Get Areas of MidSurface Faces Example (C#)
This example shows how to get the areas of mid-surface faces.
//-----------------------------------------------------------
// Postconditions:
// 1. Verify that the part to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the part.
// 2. Selects two faces and inserts a midsurface feature.
// 3. Gets the number of faces in the midsurface feature.
// 4. Gets the areas of the faces in the midsurface feature.
// 5. Examine the Immediate window, FeatureManager design
// tree, and graphics area.
//
// NOTE: Because the part used elsewhere, do not save changes.
