Curve elements are either open or closed elements that can describe a path.
The following standard types always represent a path:
These types support the ICurvePathQuery interface and can return linear properties such as length and answer other curve type queries. An EXTENDED_ELM can also represent a path by supporting the ICurvePathQuery interface. For this reason an application that wants to support any element that can describe a path should be written to dynamic_cast the element handler to the ICurvePathQuery interface instead of switching on element type.
