Trying to create wall by levels using python

2

Hey,

This works for me… There were things that were right and a few things to change, I would look at the Clockwork and Archi-lab nodes to see how they are working.

Hope that helps,

Mark

P.S. when pasting code, please use image to format it

#thanks to clockwork and Archi-lab

clr.AddReference('RevitNodes')

import Revit
clr.ImportExtensions(Revit.Elements)
clr.AddReference('RevitServices')

clr.AddReference('RevitAPI')

doc = DocumentManager.Instance.CurrentDBDocument

baseLevel = UnwrapElement(IN[0])
topLevel = UnwrapElement(IN[1])
wallType = UnwrapElement(IN[2])

pt1 = XYZ(0, 0, 0)
pt2 = XYZ(10, 0, 0)

TransactionManager.Instance.EnsureInTransaction(doc)

line = Line.CreateBound(pt1, pt2)
wall = Wall.Create(doc, line, baseLevel.Id, False)

#we need to get an id from the type to use in setting the type, this must be an integer, to make an integer we need to convert the id to a string first
typeId = int(str(wallType.Id))

#change type, this needs an element id which is defined by the typeid
wall.ChangeTypeId(ElementId(typeId))


#to isolate the built in parameter we want, we first get all of them, then add the one which matches the name to our list.
builtInParams = System.Enum.GetValues(BuiltInParameter)
for i in builtInParams:
	if i.ToString() == 'WALL_HEIGHT_TYPE':
		bip = i
	else:
		continue
		
#as above we need an id from the top constraint to set the parameter value
topLevelId = int(str(topLevel.Id))

#we first get the wall parameter then we set it 
wall.get_Parameter(bip).Set(ElementId(topLevelId))


TransactionManager.Instance.TransactionTaskDone()

OUT = wall,
