EDT 310 - Basic Editing Commands The EXTEND Command The command format is similar to TRIM. You are asked to select boundary edges, as opposed to cutting edges. Boundary edges are objects such as Lines Arcs Text to which the selected objects are extended. EDT 310 - Basic Editing Commands
EDT 310 - Basic Editing Commands The EXTEND Command You can also EXTEND an object to an implied intersection. Select the Edge option. When you enter the Edge option, the choices are Extend and No extend. EDT 310 - Basic Editing Commands
EDT 310 - Basic Editing Commands The EXTEND Command When Extend is active the boundary edge object is checked to see if it intersects when extended. If an intersection does exist, the implied intersection point can be used as the boundary for the object to be extended. EDT 310 - Basic Editing Commands
