Drawing Problems - Chapter 1 Features of the textbook iv AutoCAD and Its Applications—Basics Copyright Goodheart-Willcox Co., Inc. 305 Copyright Goodheart-Willcox Co., Learning Objectives After completing this chapter, you will be able to: ✓ Use the FILLET command to draw fi llets, rounds, and other radii. ✓ Place chamfers and angled corners with the CHAMFER command. ✓ Form a spline using the BLEND command. ✓ Separate objects using the BREAK command and combine objects using the JOIN command. ✓ Use the TRIM and EXTEND commands to edit objects. ✓ Change objects using the STRETCH and LENGTHEN commands. ✓ Edit the size of objects using the SCALE command. ✓ Use the EXPLODE command. AutoCAD includes many editing commands and options to complete common drafting tasks, improve efficiency, and modify a drawing. This chapter explains methods of using basic editing commands to change existing objects by changing or adding geometry. The editing method used in this chapter is to access a command such as STRETCH and then follow the prompts to complete the operation. Another technique, presented in Chapter 13, is to select objects fi rst using the crosshairs, then access the editing command, and fi nally complete the operation. Using the FILLET Command Using the FILLET Co mmand Design and drafting terminology refers to a rounded interior corner as a fi llet and a rounded exterior corner as a round. AutoCAD refers to all rounded corners as fi llets. The FILLET command draws a rounded corner between intersecting or noninter- secting lines, arcs, circles, ellipses, polylines, splines, xlines, and rays. See Figure 11-1. Setting the Fillet Ra adiusus Access the FILLET comman nd an nd then use the Radius option to specify the fi llet radius.. The radius determines the size of a fi llet and must be set before you select objectts. AutoCAD stores the radius as the new default, allowing you to place addi- tional fi llets of the same size.. Once you define the radius, select the fi rst object and then fillet: A rounded interior corner used to relieve stress or ease the contour of inside corners. round: A rounded exterior corner used to remove sharp edges or ease the contour of exterior corners.
