How to create a Slanted wall with Revit API?

Question

Im trying to develop script for myself in dynamo(Revit 2021), but I don't understand how can I create the slanted wall? According to this blog of changes in revit 2021, there are such parameters for creating inclined walls as BuiltInParameter.WALL_CROSS_SECTION. However, there are no examples of using them to existing parameters or classes. Therefore, I do not understand exactly where to use it at the stage of creating a line or wall and what should be the appeal?

The part of the code where the wall itself is created, in the end I tried to turn to the wall and change its orientation parameter to an inclined one, because there are no other appeals.

import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

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 *

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion) 
# points for line
p_tp_1_1 =  XYZ(x_tp_1_1, y_tp1, levels.get_Parameter(BuiltInParameter.LEVEL_ELEV).AsDouble() + size_of_batten_1v_width)
p_tp_1_2 =  XYZ(x_tp_1_2, y_tp1, levels.get_Parameter(BuiltInParameter.LEVEL_ELEV).AsDouble() + size_of_batten_1v_width)
# Draw a line
wall_line_tp1 = Line.CreateBound(p_tp_1_1, p_tp_1_2)
# Create a Wall
wall_tp1 = Wall.Create(doc, wall_line_tp1, type.Id, levels.Id, h_tp_1, z_tp1, 0, 1)
wall_tp1.Orientation(BuiltInParameter.WALL_CROSS_SECTION(1))

If there is anyone who has encountered this, the example can be in C++ or c#, I will try to adapt it in python. And thanks for any help.

Answer 1

As I mentioned in my answer to your question in The Revit API discussion forum , here are some API samples and updates from The Building Coder that may be of use:

• The FaceWall Class and Slanted Walls
• Create FaceWall on Slanted Mass Face
• What's New in the Revit 2021 API: 1.9. Slanted Walls
• What's New in the Revit 2022 API: 2.1.4. Slanted and Tapered Walls

Answer 2

So I figured it out on my own. If anybody have the same question, there is a cod:

# Points
p_tp_1_1 =  XYZ(x_tp_1_1, y_tp1, levels.get_Parameter(BuiltInParameter.LEVEL_ELEV).AsDouble() + size_of_batten_1v_width)
p_tp_1_2 =  XYZ(x_tp_1_2, y_tp1, levels.get_Parameter(BuiltInParameter.LEVEL_ELEV).AsDouble() + size_of_batten_1v_width)
# Draw a line
wall_line_tp1 = Line.CreateBound(p_tp_1_1, p_tp_1_2)
# Create a Wall
wall_tp1 = Wall.Create(doc, wall_line_tp1, type.Id, levels.Id, h_tp_1, z_tp1, 0, 1)
# Here we get the parameter of the wall
cross_wall = Wall.get_Parameter(wall_tp1, BuiltInParameter.WALL_CROSS_SECTION)
# Set a value to the parameter ( 0 - slanted; 1 - vertical)
cross_wall.Set(0)
# assign the angle of the wall
angle_wall.get_Parameter(wall_tp1, BuiltInParameter.WALL_SINGLE_SLANT_ANGLE_FROM_VERTICAL)
# For example, we tilt it by 30 degrees: 
angle_wall.Set(0.30)
