Dynamic Trim panel
This function combines the most widely used wireframe editing tools into a single function with different modes. For each mode, you have the option of trimming or extending entities, or breaking single entities into multiple pieces.
Auto-preview displays the results of the selected function as you move the mouse over the final entity selection. As with other trim, break, and divide functions, a solid line represents what will be created. A dashed line represents what will be removed.
