Set Layout of rebars to fixe number with Revit API

[REDO10]

Hi everybody,

This topic is related to the preor one How to create Rebar From Curves using Revit API and Python in which I want to group the rebars with the same length in a set and as shown in the image below

I tried to use the GetShapeDrivenAccessor() method as indicated in this exemple Error creating rebars from curves in python but I get error related to ArrayLengthand I dont know how to fix it

here my script:

Rebar Set

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

from System.Collections.Generic import IList, List

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

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)

doc = DocumentManager.Instance.CurrentDBDocument

# dynamo curves as input
geo = IN[0]
bar_type = UnwrapElement(IN[1])
host = UnwrapElement(IN[2])
vect = IN[3]

rebars = []
temp = []
for i, j in zip(range(0, len(geo)), range(0, len(vect))):
    curv = List[Curve]()
    for c, v in zip(geo[i], vect[j]):
        curv.Add(c.ToRevitType())
        TransactionManager.Instance.EnsureInTransaction(doc)
        rebar = Rebar.CreateFromCurves(doc, RebarStyle.Standard, bar_type, None, None, host, v.ToRevitType(), curv, RebarHookOrientation.Left, RebarHookOrientation.Right, True, False)
        rebar.GetShapeDrivenAccessor().SetLayoutAsFixedNumber(rebar.NumberOfBarPositions, rebar.ArrayLength, rebar.BarsOnNormalSide, rebar.IncludeFirstBar, rebar.IncludeLastBar)
        TransactionManager.Instance.TransactionTaskDone()
        curv = List[Curve]()        
        temp.append(rebar)
    rebars.append(temp)
    temp = []

OUT = rc

Please help me to solve my issue.

Thanks.

without a reply, I asked my question here and I get a steps to follow writen in C# as shown below, which I tried to convert to python…my containers are created but they are empty and I dont know where I was wrong??

rebar container in C#

public static RebarContainer CreateDistributedContainer(Document doc, Element host, List<Rebar> rebarList)
		{
			ElementId containerTypeId = RebarContainerType.GetOrCreateRebarContainerType(doc, "RebarContainerName"); // Container type id.
			RebarContainer rebarContainer = RebarContainer.Create(doc, host, containerTypeId); // Create rebar container.

			// Add rebars to cotainer.
			foreach (Rebar rebar in rebarList)
			{
				rebarContainer.AppendItemFromRebar(rebar);
			}

			// Update parameters.
			Parameter quantityParameter = rebarContainer.get_Parameter(BuiltInParameter.REBAR_ELEM_QUANTITY_OF_BARS);
			RebarContainerParameterManager containerParameters = rebarContainer.GetParametersManager();
			containerParameters.AddOverride(quantityParameter.Id, rebarList.Count);

			// The container.
			return rebarContainer;
		}

Please check my code and my screenshot below:

# dynamo curves as input

rebars = []
temp = []
for i, j in zip(range(0, len(geo)), range(0, len(vect))):
    curv = List[Curve]()
    containerTypeId = RebarContainerType.GetOrCreateRebarContainerType(doc, "circular_rebar" + str(i+1))
    rebarContainer = RebarContainer.Create(doc, host, containerTypeId)
    for c, v in zip(geo[i], vect[j]):
        curv.Add(c.ToRevitType())
        TransactionManager.Instance.EnsureInTransaction(doc)
        rebar = Rebar.CreateFromCurves(doc, RebarStyle.Standard, bar_type, None, None, host, v.ToRevitType(), curv, RebarHookOrientation.Left, RebarHookOrientation.Right, True, False)
        TransactionManager.Instance.TransactionTaskDone()
        curv = List[Curve]()        
    rebarContainer.AppendItemFromRebar(rebar)
    quantityParameter = rebarContainer.get_Parameter(BuiltInParameter.REBAR_ELEM_QUANTITY_OF_BARS)
    containerParameters = rebarContainer.GetParametersManager()
    containerParameters.AddOverride(quantityParameter.Id, curv.Count)    
    rebars.append(rebarContainer)
    
OUT = rebars

Thanks.
