Hi Jeremy and everyone,
First of all, I would like to thanks Jeremy Tammik, who create Revit Lookup so I can easily find all information of an element.
When I debug a view schedule, its DefinitionId.CategoryId has a value (-2008044), but when I lookup in revit, DefinitionId.CategoryId is null.
Why in this case it's null? Because I want to lookup which category this view schedule belong to.
Shai.
Thank you for your appreciation. Glad you like it.
A negative category id refers to a built-in category.
Look at the BuiltInCategory enumeration values in the debugger and you will see:
Hi:
I looked up the API help document.
Enum integer value -2008044 is 'OST_PipeCurves'.
This element should be a Pipe or FlexPipe.
public static BuiltInCategory GetBuiltInCategory(this Element elem)
{
Category category = elem.Category;
if (category == null) return BuiltInCategory.INVALID;
return (BuiltInCategory)category.Id.IntegerValue;
}
Very wierd, I'm not familiar with ViewSchedule.
I'm not quite sure but I expect its value like this instead of null
Otherwise is there any other way to find category which view schedule is belong to by Revit Lookup?
