Hi everyone, I’m a newcomer to the Bim/Revit/Dynamo world, so please excuse my ingenuity beforehand. My new task is to prepare about 5000 materials, which are pretty similar one to another. After a few days creating everything manually, decided give Dynamo a chance to do that for me. Did my (quic…

You’re right, I didn’t explain myself clearly. I’d like to set these with PythonScript: [revit-parameters] [revit-parameters-2] Saw one user setting them with Element.SetElementByName here: ( how-to-set-the-material-parameters-class-and-keywords ) and I thought it will be possible with python.

Identity tab stuff is doable. Well maybe not all of it but I know some of it is as that was my first ever script. Element.setparameterbyname is all you need so long as you feed the right elements (materials) and value types. The appearance tab you can’t touch unless you are in Revit 2018.1.

Trying to break through some mysteries here, I discovered some interesting things. I am on R2017 at the moment: First, the color of a material (the one from the Graphics tab) can be set with a simple Element.SetParameterByName node. The awaited value is an integer but I don’t know how this number …

[image] Yna_Db: The awaited value is an integer but I don’t know how this number is defined. I have been able to set a value from 0 up to 16777215 It’s based on the RGB values; 256 options per variable. [image] r = dynColor.Red; g = dynColor.Green; b = dynColor.Blue; integer = r+256*g+6553…

Any link to an additional resource about that, by chance?

Afraid not. It was just from experimenting with integers and the resulting RGB values. Here’s how it breaks down: Red takes up integers 0-255. Makes sense. Green starts at 256 but begins counting with the Red values. So 256 = [R=0,G=1,B=0] and 257 = [R=1,G=1,B=0] and so on. Blue starts at 65536 …

I think springnodes has a custom node for this.

using element unique id, you can set all parameter of materials [ej%20item]

Were you able to complete this script? I am trying to accomplish something similar where our material database is in excel!

Sorry for late response, but I’ve abandoned the idea of doing this with python and switched to c#. With VS you can connect directly to RevitSDK and contextual help there works very well.
