Line.ByStartPointDirectionLength (Revit API)

Hello,

We all recognize this node:

My question to you is if any of you know if there is an equivalent function in the Revit API.
Or possibly how to achieve the same result but in a different way.

I have searched but can not find a method that replaces the ByStartPointDirectionLength node.

Best regards,
Mikael

You could create the line with that node, then convert the line that is created into a revit line?

An example

import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
#import Revit API
clr.AddReference('RevitAPI')
import Autodesk
from Autodesk.Revit.DB import *
import Autodesk.Revit.DB as DB

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

def lineDB_ByStartPointDirectionLength(pta, vector, length):
	vector = vector.Normalize() * length
	return DB.Line.CreateBound(pta, pta + vector)
	
startPoint = XYZ(1,1,1)
vector = XYZ(1,3,0)
length = 3
line = lineDB_ByStartPointDirectionLength(startPoint,  vector, length)	

OUT = line, line.ToProtoType()

Thank you @c.poupin !

That was the solution I was looking for :slight_smile:
