Get several parameters of one element to male a BOM

[Yoann OBRY]

Hi,

I'm working to extract some parameters value of Pipe Accessories in the aim of creating a Bill of materials (BOM). In dynamo I find how to do it but in RPS i have some problems with the  instance and type parameters wich are diffenrent classes.

For example I wand to have a dictionnary or list of list with :

Item 1 : Name,  Description; Size

Item 2 : Name, Description, Size

....

Do you have an idea of this process ?

Here is my script :

(code_cir is a shared parameter)

import clr

import System

clr.AddReference('RevitAPI') 

clr.AddReference('RevitAPIUI') 

from Autodesk.Revit.DB import * 

from System import Guid

code_cir = Guid(r'55934d0c-0246-4ce2-9bdf-57ed4244e11b')

app = __revit__.Application

doc = __revit__.ActiveUIDocument.Document

PA_Type = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_PipeAccessory).WhereElementIsElementType().ToElements()

PA_Instance = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_PipeAccessory).WhereElementIsNotElementType().ToElements()

print('Type Parameters:')

for PA in PA_Type:

  

# Get Type Parameter value

nom = PA.get_Parameter(

BuiltInParameter.SYMBOL_FAMILY_NAME_PARAM)

print nom.AsString()

desc = PA.get_Parameter(

BuiltInParameter.ALL_MODEL_DESCRIPTION)

print desc.AsString()

print('Instance Parameters:')

for PA in PA_Instance:

# Get Instance Parameter value

code_circuit = PA.get_Parameter(code_cir)

print code_circuit.AsString()

size = PA.get_Parameter(

BuiltInParameter.RBS_CALCULATED_SIZE)

print size.AsString()

Kind regards,

Yoann

Ok I finally find by myself by inspiring of my python script :-)

It was not easy for a RPS beginner like me, hope it will helps other people.

import clr

import System

clr.AddReference('RevitAPI') 

clr.AddReference('RevitAPIUI') 

from Autodesk.Revit.DB import * 

from System import Guid

code_cir = Guid(r'55934d0c-0246-4ce2-9bdf-57ed4244e11b')

app = __revit__.Application

doc = __revit__.ActiveUIDocument.Document

PAs = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_PipeAccessory).WhereElementIsNotElementType().ToElements()

for PA in PAs:

print PA.Id

# Get Type Parameter value

PA_type = doc.GetElement(PA.GetTypeId())

nom = PA_type.get_Parameter(

BuiltInParameter.SYMBOL_FAMILY_NAME_PARAM)

print nom.AsString()

desc = PA_type.get_Parameter(

BuiltInParameter.ALL_MODEL_DESCRIPTION)

print desc.AsString()

# Get Instance Parameter value

 

code_circuit = PA.get_Parameter(code_cir)

print code_circuit.AsString()

size = PA.get_Parameter(

BuiltInParameter.RBS_CALCULATED_SIZE)

print size.AsString()

print '-'*20

I just read again my post and I would say I was inspiring by using Dynamo (and not python) to find my solution in RPS.
