Keep those macro names unique

If you try to create a macro named “Line” the result will be an error like:
‘ThisApplication.Line()’ is a ‘method’, which is not valid in the given context (CS0119)”

The red squiggly line indicating the error is misleading. The problem here is not really on line 38. The problem is that the name of your macro defines a method called Line which does not have a CreateBound method. Then the compiler gets confused when you try to call the CreateBound method on the Autodesk.Revit.DB.Line class.

So keep those macro names unique to avoid this problem. Renaming the macro to Line1, LineTest, or anything like that will solve the problem.

Finding those constraining dimensions

Steve asks a lot of good questions and it is nice that the API is often able to help answer them. Recently he asked “Where are the Constraining Dimensions?

Here’s how to use the Dimension.IsLocked property to find those constraining dimensions:

For the entries where a segment of a multi-segment dimension is locked (such as #s 30, 31, 32), every reference of every segment is listed instead of just listing the two references related to the locked segment. This happens because while the Dimension class does has a References property, the DimensionSegement class has no such property. So the output is all references of the “parent” dimension instead of the two references of the relevant segment.

public void getConstraints()
{
    Document doc = this.ActiveUIDocument.Document;
    string data = "";
    int ctr = 1;
    foreach (Dimension d in new FilteredElementCollector(doc)
             .OfClass(typeof(Dimension))
             .Cast<Dimension>())
    {                
        if (d.NumberOfSegments == 0 && d.IsLocked)
        {
            data += ctr + ": id = " + d.Id.IntegerValue + " " + getReferenceNames(doc, d.References) + Environment.NewLine;
            ctr++;
        }
        else if (d.NumberOfSegments > 1)
        {
            foreach (DimensionSegment ds in d.Segments)
            {
                if (ds.IsLocked)
