So, I’m creating lists of revit parameters for export to excel. Some of my parameters contain unit notation (m, m^2), which I want removed or replaced with “0”. Unfortunately, all of the replace/remove nodes that I’ve seen are for strings, not lists. I can imagine two approaches:
The “a” acts as a variable that can be filled by the input it generates in the Formula node. One of the handy features of the Formula node is that it completely ignores units. That’s why you can use it to strip units.
With regard to your other question about the units of parameters pulled from a Revit element - I am on the 0.7.5 release candidate and everything I receive is in metric.
Generally, units are still a rather tricky subject in Dynamo. Have a look at these threads for more fun with units:
