I am working on a script which gets (2D) Civil3D Blocks into Dynamo to turn them into 3D Civil3D Objects. The problem which i am facing right now is that PolyCurves which intersect with other PolyCurves which are already Closed, see image below:
This wouldnt be a problem if i could just Close the Blue Polycurve, except i cant do that because i have other Objects in my file which look like this: (As you can see the Surface is wrong)
I think the solution here lies with the fact that in the first screenshot the lines are not connecting at their start- or endpoints but they are at the second image. But i dont know how to group Curves only by their start- and endpoints
I hope i was clear enough, and that someone knows a good way to approach this
Try a group curves node from Archi-lab. It may not load in C3D but last I checked it was a custom node which means you can copy / paste the contents D4R to add the code to your graph, save the graph, and open it in C3D to get the good stuff.
I don’t know how to solve/ approach this because i don’t know a lot about Python.
The Script:
#Copyright(c) 2015, Konrad Sobon
# @arch_laboratory, http://archi-lab.net
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
#The inputs to this node will be stored as a list in the IN variable.
dataEnteringNode = IN
inputCurves = IN[0]
#join/grou p curves function
def groupCurves(Line_List):
ignore_distance = 0.01 # Assume points this close or closer to each other are touching
Grouped_Lines = []
Queue = set()
while Line_List:
Shape = []
Queue.add(Line_List.pop()) # Move a line from the Line_List to our queue
while Queue:
Current_Line = Queue.pop()
Shape.append(Current_Line)
for Potential_Match in Line_List:
Points = (Potential_Match.StartPoint, Potential_Match.EndPoint)
for P1 in Points:
for P2 in (Current_Line.StartPoint, Current_Line.EndPoint):
distance = P1.DistanceTo(P2)
if distance <= ignore_distance:
Queue.add(Potential_Match)
Line_List = [item for item in Line_List if item not in Queue]
Grouped_Lines.append(Shape)
return Grouped_Lines
OUT = groupCurves(inputCurves)
I Think the error has to do with the fact that i am feeding nested lists into this Python script.
But i dont know how to change this script to also accept nested lists
