■ Same Property Value - any items found clashing that share a specific property value are not reported in the
results. This template can be used when the information is stored on the same property.
■ Same Selection Sets - any items found clashing that are contained within the same Selection Set are not
reported in the results.
■ Specified Selection Sets - any items found clashing that are contained within two specified Selection Sets are
not reported in the results.
■ Specified Properties with the Same Value - any items found clashing that share the same value, but on two
different properties are not reported in the results. This is a new rule template. This rule also enables you to
look for the property on any parent object. For example, the gasket at the end of a pipe is registered as a clash
with the nozzle of pump. These items should be connected. The gasket itself does not have any property
attached directly to it to identify that it should be attached to the nozzle of the pump; however the parent
object of the gasket does. If you use this template, the clash test ignores clashes between these two items.
