 Description
-    Extrude mesh from existing patch or from patch read from file.
+    Extrude mesh from existing patch (flipped so has inwards pointing
+    normals) or from patch read from file.
     Note: Merges close points so be careful.
 
     Type of extrusion prescribed by run-time selectable model.
