Dimension to face reference and element

Revit

Hi,

I’m trying to combine the two methods of automatically dimension in Dynamo. I can dimension element to element using “Dimension.By.Elements” node. And I can dimension face to face using this python script

Is there a way to combine the two, i.e. Dimension to a face and an element.

Thanks in advance

Hi Mostafa,

Thanks for your reply

Here is the code that works for Face to Face dimensioning

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

clr.AddReference("RevitNodes")
import Revit

from Revit.Elements import *

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

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

dataEnteringNode = IN

doc = DocumentManager.Instance.CurrentDBDocument

line = UnwrapElement(IN[0]).GeometryCurve
elements=(IN[1])
dim = 0

elementsRef = ReferenceArray()
opt=Options()
opt.ComputeReferences=True
opt.IncludeNonVisibleObjects=True
opt.View=doc.ActiveView
for element in elements:
	elementsRef.Append(element)
TransactionManager.Instance.EnsureInTransaction(doc)

dim=doc.Create.NewDimension(doc.ActiveView, line, elementsRef)
(True)

TransactionManager.Instance.TransactionTaskDone()

OUT = dim

And here is the one I am working on now to try and dimension from a floor edge to a grid line

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

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

from Revit.Elements import *

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

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument

line = UnwrapElement(IN[0]).GeometryCurve
grid = UnwrapElement(IN[1])
elements=(IN[2])
dim = 0

geomopt=Options()
geomopt.ComputeReferences=True
geomopt.IncludeNonVisibleObjects=True
geomopt.View=doc.ActiveView

refg = []
for i in grid:
	r = i.get_geometry(geomopt)
	[refg.append(j.Reference) for j in r if str(j).contains('line')

for j in elements:
	elementsRef.Append(element)

dim = []
TransactionManager.Instance.EnsureInTransaction(doc)
for i,j,k in zip(refg,elementsRef,IN[0]):
	refarr = ReferenceArray()
	refarr.Clear()
	refarr.Append(i)
	refarr.Append(J)
	dim.append(doc.Create.NewDimension(doc.ActiveView,k.ToRevitType(),refarr))

TransactionManager.Instance.TransactionTaskDone();

OUT = dim

It is actually a variant of something you posted on another discussion

Any help from you at all would be greatly appreciated

Could you please paste your code as preformatted text like @Mostafa_El_Ayoubi mentioned above? It will be easier for users to help troubleshoot for you without having to indent all the code. :slight_smile: also what is the error that is appearing when you run it?

I think he doesn’t know how to do that but i had edit his code. Looks good now :slight_smile:

Thank you @Kulkul. I’m new to posting here.

Essentially I know how to dimension from element to element, for example, gridline to the centre of a wall, column etc. I also have some python code that will dimension from the face of a wall to a face of wall. But now I’m trying to figure out how to tweak this python code to dimension from a gridline to a face of a wall. Does that make sense?
