I started by attempting to build the form in one massing family, which sort of worked, but it was challenging getting all the parameters to work as I wanted. So I tried an approached I have used in the past of creating the family, setting up a rig of reference lines and parameters, I then saved this family. The original family was then copied and I add geometry to the copied families reference line rig. This was then loaded back into the original family where I then just linked the parameters together, so the master family was able to drive nested parameters. If you look below this is the original master family.
I then added some reference lines and tied the parameters from the form to loose labelled parameters which allowed me to interactively modify the form. I actually found creating a separate view to just allow me to adjust the loose labelled parameters a useful trick.
If you are interested, the family can be downloaded from here.
