Create a Cellular Beam Family - A Method - Part 1 - Shared Parameters & Catalogue
Shared Parameters
Create Shared Parameters as follows (parameter type shown in brackets):
Create Shared Parameters as follows (parameter type shown in brackets):
- Cell Pitch (Length)
- Cell Diameter (Length)
- Section Top (Family Type : Generic Model)
- Section Top Depth (Length)
- Section Btm (Family Type : Generic Model)
- Section Btm Depth (Length)
Catalogue
The cellular beam family here will be composed of sections from UK steel stock, UB (Universal Beam) sections and a catalogue of sizes will be required. At Waterman, we create our standard catalogues from scratch, using compiled information from the Tata/Corus Online 'Blue Book'. and extra parameter that we use (as opposed to the OOTB catalogues). These master catalogues are held as csv files, then copied and renamed to the appropriate family type catalogue txt file. For information on creating type catalogues, refer to the Revit help files. The type catalogue will drive parameters in the 'Generic Model Steel Half Beam Family'
Create a Cellular Beam Family - A Method - Overview
A few weeks ago, Glenn Jowett posted on his RevitST blog about the OOTB Cellular Beam Family.
I completely echo Glenn's sentiments and it reminded me of the issues we have had. We have had a workable alternative for some time, but it needed a little more development, which Glenn's post has prompted me to do something about. Also, that we should share this with the larger Revit community. The issues have been to get something that is both user friendly and has good model performance. Autodesk recommend economy when using voids, arrays and nesting in families, which unfortunately are required for this particular family to work. I will cover the aspects in different parts as outlined in the shopping list below to keep it manageable:
Brief
Create a cellular beam family. End user parameters to be limited to the Cell Pitch/Diameter and the section size top and bottom. Model performance must be managed in the right way
