Hello,
I want to project the analytical model of the column with two axes (Y and Z direction), I wanted to do these manipulations with Python, do you have any ideas? Thank you so much.
please who can help me 
Hi @brahimlabbassi,
here is some python code that pretty much does your whole script…
AnalyticalStickModel.SetAligmentToGrids (Py)
##### Imports #####
import clr
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
clr.AddReference("RevitAPI")
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB import Structure as ST
##### Definitions #####
# Ensures object is always in a List...
def tolist(obj1):
if hasattr(obj1,"__iter__"): return obj1
else: return [obj1]
##### Inputs #####
ams = tolist(UnwrapElement(IN[0])) # Analytical stick model elements...
gridY = tolist(UnwrapElement(IN[1]))[0] # The Grid you want the Y Projection to be aligned to...
gridZ = tolist(UnwrapElement(IN[2]))[0] # The Grid you want the Z Projection to be aligned to...
##### Outputs #####
outList = [] # The element output...
report = [] # The success report...
##### Main Script #####
# Open a new Transaction as we are making changes to an Element...
TransactionManager.Instance.EnsureInTransaction(doc)
# Loop through all the analytical stick model elements...
for am in ams:
try:
# Set Alignment Method for both Base and Top to be by projection...
am.SetAlignmentMethod(ST.AnalyticalElementSelector.Whole, ST.AnalyticalAlignmentMethod.Projection)
# Set Projection for Y and Z to be the gridY and gridZ Plane respectively...
am.SetProjection(ST.AnalyticalElementSelector.Whole, gridY.Id, gridZ.Id)
# output results...
outList.append(am)
report.append("Success")
# Catch any exceptions...
except Exception, ex:
outList.append(None)
report.append("Failed: " + ex.message)
TransactionManager.Instance.TransactionTaskDone()
# return user results to Dynamo Workspace...
OUT = outList, report
Note: I am using the actual methods for the AnalyticalStickModel rather than setting the parameters. But you could also set the Parameters too, but it’s better like this.
You can find the methods I used in the Revit API Inline Documentation…
