Unable to compute edge from curve : NO_CUR_BB -- no current bulletin board exists


@kennyb6 wrote this awesome python code to order things by closest to the next thing. However this Revit project is giving me this error. Unsure what it is if anyone can help.

Revit 2018.3 and Dynamo 1.3.4

# Enable Python support and load DesignScript library
import clr
from Autodesk.DesignScript.Geometry import *

# The inputs to this node will be stored as a list in the IN variables.
t0 = IN[0] # Wall Elements
t1 = IN[1] # Wall Centerpoints
t2 = [] # Final sorted list
t9 = [] # Final sorted centerpoints
t3 = [] # Start Point closest to t8
t8 = Point.ByCoordinates(-99999,-99999,0) # Point used as origin

for _subP,_subC in zip(t1,t0):
	_subT = []
	_Cen = []
	t3 = t8
	while len(_subP) > 0:
		t5 = []
		for i in _subP:
			t5.append(Geometry.DistanceTo(t3, i))
		t6 = min(t5)
		t7 = t5.index(t6)
		t3 = _subP.pop(t7)
	t9.append(_Cen) # Add t9 to output for sorted geom

OUT = t2

Unsure if its related but this node seems to be giving out on the floors as well

tests with the floors got same error

From what I can see here: https://github.com/DynamoDS/Dynamo/issues/6151 here: https://forums.autodesk.com/t5/autocad-mechanical-forum/no-current-bulletin-board-exists/td-p/5465286 and here: What is NO_CUR_BB -- no current bulletin board exists?

no one seems to know the error, how to reproduce it reliably, nor how to fix it? For the geometry failure on the floors, I have no clue either but I would double check each floor individually to see which one is giving the error.


I detached the model to start isolating the error. Ran the script on the detached model and it worked though :confused: who knows

Well, opened a new local on the central and it seems to have started working haha

Its back with a new project! Not entirely sure why… tried slicing parts but no luck
