Hi everyone,
I have tried all the topics in this forum related to geometry location and I couldn’t find the solution… I can get the project base point coordinates and the true north rotation value, and the distance from the pile location from the project base point, but it’s not a simple sum becaus it is differente vectors, so i need to discover how to sum this values to have the true coordinates value.
Can someone help me? Here is the image of the dynamo scrip so far…
If this is about survey CS and rotation something like that?
But it´s easier to use a total transform node:
Or this code:
import clr
import math
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import FilteredElementCollector, BuiltInCategory, BuiltInParameter, XYZ
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
from Autodesk.DesignScript.Geometry import Vector, CoordinateSystem
doc = DocumentManager.Instance.CurrentDBDocument
pbp = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_ProjectBasePoint).FirstElement()
pbpEW = pbp.get_Parameter(BuiltInParameter.BASEPOINT_EASTWEST_PARAM).AsDouble()
pbpNS = pbp.get_Parameter(BuiltInParameter.BASEPOINT_NORTHSOUTH_PARAM).AsDouble()
pbpElev = pbp.get_Parameter(BuiltInParameter.BASEPOINT_ELEVATION_PARAM).AsDouble()
# Angle from the parameter is in radians, converting it to degrees
pbpAngle = pbp.get_Parameter(BuiltInParameter.BASEPOINT_ANGLETON_PARAM).AsDouble()
pbpAngle = math.degrees(pbpAngle)
# Creating Dynamo Point
pbpPoint = (XYZ(pbpEW, pbpNS, pbpElev)).ToPoint()
# Creating Dynamo CoordinateSystem with rotation
xAxis = Vector.ByCoordinates(1, 0, 0)
yAxis = Vector.ByCoordinates(0, 1, 0)
origin = pbpPoint
# Rotating the vectors
xAxis = xAxis.Rotate(Vector.ByCoordinates(0,0,1), -pbpAngle)
yAxis = yAxis.Rotate(Vector.ByCoordinates(0,0,1), -pbpAngle)
# Creating the CoordinateSystem
coordinate_system = CoordinateSystem.ByOriginVectors(origin, xAxis, yAxis)
OUT = coordinate_system
The Revit internal and project coordinate systems are aligned so I’m pretty sure you do not need to rotate. Survey coordinates have rotation and I haven’t been able to work that out see next post
