Learning Objectives
After Af completing this chapter, you will u be able to:
✓ ✓ Use U the se t h e FILLET FILLE T command c o mm a nd to to d dr aw w w w fill fi ll t ets, ro ds, und a d nd other h radii. dii
✓ Place chamfers and angled corners r with the CHAMFER command.
✓ ✓ Form F o rm a s a s pline plin e using u s in the g t h e BLEND BLEND command. c o o mm a nd
✓ Separate objects using the BREAK command and combine m 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 j obj ects f using g the SCALE command.
✓ Use the EXPLODE command.
AutoCAD includes many editing n n 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 first using the crosshairs, then
access the editing command, and finally complete the operation.
Using the FILLET Command Using the FILLET Co mmand
Design and drafting terminology refers to a rounded interior corner as a fillet, fi t
and a rounded exterior corner as a round. AutoCAD refers to all rounded corners as
fillets. The FILLET command draws a rounded corner between intersecting or nonin-
tersecting lines, circles, arcs, polylines, and splines. See Figure 11-1.
Setting the Fillet Ra adius
Access the FILLET command and then use the Radius option to specify the fillet
The radius determines the size of a f fillet and must be set before you select
AutoCAD stores the radius as the new default radius, allowing you to place
fillets of the f same size.. After you define the radius, select the first object and
hover the pick box over the second object to display a preview of the f operation.
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.
