Drawing Problems - Chapter 10 Copyright Goodheart-Willcox Co., Inc. Chapter 10 Advanced Surface Modeling 267 3. General Create the hair dryer handle shown. Create the base profile using a spline and a straight line segment. Use the profile to create a planar surface. Then, extrude the planar surface and fillet the bottom end. Finally, convert the model to a NURBS surface and edit the top surface. A. Draw a spline and a line to create a profile similar to the profile shown. Use the CV option of the SPLINE command to create a CV spline. Dimensions are not important. Create the general shape by picking points to define the control vertices as indicated. Draw a line to form the straight segment at the top of the handle. Then, use the JOIN command to join the line to the spline. The resulting object should be a single, closed spline. B. Create a planar surface from the profile. C. Extrude the planar surface to a height of .85 units. D. Use the SURFFILLET command to fillet the bottom end of the handle. Use a radius of .375 units. Set the trimming mode to Yes. E. Using the CONVTONURBS command, convert the model to a NURBS surface. Edit the control vertices of the top surface to create a different shape. F. Save the drawing as P10-3. Line A B Points picked for CV spline Resulting spline
