Remarks
The term "curve driven" indicates that the element's Location property is a LocationCurve.
Example elements found by this filter include walls, beams, and curve elements.
This filter is a quick filter.
Quick filters operate only on the ElementRecord, a low-memory class which has
a limited interface to read element properties. Elements which are rejected
by a quick filter will not be expanded in memory.
Examples
CopyC#// Create an ElementIsCurveDriven filter to find slanted columns(which is curve-driven) in the document, // The term "curve driven" indicates that the element's Location property is a LocationCurve ElementIsCurveDrivenFilter filter = new ElementIsCurveDrivenFilter(); // Apply the filter to the elements in the active document, // Use the ElementIsCurveDrivenFilter on columns to find only slanted columns (vertical columns // are placed at a single point). FilteredElementCollector collector = new FilteredElementCollector(document); ICollection<Element> slantColumns = collector .WherePasses(filter).OfCategory(BuiltInCategory.OST_StructuralColumns).ToElements(); // Find elements of not curve driven: use inverted filter to match elements ElementIsCurveDrivenFilter notCurveDrivenFilter = new ElementIsCurveDrivenFilter(true); // inverted filter collector = new FilteredElementCollector(document); ICollection<Element> notCurveDrivenFounds = collector.WherePasses(notCurveDrivenFilter).ToElements();
