Hello guys,
I would like to create automatic dimensions from visible parts of the railing. I can get the edges of element and their curves but it gives me null value as reference when I use curve.GetEndPointReference(0).
Why is it like that? I have to draw detail lines and get their references to create dimensions. In UI I can snap same points on element but why does not it work over API?

clr.AddReference('ProtoGeometry')
import Autodesk.DesignScript.Geometry as dscore
clr.AddReference("RevitAPI","RevitServices")

clr.AddReference("System.Core")
clr.ImportExtensions(System.Linq)

clr.AddReference("RevitNodes")

ansichten, elemente = UnwrapElement(IN)
opt = Options()
opt.ComputeReferences = True
opt.IncludeNonVisibleObjects = False
output=[]
TransactionManager.Instance.EnsureInTransaction(doc)
for ansicht, element in zip(ansichten, elemente):
temp =[]
opt.View = ansicht
geom = element.get_Geometry(opt)
for geomObj in geom:
instTransform = geomObj.Transform
symbolGeometrie = geomObj.GetSymbolGeometry()
for instObj in symbolGeometrie:
solid = instObj
if solid ==None or solid.Faces.Size==0 or solid.Edges.Size==0:
continue
for edge in solid.Edges:
curve = edge.AsCurve()
if isinstance(curve,Arc):
if curve.Radius>20:
startPoint = curve.GetEndPoint(0)
endPoint = curve.GetEndPoint(1)
startPoint = curve.GetEndPoint(0)
endPoint = curve.GetEndPoint(1)
transStart = instTransform.OfPoint(startPoint)
transEnd = instTransform.OfPoint(endPoint)
if transStart.Y<transEnd.Y:
line = Line.CreateBound(transStart,transEnd)
else: line = Line.CreateBound(transEnd,transStart)
temp.append(line.ToProtoType())
else: pass
else:
startPoint = curve.GetEndPoint(0)
endPoint = curve.GetEndPoint(1)

transEnd = instTransform.OfPoint(endPoint)
