Use the Trim and Extend tools to trim or extend one or more elements to a boundary defined by the same element type. You can also extend non-parallel elements to form a corner, or trim them to form a corner if they intersect. When you select an element to be trimmed, the cursor position indicates the part of the element to retain.
You can use these tools with walls, lines, beams, or braces.
