Hello! I’m working on my master thesis where one of my objectives is to color code certain elements depending on how certain project parameters fall within value intervals. This meaning, for example, if a parameter has a value between 1 and 2 it colors green, between 3 and 4 orange, between 4 and 5 red. If anyone can help it would be very appreciated! I’m new to dynamo and sort of new to Revit, and I’ve been teaching myself to get through my thesis but in this aspect I’m a bit stuck…
Yes I have been searching the forum for a few days and came up with some similar problems to mine but no quite enough in order for me to pull something for my work
I will check out the Pugin, thank you for your help!
To get a hang of things with dynamo try the dynamo primer:
Above posted link provides a simple way of doing it via dynamo.
It will need to be adapted to your parametername and element category. So in essence to your project.
Try to get it going by yourself and if you get stuck somewhere on the way feel free to respond here again.

Hi,
i am facing issue in the above code given by c.poupin
can someone share what code is written for colors interval ?
and also explain explain me this how this actually works ?
Thank You
