CHAMFER

A chamfer is an angle (usually 45°) formed at a corner. The following steps will use the CHAMFER command to make the beveled corners of the conference table and credenza.

• Step 18. Use the CHAMFER command to bevel the corners of the table (Figure 3-7), as described next:

  Prompt	Response
  Type a command:	Chamfer (or type CHA <Enter>)
  (TRIM mode) Current chamfer Dist1 = 0′-0″ Dist2 = 0′-0″
  Select first line or [Undo Polyline Distance Angle Trim mEthod Multiple]:	Type D <Enter>
  Specify first chamfer distance <0′-0″>:	Type 2 <Enter>
  Specify second chamfer distance <0′-2″>:	<Enter>
  Select first line or [Undo Polyline Distance Angle Trim mEthod Multiple]:	P1→ (Figure 3-7)
  Select second line or Shift-select to apply corner or [Distance Angle mEthod]:	P2→
  Type a command:	<Enter> (repeat CHAMFER)
  (TRIM mode) Current chamfer Dist1 = 0′-2″, Dist2 = 0′-2″
  Select first line or [Undo Polyline Distance Angle Trim mEthod Multiple]:	P2→
  Select second line or Shift-select to apply corner:	P3→

  Note

  Type M <Enter> (for Multiple) at the Chamfer prompt so you do not have to repeat the CHAMFER command.

• Step 19. Chamfer the other corners of the table (Figure 3-7).

• Step 20. Zoom in on the credenza.

Polyline

Because you drew the credenza using one operation of the Polyline command and used the Close option to complete the credenza rectangle, it is treated as a single entity. The CHAMFER command Polyline option chamfers all corners of a continuous polyline with one click.

Undo

Undo allows you to undo the previous chamfer.

Angle

The Angle option of the CHAMFER command allows you to specify an angle and a distance to create a chamfer.

Trim

The Trim option of both the CHAMFER and FILLET commands allows you to specify that the part of the original line removed by the chamfer or fillet remains as it was. To do this, type T <Enter> at the Chamfer prompt and N <Enter> at the Trim/No trim <Trim>: prompt. Test this option on a corner of the drawing so you know how it works. Be sure to return it to the Trim option.

mEthod

The mEthod option of the CHAMFER command allows you to specify whether you want to use the Distance or the Angle method to specify how the chamfer is to be drawn. The default is the Distance method.

Multiple

Multiple allows you you to chamfer multiple corners without repeating the CHAMFER command.

• Step 21. Use chamfer distance 2″ to chamfer the corners of the credenza (Figure 3-7), as described next:

  Prompt	Response
  Type a command:	Chamfer
  (TRIM mode) Current chamfer Dist1 = 0′-2″, Dist2 = 0′-2″
  Select first line or [Undo Polyline Distance Angle Trim mEthod Multiple]:	Type P <Enter> (accept 2″ distances as previously set)
  Select 2D polyline or [Distance Angle mEthod]:	Click anyplace on the credenza
  Four lines were chamfered

  Tip

  If the last corner of the credenza does not chamfer, this is because the Close option of the Polyline command was not used to complete the polyline rectangle. Explode the credenza and use the CHAMFER command to complete the chamfered corner.

  Note

  While in the CHAMFER command, hold down the <Shift> key to select any two lines that do not meet, and you can make 90° corners of those two lines. This is the same as a 0 chamfer distance but will work regardless of the chamfer distance set.

  When setting the chamfer distance, you can set a different distance for the first and second chamfers. The first distance applies to the first line clicked, and the second distance applies to the second line clicked. You can also set the distance by clicking two points on the drawing.

  You can set a chamfer distance of zero and use it to remove the chamfered corners from the table. Using a distance of zero will make 90° corners on the table. Then you can erase the old chamfer lines. This will change the table but not the credenza because it does not work with a polyline. If you have two lines that do not meet to form an exact corner or that overlap, use the CHAMFER command with 0 distance to form an exact corner. The CHAMFER command will chamfer two lines that do not intersect. It automatically extends the two lines until they intersect, trims the two lines according to the distance entered, and connects the two trimmed ends with the chamfer line.

  Note

  Remember to turn SNAP off and on as needed. Turn SNAP off when it interferes with selecting an entity. Turn it back on as needed.

• Step 22. Zoom in on a portion of the grid outside the conference room walls.

• Step 23. Draw a rectangle 26″ wide by 28″ deep using the POLYLINE command (Figure 3-8). Be sure to have SNAP on when you draw the rectangle. Next, you will edit this rectangle using the FILLET command to create the shape of a chair.
