I’ve been trying to develop a code to create a material with specified color, based on the one shown here . What I need is to create the material but, if it already exists, use the existing one (or override its color, ideally). I’ve created a Dynamo / Python routine for it, verifying the existence o…

Shane, I believe this script will help you achieve what you want: #Create or Update Materials based on List inputs import clr clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * clr.AddReference('RevitServices') import RevitServices from RevitServices.Persistence import DocumentManager fr…

did you ever get a solution to the problem you were having? I am trying to write a similar script where the database originates from a text file, but i would like the data to update! I get the following error Exception: The given value for name is already in use as a material element name. Para…

Hi, Shane, I’ve dropped this approach and went for a easier method. Instead of creating /checking the material every time the script ran, I copied the materials that existed in a template file I had set up previously (see the image bellow) [Capturar] Note: I don’t remember the exact package the Doc…

@David_Doria thank you! this is exactly what I was looking for! I am hoping to expand this to include thermal and physical properties ( we do a lot of building physics analysis ), I’ll let you know how I get on !

So… I was able to expand the script to include all of the data on the Identity Data page except for the Material Class has anyone any idea where in the Revit API this value is located? it is the only parameter left on this page that I can’t find. [image] i have also started looking at adding the…

Shane, as it can be seen here the Material’s Class is a property of it, such as Color, not a Parameter. Try to set it with something like new_mat.MaterialClass(string) and check if it works. About the Thermal Conductivity parameter, I believe your problem lies in the nature of the Thermal Property…

Shane, This is awesome. Was wondering, how would you assign color to a surface pattern and for that matter a surface pattern to a material? Haven’t been able to assign either with success… Looking forward to your input! Marco J

Marco, The code below will achieve your goal, I believe. #PROTO_Material Creation / Management v2 (Color and Surface Pattern control) # by David Dória import clr clr.AddReference('RevitAPI') from Autodesk.Revit.DB import * clr.AddReference('RevitServices') import RevitServices from RevitServices.P…

Hi @David_Doria I have tried your code and it works with the code block input. But i’ve got an excel file with names of materials, patterns and colours. And I would like for these to be the input for the code. The information is currently in a List format with the colour being the output of the Co…

Inering, you should use the Data.Import.Excel node. I have updated the Python code to facilitate reading the RBGs from a string formatted as “0,0,0” in Excel. Use the images below to create your own routine. #PROTO_Material Creation / Management v2 (Color and Surface Pattern control) # by David Dór…

Thank you for your response @David_Doria. One of the drivers for trying to create this script would be the ability to update the material library in new projects or update the parameters of materials in existing projects. See my thread below
