Practical ideas for Revit, BIM and construction technology. Built from years of shared experience.
Let’s say you have a family that has shape handles for instance dimensions (Length Parameters). What if you want to use it for quick prototyping, and then switch that same family into a version that u…
I once built an auto-sizing Fire Pipe Fitting using a Formulaic method (where the various fitting sizes were driven by the Revit intersection variable), so I was interested to read about a similar str…
Typically when editing Revit families, if you want to deal with arrays and stop them breaking when the count is 1, you set up some IF() formulas in Revit. However, a recent comment by David over on Re…
Mehmet Polat Diker has been busy doing some interesting Revit things over at Red Hot BIM. Like this little family that takes two dates and checks if the “deadline” has past or not. Some pretty detaile…
Chris Price has been pushing the limits. Check it out:“What I found was Revit would crash at around 580 conditional statements in a single formula… Surely Autodesk should know someone would try and do…
Nice tip from Revit Rants on how to round values within a family – and it allows much greater flexibility as to the rounding increment. In the example below, Chris uses ROUNDUP to round to a 5mm degre…
A couple of formula tricks from the CAD Shack: Pick One and Only One Here the condition number will allow only one paramter to be true in a list. Associated with a type, you could control a ton of th…
This is an example of an family with an array that kinda mimics a curtain that opens and closes. http://revitlog.nl/images/stories/families/82_meubels/82_gordijn.rfa However – it is also a good exampl…
It is currently not possible to evaluate a text string in a conditional statement. You can have a conditional statement report a text string, but not check text and base a condition on it.via RevitCit…
