Creates a named Class Filter in Named Object Libraries, replacing any existing Filter with the same name.
The item class names in the formula$ argument, which reflect the Cadcorp SIS C++ class names, are not necessarily the same as those that appear in the SIS user interface, which are translatable. In particular the "Polygon" and "TopoLineString" item classes should be specified as "SeedArea" and "SeedChain" respectively. The class name to use in this method is stored in the Class name item property. The translatable class name is stored in the Item class property.
Available: GEO MD MM ME OD OM SISpy
This example creates a filter for all items excluding polygons:
sis.CreateClassTreeFilter ("NotPolygons", "+Item -SeedArea")
Note: Add a colon to the end of the class whose children you want to ignore, for example:
sis.CreateClassTreeFilter ("NotPolygons", "+Item -SeedArea:")
