Get Sketches Example (C++ COM)

If you use a sketch to create a feature on your solid body, that sketch is a subfeature of that solid feature. This is illustrated by expanding and examining the FeatureManager design tree of a SOLIDWORKS feature.

This example shows how to traverse the FeatureManager design tree and use subfeature traversal to grab the ISketch objects used by each feature.
