Drawing Problems - Chapter 1 Features of the textbook iv AutoCAD and Its Applications—Basics Copyright Goodheart-Willcox Co., Inc. 305 Copyright Goodheart-Willcox Co., Inc.. 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 Radius Access the FILLET comman nd an nd then use the Radius option to specify the fi llet radius.. The radius determiness the size of a fi llet and must be set before you select objects.. AutoCAD stores the radius as the new default, allowing you to place addi- tional fi lletss 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.

Compisring aused Drthewingbetween a s Comp a ring Dr a wing s The COMPARE command to evaluate differences two drawing fi les. The fi les selected for comparison are overlaid in a newly created comparison drawing that displays the similarities and differences between the drawings. Use the COMPARE command when it is necessary to observe and document the differences between two drawings, such as when you are working on a design project and other members of the project team make changes to the design. Access the COMPARE command to display the DWG Compare dialog box. See Fto igure 15-26 . To activate the COMPARE command when no drawing is open, select DWG Compare in the Application Menu. Use the DWG 1 area to specify the fi rst drawing compare, designated DWG 1. If a fi le is open, current, and has been saved, it is listed as DWG 1. To select a different fi le, use the recent fi les drop-down menu or pick the ellipsis (… ) button and select a fi le in the Select a drawing to compare dialog box . Next, use the DWG 2 area to specify the second drawing to compare, designated DWG 2. In the comparison drawing that is created, any objects that are unique to DWG 1 are dark green (color 82) by default. Any objects that are unique to DWG 2 are red (color 1). To select different colors, pick the DWG 1 and DWG 2 color swatches to open the Select Color dialog box and select the desired colors. Once you specify the drawings to compare, pick the Compare button to create the comparison drawing and display the Compare contextual ribbon tab. See F igure 15-27. NOTE NOTE The general intent of the COMPARE command is to help evaluate a design before and after changes have been made. Therefore, DWG 1 and DWG 2 are typically separate fi les with unique names. AutoCAD alerts you if you select the same drawing fi le for DWG 1 and DWG 2. AutoCAD starts a new drawing fi le named Compare_DWG 1 vs DWG 2 where DWG 1 and DWG 2 represent the two fi le names. You can change the default name when you save the fi le. In F igure 15-27 , a residential fl oor plan saved by one drafter, named A-02-MMM , is compared to the same fl oor plan modifi ed by a second drafter, named A-02-DPM . AutoCAD names the new comparison drawing Compare_A-02-MMM vs A-02-DPM . In the new drawing, DWG 1 and DWG 2 objects are combined into single block objects. Blocks are explained later in this textbook. The comparison drawing contains layers from both drawings. Layer names are followed by _DWG1 or _DWG2 to distinguish the layers in each drawing.
