Get Bounding Box Example (C#)
This example shows how to get the bounding boxes for the selected feature and
face. This example also shows how to draw 3D sketches depicting the bounding
boxes.
//----------------------------------------------
// Preconditions:
// 1. Model document to open exists.
// 2. Open the Immediate window.
// 3. Run the macro.
//
// Postconditions:
// 1. Selects Sweep1 feature.
// 2. Creates a 3D sketch of the bounding box of
// the selected Sweep1 feature.
// 3. Selects top face.
// 4. Creates a 3D sketch of the bounding box of the
// selected face.
// 5. Examine the graphics area and the Immediate
// window to verify.
//
// NOTE: Because this model document is used elsewhere,
// do not save changes when closing it.
