I try to create line using coordinate but it show these error AttributeError: 'type' object has no attribute 'CreateBound'

Hello @somphon
you have a conflict between 2 namespaces (Revit API , and Dynamo Proto API)

remove this if you don’t use it

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

or use an alias

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

Line1 = DB.Line.CreateBound(pt1, pt2)
