Fire rating (1Hr, 2Hr.... etc) values for walls.

[Anonymous]

Hi,

I am looking for fire rating Value for Walls. i.e. 1Hr, 2 Hr etc.

I am able to see these values in "Wall-> Propertices-> Type Propertices" -> Identity data-> Fire Rating

But i want to get that value using .net  c# code.

Please tell me the method or any way so i get that value.

Please help!

Regards,

Nitin.

Nitin,

You should install an addin called BipChecker, which can be found here

http://thebuildingcoder.typepad.com/blog/2013/01/built-in-parameter-enumeration-duplicates-and-bipch...

Use this add-in to determine whether the parameter you are trying to access is a Built In Parameter, or a Shared Parameter.  You can also determine whether the parameter is stored as a string, integer, double or ElementId.

You can also use RevitLookup, which is an add-in included with the Revit SDK.

Element wallElement; (I'm assuming you already have the element available in your code)

FamilyInstance wallFamilyInstance = wallElement as FamilyInstance;

if (wallFamilyInstance != null)

{

//Note that we are accessing wallFamilyInstance.Symbol to access the parameter - this is because it's a type parameter

//If the parameter is a built in parameter, use the following line
Parameter fireRatingParam = wallFamilyInstance.Symbol.get_Parameter(BuiltInParameter.OST_YOURPARAM);

//If the parameter is a shared parameter, use the following line
Parameter fireRatingParam = wallFamilyInstance.Symbol.get_Parameter("Shared Parameter Name");

//Assuming this parameter is an integer. If it's not, use the appropriate type function
int value = fireRatingParam.AsInteger();

}

Hi Nitin,

The fire rating parameter of wall type is a built-in parameter.

So you can get the parameter value in the way of getting built-in parameter member.

Here is the code snippet to show the process.

<code>

[TransactionAttribute(Autodesk.Revit.Attributes.TransactionMode.Manual)]
public class RevitCommand1 : IExternalCommand
{
public Result Execute(ExternalCommandData commandData, ref string messages, ElementSet elements)
{

UIApplication app = commandData.Application;
Document doc = app.ActiveUIDocument.Document;

Selection sel = app.ActiveUIDocument.Selection;
Reference ref1 = sel.PickObject(ObjectType.Element, "Please pick a wall to get its fire rating");
Wall wall = doc.GetElement(ref1) as Wall;
if (wall == null)
return Result.Failed;

Parameter param = wall.WallType.get_Parameter(BuiltInParameter.DOOR_FIRE_RATING);

//show the fire rating in task dialog
TaskDialog.Show("Wall type fire rating", param.AsString());

return Result.Succeeded;
}
}
