Delete Blended Faces Example (C#)

This example shows how to delete blended faces.

 

NOTE:  You can only delete blended faces from a temporary body.

//----------------------------------------

// Preconditions:

// (1) Part is open.

// (2) Part only contains one solid body.

// (3) At least one blended (filleted) face on the part is selected.

//

// Postconditions:

// (1) New part is created.

// (2) New part has same body as original part

//     but with the selected blended faces removed.

//

// NOTE: It might not be possible to remove the

// selected blended faces. If they're not removed, then

// the new body will be the same as the original

// body.
