Throws away the contents of a geometric primitive or a segment but leaves the structure intact.
key - Key returned by a previously called routine.
If key refers to a polyline, polygon, or shell, all the points (and all of the faces) within the primitive are removed. New points, if desired, can be added with Edit_Polyline() , Edit_Polygon() , or Edit_Shell_Faces() .
If key refers to text, all the characters are removed. New characters can be added with Edit_Text() or via user input with Enable_String_Events() .
Flush_By_Key() is a quick method of making sure all the contents of a piece of geometry are gone. The "Edit" routines take more work and only remove some of the contents.
Lastly, if key refers to a segment, this call becomes a call to Flush_Geometry() on the segment. If the key refers to a Style or an Include, nothing happens.
