Use the Modify>Chamfer options to chamfer line entities with or without trimming.

When adding chamfers, it will be important to keep the following in mind:

• In 3D construction mode, the program will attempt to create a plane from the selected entities. If both selected entities are lines, polylines, or vectors, then the program will always be able to create a plane. This plane will be at the depth of the first entity selected if the entities are at different depths with respect to this plane.

• If a plane cannot be created, or if the program is in 2D construction mode, the arc will be created using the active CPlane.

• Only line entities can be chamfered.
