Check if the dimension is to a reference plane inside a family document

[Anonymous]

How can I know if i collect all the dimensions in a family document, that their referenced to a reference plane or level?

You can check each reference in the dimension.References property.

A reference has a property ElementId, which you can use to get the referenced Element and determine if it's a Level or a Reference Plane.

Dimension dim;
foreach (Reference r in dim.References)
{
	Element e = doc.GetElement(r.ElementId);
	if ( e is ReferencePlane) 
	{
		TaskDialog.Show("result", "dimension has reference to Referenceplane "+ e.Name);
		break;
	}
}
