Drawing Problems - Chapter 13 Copyright Goodheart-Willcox Co., Inc. 340 AutoCAD and Its Applications—Advanced 4. Architectural Shown are the profiles of a roof gutter (for the collection of rain- water) and a gutter downspout. Draw the profiles in 3D using the dimensions shown. Use the following additional information to construct a 3D model like the one shown in the shaded view. A. Offset the gutter profile to create a material thickness of .025″. Be sure to close the ends to create a closed polyline so a 3D solid is created when it is extruded. B. Extrude the gutter profile 12″ to create a one-foot section. C. Relocate the downspout profile on the underside of the gutter. D. Construct an extrusion path for the downspout. Refer to the shaded view, but use your own design. E. Extrude the downspout profile along the path. F. Dimension the end of the gutter profile in 3D. G. Save the drawing as P13-4. 5. Mechanical Open P5-4. If you have not completed this problem, construct it using the directions for the problem in Chapter 5. Display the 3D view in a single viewport. Then, add dimensions to the 3D view. Plot the drawing on a C-size sheet of paper. Save the drawing as P13-5. Gutter Profile A B Downspout Profile
