Get and Fill Gaps in Body Example (C#)

This example shows how to get and fill the gaps in a body.

//---------------------------------------------------------------
// Preconditions:
// 1. Open a model document that contains at least one body
//    with one or more gaps.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Identifies the number of gaps in each
//    body and fills each gap with a fill-surface
//    feature.
// 2. Examine the Immediate window and the FeatureManager
//    design tree.
