Motivation

Extrusion is currently limited to only along a single direction. To create items such as pipe bends, an extrusion needs to take place along a 1D curve. This will aid in applications for the Navier-Stokes module.

Design

Feature should take a 1D meshed curve that is fixed to a face or side and extrude the mesh along.

Impact

Will allow users to easily create meshed curves and bends in their geometry without using an external mesher like Cubit.
