I don’t understood how to change ToXyz converts the Dynamo point to Revit type.
please give me a suggestion. read below link.
Python 0.6.3 to 0.7.x Migration · DynamoDS/Dynamo Wiki · GitHub
i have solve this problem.
but new problem is the crop region is not set.
please help me solve this.

ViewCropRegionShapeManager.SetCropRegionShape(CurveLoop)
is an old method, try to replace by
ViewCropRegionShapeManager.SetCropShape(CurveLoop)

Thanks for your reply c.poupin
Can you give me a script add new method of View crop. because i am not a professional developer.
Many Thanks in Advanced
it is possible output as view.
Hello
an example with a wall

Thanks for your script, it’s working very well. 
I have one more condition add in script.
In wall which face get a paint material that side create a elevation view of the wall. Is it possible?
Yes it’s possible by several steps
1/ get all faces of the wall (with HostObjectUtils.GetSideFaces() method)
2/ get and check material Name for each face
materialFace = doc.GetElement(face.MaterialElementId)
if "myPaint" in materialFace.Name:
#...
#ToDo
3/ if True, return the curvloop of this face, and his FaceNormal vector to position the mark on the correct side of the wall
4/ create the marker
the direction of the wall must also be taken into account to calculate the correct angle of rotation of the mark
Thanks c.poupin for your reply,
for single wall its work properly, but whenever I try to run with multiple wall it show listed warning( see attached snip).
Please suggest me how to work with multiple walls.
Hello @robert12546358
@jacob.small has already responded to your request in this topic have you tried to follow his advice?
Note:
if you are a beginner avoid copying and pasting pieces of code this is not the best way to progress

Thanks @c.poupin
I want to learn Dynamo Python, from google I get Python for website an other thing only.
Please share if you have any source for Python language learning for Dynamo Python.
Much appreciate
