Applying Chamfers

Use the Chamfer command to connect two Lines with a beveled corner. The selected entities do not have to intersect and they can overlap. If the entities overlap, they are trimmed to create the beveled corner.

You can specify a chamfer distance from the corner of adjacent Lines of both entities for nonsymmetrical chamfers. You can also define the connecting Line using a length and an angle.

Use Chamfer in plan view because chamfering operates on selection points and end points of entities.

  If you chamfer two Lines and both Lines are on the same Layer, the command places the chamfer Line on that Layer. If the Layers of the Lines differ, the command places the chamfer Line on the current Layer.

To apply chamfers:

  1. Click Modify > Chamfer (or type Chamfer).
  2. In the graphics area, select the first Line or specify an option:
    • Angle. Sets a chamfer length on the Line you first select and an angle for the second Line to create a chamfer Line.
    • Distance. Sets the chamfer distances. The default value for the first chamfer distance is the most recently used distance. The default value for the second distance is the value specified for the first chamfer distance. If you specify zero for both chamfer distances, the two Lines extend until they meet, if possible. In this way, the command implements an intersection and does not draw a chamfer Line.
    • Method. Indicates whether to use two distances (specified by the Distance option) or a length and an angle (specified by the Angle option) as the default for creating the chamfer.
    • Multiple. Lets you apply chamfers to multiple entities. By default, you complete a single chamfer. You are prompted repeatedly to select a first and a second entity to chamfer until you press Enter to complete the command. You can then change the chamfer distances or toggle the trim mode between chamfer operations.
    • Polyline. Lets you chamfer PolyLines treated as a single entity. The command chamfers all vertices of a PolyLine or polygon in one step and inserts chamfers at each vertex of the PolyLine where two Lines meet, if applicable. The Polyline option prompts for a 2D PolyLine, then reports the number of Lines processed and the number of Lines too short to be chamfered. The generated chamfer segments become part of the PolyLine.
    • Trim mode. Indicates whether to erase the Line segments that lie beyond the chamfer.
    • Undo. Reverses the previous chamfer, only if Multiple mode is active.
  3. Select the second Line.

    You can instead apply an acute corner by pressing Shift and specifying the second drawing entity. This method creates acute corners without changing the chamfer distances to join two end points.
