Benson Shaw Posted July 20, 2011 Share Posted July 20, 2011 Solid subtraction is fine. Another way is to extrude the shape. Draw a cross section of the tunnel as a 2d polylne and extrude that. Lofts also work, esp for a tunnel with varying cross section. Draw each cross section as a NURBS curve or a 2d poly then convert it to NURBS. Arrange them in top view like ribs on a boat hull. Then simple loft along the ribs. -B Quote Link to comment
