Remarks
Retrieves and set analytical model projection information for Z direction.
To set projection to level, grid or plane use ProjectionPlaneZ property.
Examples
Copy
C#
/// <summary>
/// Change the Z projection for all surface elements to BottomOrExterior
/// </summary>
public void ChangeSurfaceProjections(Document document)
{
FilteredElementCollector collector = new FilteredElementCollector(document);
IList<Element> elements = collector.WherePasses(new ElementClassFilter(typeof(AnalyticalModelSurface))).WhereElementIsNotElementType().ToElements();
if (elements.Count > 0)
{
using (Transaction tran = new Transaction(document, "Change Surface Projections"))
{
tran.Start();
foreach (AnalyticalModelSurface ams in elements)
{
SurfaceElementProjectionZ orgEndProj = ams.ProjectionZ;
SurfaceElementProjectionZ newEndProj = SurfaceElementProjectionZ.BottomOrExterior;
ams.ProjectionZ = newEndProj;
}
tran.Commit();
}
}
}
