Merge Arc Segment Bodies With Adjacent Bodies Example (C#)

This example shows how to create structural-member groups with and without merging arc segment bodies with adjacent bodies.

//--------------------------------------------------------
// Preconditions:
// 1. Verify that the specified files exist:
//    * part template
//    * weldment profile
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens a new part.
// 2. Creates a sketch of two lines and two tangent arcs.
// 3. Creates a structural-member group using an adjacent line and arc
//    and merges the arc segment's body with the line's body.
// 4. Creates another structural-member group using the other adjacent
//    line and arc and does not merge the arc segment's body with the
//    line's body.
// 5. Examine the Immediate window.
// 6. Expand Cut list(3) in the FeatureManager design tree.
// 7. Point at each PIPE, SCH 40, 12.70 DIA. and examine the 
//    graphics area to verify whether that PIPE, SCH 40, 12.70 
//    DIA. is merged.
