This operation retrieves all non-block solids and non-quadrangular faces from the selected shape.
-A non-block solid is a solid that does not have 6 faces, or has 6 faces, but some of them are not quadrangular.
+A block solid is a solid that has 6 faces and 12 edges.
+
+A quadrangular face is a face that has 1 wire with 4 edges. If there are
+more than 4 edges in a single wire and C1 continuity mode is switched on,
+a face is quadrangular if it has 4 bounds of C1 continuity.
+
+All solids and faces from a shape that do not satisfy these conditions are
+returned by this operation.
