Function Description

In the Gallery control in the Object Editing group on the Object Operation tab, a function to generate a chamfer is provided. Chamfers and rounds are similar in that they join two objects. Rounds meet in smooth arcs, while chamfers meet in straight angles.

Extend or trim the adjacent ends of two line segments, eventually joining them to form a chamfer. As shown in the following figure, when both chamfer distances are 0, the two lines are trimmed or extended until they intersect. When both chamfer distances are not 0, the two line segments are extended by the specified distance, and then the two lines are connected.

• The Bevel button is available only when two line segments are selected in an editable layer, that is, the function is only available for the two selected line segments.
• The object participating in the generation of the chamfer must be a simple line object with one and only one intersection point for its extension lines. If the two lines are parallel to each other or on the same line, the operation is not successful.
• When the operation is complete, the source line may be extended, trimmed, and the Attributes may not change.
• Chamfer Distance Parameter Description: When generating a chamfer, there are strict restrictions on the two distance parameters. The range of the distance parameter is the distance from the intersection of the two lines to the farthest endpoint. Application gives an error for parameters that exceed this length.
• Although the cross line can be chamfered, there is no obvious scientific significance, so this situation is not described in detail.

Function entrance

• Object Operation tab-> Object Editing group drop-down box-> Bevel.

Operating instructions

1. Sets the Layer of Object of the segment to generate the chamfer to the Current Editable Layer.
2. Select two segment objects (non-parallel lines) in the layer at the same time.
3. In the Gallery control of the Object Editing group on the Object Operation tab, click the Chamfer button to bring up the Chamfer Settings dialog. Enter the distance to the first line and the second line in the pop-up dialog box. By default, the distance to the first line and the distance to the second line are both 0. In this case, the two lines are directly connected at the intersection.
4. Set whether to Trim Source Object. Check this box to indicate that the source object will be trimmed after the operation, otherwise the original object will be retained.
5. The preview effect of the generated inverted right angle is displayed in Map in real time. Click the OK button to execute the operation of generating the chamfer according to the user's setting.

Parameter Description

First line chamfer distance: The distance from the intersection of the extension lines of the two lines to the nearest endpoint of the first line after the first line is trimmed or extended. As shown in the right figure below, the chamfer distance of the first line is 100.

Second Line Chamfer Distance: The distance from the intersection of the extension lines of the two lines to the nearest endpoint of the second line after the second line is trimmed or extended. As shown in the right figure below, the chamfer distance of the second line is 50.

• 1 represents the first line, 2 represents the second line, and 3 represents the newly generated chamfer line.
• The first line is trimmed and the second line is extended.

Caution:

• Distance Valid Range Description The minimum value of the

  distance is 0; the maximum value is the distance from the intersection of the two lines to their respective farthest endpoints. If the value is greater than this value, the Output Window will prompt that the input distance value is too large, and the inverted right angle fails.

  If the distance is 0, there will be some special changes in the chamfer line, as shown and described in the following table.

  The

  First line chamfer distance	Second Line Chamfer Distance	Illustration	Explain
  0	Non-zero		The first line is extended to the intersection of the two lines. The second straight line is trimmed. The newly generated chamfer line is located on the extension line of the first line in the result, and the length is the chamfer distance of the first line.
  Non-zero	0		The first straight line is trimmed. The second line is extended to the intersection of the two lines. The newly generated chamfer line is on the extension line of the second line in the result, and the length is the chamfer distance of the second line.
  0	0		first line and the second line are extended to the intersection of the two lines. The newly generated chamfer line is located at the intersection and is a false straight line with a length of 0.

• Direction description When the operation is

  completed, the direction of the source line will change, as shown in the following illustration and description.

  • 1 represents the first line, 2 represents the second line, and 3 represents the newly generated chamfer line.
  The direction of the
  • newly generated chamfer line is from the first straight line to the second straight line.
  The
  • first line changes direction to the opposite of the newly generated chamfer line.
  The direction of the
  • second line changes to be the same as the newly generated chamfer line.
