Solid Face>Shadow Taper
This local edit function provides draft to curved faces in a mold. It fills in gaps that are not visible from a specified direction. The purpose of this operation is to remove face regions with normals perpendicular to the draft direction. It introduces new ruled faces in order to remove regions from the nominated faces where the draft is thought of as being in shadow from a beam of light traveling with the draft direction and angle. It detects special geometry cases on spheres, cones, and Torii and makes a cone or plane for the taper surface rather than a spline.
Using the Function:
Below > The taper angle was 30 degrees. All five curved faces were selected at once for the operation by depressing the CTRL key and picking each face. The vector was used as the mold extraction vector.
Below > Both of the curved faces below were tapered using a 15 degree taper angle. The right vector was used for the mold extraction vector on the outside face. The left vector was used for the curved face nearer the center of the solid.
