Location of wall's center of corecenter line

[Ke2king]

Hi everyone,
I’m finding way to get location of wall’ s corecenter line.
Doesn’t Dynamo have node for it?

Thank you.

Hi @Ke2king,

You can retrieve the location of the CoreCenter Line like this :

I think the Get Wall Layer Location Lines of Bakery package can also be found here :

Wall location curve

@john_pierson Two Clockwork nodes, an Archilab node, and a single code block to get interior, exterior, interior core face, and exterior core face from a wall. If anyone wants to include it in a package feel free. get wall faces.dyn (12.3 KB) {wallcurves,direction,walltypes,Widths,cores}; /* get the distance from wall location (centerline) to the exterior face of wall*/ distance = walltypes.GetParameterValueByName("Width")/2; //get the curves at the exterior face ExtFaceCurves = wallcurves.…

@Ke2king, or you can try this;

import clr
clr.AddReference('RevitAPI')
clr.AddReference('RevitNodes')

# for geometry conversion
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
from Autodesk.Revit.DB import *

# wall input
walls = IN[0]

# make list
if isinstance(walls,list):
	walls = UnwrapElement(walls)
else:
	walls = UnwrapElement([walls])

#output
centerLines = []

# loop wall
for wall in walls:
	# collect center line
	centerLines.append(wall.Location.Curve.ToProtoType(True))
	
OUT = centerLines

@jean,

The reuslt of your script is identical to the Element.GetLocation node.
I’m not sure that’s what OP is looking for.

@Alban_de_Chasteigner thanks mate , good to know OOTB has a node for that.

Hi @Ke2king ,
I would suggest something similar to what Alban said, minus the bakery node. I’ve had several instances of it not actualy returning the correct exterior/interior core lines.

Thank you for your cooperation.

That’s what i wanna do.
But can you check the following?

I think that Get Wall Layer Location Lines isn’t correct.
I don’t know why it is different after copying from the Bakery node.
After copying it’s correct.

↓OK

Thank you for your help.
And it’s solution.

Thank you again.

Thank you everyone!!

[bernhard.keppler]

any chance to report those to shared parameters?

[Ke2king]

Sorry, I don’t understand your question exactly.
However, you may be able to use “Element.SetParameterByName” node.
Thanks.
