Ex ercise 8-7 www.g-wlearning.com/CAD/ Complete the exercise on the companion website. Filleting Solid Objects Filleting Solid Objects A fi llet is a rounded interior edge on an object. A round is a rounded exterior edge. See Figure 8-18. The FILLETEDGE command is used to create fi llets and rounds on 3D objects. Additionally, the FILLET command can be used to fi llet 3D objects. Before a fi llet or round is created at an intersection, the solid objects that intersect need to be joined using the UNION command. Then, use the FILLETEDGE command. See Figure 8-19. Since the object being fi lleted is actually a single solid and not two objects, only one edge is selected. In the following sequence, the fi llet radius is fi rst set at .25, then the fi llet is created. FILLETEDGE Ribbon Solid Solid Editing Fillet Edge Type FILLETEDGE A C B D Construction ellipse Select the center point of the top of the cylinder as the base point of the array Figure 8-17. Using the ARRAYPATH command to create the cylindrical feet and supports for an oval table. A—The bottom shelf is created as an extruded ellipse. A construction ellipse is created to serve as the path for the 3D path array. A construction cylinder is the object to be arrayed. B—A 3D path array consisting of two levels with four items on each level is created. The array is created as a non-associative array. C—The supports are edited to the correct diameter and height. D—The bottom shelf is copied along the Z axis to create the top. Shown is a shaded version of the completed model.
