Export dwg setup

Revit

@BIMadmin Here is a working Python script to get the information on the Layers tab in the Modify DWG/DXF Export Setup window:

dwg%20export%20settings
dwg export settings.png842×398 18.1 KB 

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

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

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager

doc = DocumentManager.Instance.CurrentDBDocument

settings = IN[0]
if not isinstance(settings,list):
	settings = [settings]

def getExportInfo(set):
	cattype = []
	category = []
	subcategory = []
	colorname = []
	colornumber = []
	cutcolornumber = []
	cutlayername = []
	layername = []
	options = set.GetDWGExportOptions()
	table = options.GetExportLayerTable()
	keys = table.GetKeys()
	for key in keys:
		category.append(key.CategoryName)
		subcategory.append(key.SubCategoryName)
	layerinfo = table.GetValues()
	for i in layerinfo:
		cattype.append(i.CategoryType)
		colorname.append(i.ColorName)
		colornumber.append(i.ColorNumber)
		cutcolornumber.append(i.CutColorNumber)
		cutlayername.append(i.CutLayerName)
		layername.append(i.LayerName)
	return zip(cattype,category,subcategory,layername,colorname,colornumber,cutlayername,cutcolornumber)

exportSettings = [getExportInfo(UnwrapElement(i)) for i in settings]

OUT = exportSettings

You’ll notice this output is not sorted by Category Type or Category so you’ll want to do some post processing (either in Dynamo, which I’d recommend for practice, or in Excel when you’ve exported it).

To get the information from the Lines and Patterns tab, you’d follow a similar workflow with the relevant API methods. This script is a bit more complex because it is made to work for a single DWGExportSettings element or a list; I hope it helps!
