Element color override in viewS

Revit
11

Here’s an example of a Python script that overrides Tags by view. Keep in mind that list of Elements and list of Views have to match in length.

Here’s Python script:

import clr
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument

clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *

import sys
pyt_path = r'C:\Program Files (x86)\IronPython 2.7\Lib'
sys.path.append(pyt_path)

def ConvertColor(e):
	return Autodesk.Revit.DB.Color(e.Red, e.Green, e.Blue)

def OverrideColorPattern(e, c, f, view):
	gSettings = OverrideGraphicSettings()
	gSettings.SetProjectionLineColor(c)
	gSettings.SetProjectionLinePatternId(UnwrapElement(f).Id)
	UnwrapElement(view).SetElementOverrides(UnwrapElement(e).Id, gSettings)
	return e

try:
	errorReport = None
	TransactionManager.Instance.EnsureInTransaction(doc)
	
	c = ConvertColor(IN[1])
	output = []
	for i, j in zip(IN[0], IN[3]):
		output.append(OverrideColorPattern(i, c, IN[2], j))

	TransactionManager.Instance.TransactionTaskDone()
except:
	import traceback
	errorReport = traceback.format_exc()

if errorReport == None:
	OUT = output
else:
	OUT = errorReport

Obviously I just did lines because I was overriding tags, so they don’t have solid geometry, but for someone who wants to override walls, you might want to also add surfaces to the override routine. The API is referenced here:

https://apidocs.co/apps/revit/2020/bd467fbb-a9da-7cf1-1ef5-f0f3568db0ac.htm

It’s a different API for Revit 2020 which is what I am using for demonstration above. Keep in mind that some older methods available in 2017 or 2018 were removed in 2020.
