Toposolid points

Revit
1

Hello everyone,
I’ve been trying to extract topopoints, but since revit2024 is using toposolids now, dynamo (or atleast for myself) is not recognizing the toposolid as a topography to use with topopoints.
What is your solution.
Also, since toposolids are not sliced ( as previously in toposurfaces), and are subregioned, is it possible to extract points of that exact subregion of the toposolid.
Thanks

It seems the dynamo node only accepts old style topography - I would use a little bit of Python.

For the Subdivisons, you need a bit more.

import clr

# Import RevitAPI
clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *

# Import DocumentManager and TransactionManager
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager

doc =  DocumentManager.Instance.CurrentDBDocument

topo=IN[0]
output = []

profile = doc.GetElement(UnwrapElement(topo).SketchId).Profile

for obj in profile[0]:
    output.append(obj.ToProtoType())
    
OUT = output

But somebody probably made a package to do this already I suppose :wink:
TopoSubDivision.dyn (4.8 KB)

I haven’t seen much of package to do basic function as for the former topography, nor an OOTB package from Dynamo.

I wish that Dynamo kept up with Revit changes, as this complicated deployment on machines of users with basic knowledge of Dynamo

Slab shape editor can get the points.

import clr

# Add references to Revit and Dynamo libraries
clr.AddReference("RevitServices")
clr.AddReference("RevitAPI")
clr.AddReference("RevitNodes")
clr.AddReference("ProtoGeometry")

# Import namespaces for Revit
from RevitServices.Persistence import DocumentManager
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Architecture import *  # For Toposolid and Slab Shape Editor
from Autodesk.DesignScript.Geometry import Point  # For Dynamo points

# Custom function to convert Revit XYZ to Dynamo Point
def XYZToDynamoPoint(xyz):
    return Point.ByCoordinates(xyz.X, xyz.Y, xyz.Z)

# Access the current Revit document
doc = DocumentManager.Instance.CurrentDBDocument

# Get the Toposolid input from Dynamo (connected to IN[0])
toposolid = UnwrapElement(IN[0])  # Unwrap Dynamo element to Revit element

# Initialize an empty list to store the extracted points
toposolid_points = []

# Check if the input is a valid Toposolid
if isinstance(toposolid, Toposolid):
    # Get the Slab Shape Editor for the Toposolid
    slab_shape_editor = toposolid.GetSlabShapeEditor()
    
    if slab_shape_editor:
        # Get all control points (SlabShapeVertex) using SlabShapeVertices
        slab_shape_vertices = slab_shape_editor.SlabShapeVertices
        
        # Extract the position of each vertex and convert it to Dynamo Points
        for vertex in slab_shape_vertices:
            position = vertex.Position  # Get the XYZ position
            toposolid_points.append(XYZToDynamoPoint(position))  # Convert to Dynamo Point

# Output the list of points (or an empty list if no points are found)
OUT = toposolid_points

Honestly Revit can barely keep up with Revit these days as is.

Can’t even get a release date for 2025 Issues addin and 2026 is around the corner…

Python is definitely a necessary middle ground to access newer API or get around the Revit version tied Dynamo issues/limitations that pop up from time to time, given they don’t always fast track revit updates for the sake of Dynamo (at least, it seems).

Hi Vanman,
Please can you help me to write a similar script for Adding Points to existing Toposolid.

8

Look up topoalign. Good addin. Might solve it for ya quick

9

But can get help if needed. I just get AI to write stuff I need to do these days.

If yoy want to learn, this is the method to get the editor which manages the points:

This is the way to add points to it:

It works but something with units is wrong.

Here units are fixed:

import clr

# Add references to Revit and Dynamo libraries
clr.AddReference("RevitServices")
clr.AddReference("RevitAPI")
clr.AddReference("RevitNodes")
clr.AddReference("ProtoGeometry")

# Import namespaces for Revit
from RevitServices.Persistence import DocumentManager
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Architecture import *  # For Toposolid and Slab Shape Editor
from Autodesk.DesignScript.Geometry import Point  # For Dynamo points

# Custom function to convert Revit XYZ to Dynamo Point
def XYZToDynamoPoint(xyz, conversion_factor):
    return Point.ByCoordinates(xyz.X * conversion_factor, xyz.Y * conversion_factor, xyz.Z * conversion_factor)

# Access the current Revit document
doc = DocumentManager.Instance.CurrentDBDocument

# Get the Toposolid input from Dynamo (connected to IN[0])
toposolid = UnwrapElement(IN[0])  # Unwrap Dynamo element to Revit element

# Initialize an empty list to store the extracted points
toposolid_points = []

# Get the internal units ID for length
intUnitsId = doc.GetUnits().GetFormatOptions(SpecTypeId.Length).GetUnitTypeId()

# Conversion factor from Revit internal units (feet) to the current project units
conversion_factor = UnitUtils.ConvertFromInternalUnits(1, intUnitsId)

# Check if the input is a valid Toposolid
if isinstance(toposolid, Toposolid):
    # Get the Slab Shape Editor for the Toposolid
    slab_shape_editor = toposolid.GetSlabShapeEditor()
    
    if slab_shape_editor:
        # Get all control points (SlabShapeVertex) using SlabShapeVertices
        slab_shape_vertices = slab_shape_editor.SlabShapeVertices
        
        # Extract the position of each vertex and convert it to Dynamo Points
        for vertex in slab_shape_vertices:
            position = vertex.Position  # Get the XYZ position
            toposolid_points.append(XYZToDynamoPoint(position, conversion_factor))  # Convert to Dynamo Point

# Output the list of points (or an empty list if no points are found)
OUT = toposolid_points
