Hello
My addin is attempting to create a Pipe. I have run into a problem if the user's Revit Project type is Architectural, Construction or Structural.
If I run my Addin when the user has these kinds of projects open, then I cannot create a Pipe because there are no PipeTypes loaded into the project. See my code below that you can run in a Non-MEP Project and it will show no PipeTypes are loaded.
Is this normal? Do you know how I can create a Pipe when the user is in a Non-MEP Project?
Some relevant information:
- This error occurs in Revit 2013.
- Using Revit 2014, I can successfully create a Pipe in a Non-MEP Project. This is because there is 1 and only 1 PipeType loaded ("Default")
- I am using the Student Version of Revit 2013 and 2014 so this might mean that not all PipeTypes are loaded?
Run this code in your own version of Revit to replicate the error (No PipeTypes loaded in Non-MEP Projects):
[TransactionAttribute(TransactionMode.Manual)]
[RegenerationAttribute(RegenerationOption.Manual)]
public class Lab1PlaceGroup : IExternalCommand
{
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
UIApplication uiApp = commandData.Application;
Document doc = uiApp.ActiveUIDocument.Document;
Transaction trans = new Transaction(doc);
trans.Start("Test");
#region Determine Pipe Types available in this project
/*

PipeType pipeType = null;
FilteredElementCollector collector = new FilteredElementCollector(doc);

foreach (Element ptype in collector) {
TaskDialog.Show("Name: " + ptype.Name, "Notification");
if (string.Compare(ptype.Name, "standard", true) == 0) {
pipeType = ptype as PipeType;
break;

trans.Commit();
return Result.Succeeded;
}
