Hi There,
I have spent a few weeks trying to accurately calculate the surface area of duct fittings using native revit families. I have tried a few different options using both a python script as well as nodes and I can’t seem to get an accurate takeoff.
I have tried using element faces and surface area but I found this required me to add specific parameters to the families which might not always be an option.
I tried using a script to work out the material of each family but found this was out in terms of the square metres for objects.
Essentially I am trying to get as close a reading to Fab Parts as possible, especially with items like Square to Rounds which are a tricky geometry. I have read a lot of other posts about recreating and the element using dynamo but this seems a double up of work and again not always going to be an option.
I feel like I am probably missing something painfully obvious but my understanding of the API and dynamo are pretty limited.
Attached is a screenshot of the node graph I created which is close but doesn’t work for all geometry, as well as the 2 different python scripts which don’t seem accurate.
