Color - how to get channels from overrideGraphicsSettings

[Tomasz_Puchala]

Hi,
I’m trying to get 3 channels from Autodesk.Revit.DB,Color and I’m really stuck
Basically I’ve got lists: overrideGraphicSettings -> get for example CutLineColor -> get Red,Gree,Blue
Error:

Last script:

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

colors = UnwrapElement(IN[0])
r,g,b = [],[],[]
OUT = []
for i in colors:
	r = i.Red
	g = i.Green
	b = i.Blue
	color1 = Autodesk.Revit.Creation.Application.NewColor(r,g,b) #First attempt
	color2 = Autodesk.Revit.DB.Color(r,g,b)	#Second attempt
	OUT.append(color1)
	OUT.append(color2)

Are you simply converting from revit color to dynamo? Clockwork has some nodes for this.

[Tomasz_Puchala]

Yeah, but sth is wrong

Hi @Tomasz_Puchala

Try this:

Hi, still no luck.
Attached rvt 2015, and dyn 1.0.0
COLOR_TEST.rvt (1.2 MB)
FILTERS_TEST.dyn (15.8 KB)

[Tomasz_Puchala]

Any ideas?

Hi @Tomasz_Puchala
Looks like the issue is coming from the color you’re feeding:

Yeah it looks like, do you know how to get color overrides from filters in view Template or just element? I always get invalid colors no matter what I do. There is sth like invalidColorValue that throws “-1” everytime.
Thanks

The reason why you are getting -1 is because the colours aren’t valid.

You could try this. It gets all the filters assigned to each view and then gets the filter overrides projection line colour and returns a Dynamo colour object if its valid:
