Trim Multiple

“

- Trim Multiple allows you to extend or trim one element or multiple elements simultaneously, to their intersection with one or more elements in multiple directions. When trimming, you need to select the parts that will be deleted. You can find the tool on the Home tab in the Modify group. In this lesson you will learn: Trim Multiple. Open learning.dgn from the MSBasics\dgn\08-Modifying Elements folder. Open the Trim Multiple Model. The objects in the left column, show the desired results. In this first exercise, we'll be trying out the trim method. Zoom into the orange and blue elements, select trim, and select the trim method. First, select a circle on the right as the cutting element. Drag a selection line across the lines within the circle to identify the elements to trim. Note that this tool is different than trim to element in that you must select the parts of the element to be deleted. Reset to complete. Next, we'll try out the trim and extend method. Zoom into the white and green elements. Select trim multiple and the trim and extend method. With trim method, you can select multiple cutting elements, whereas with trim tool element, you can only select one element. Select the vertical line on the left as a cutting element, then press the control key and select the arc. These highlight as your cutting elements. Drag a selection line across the elements between both cutting elements to delete the parts of the elements between the line in the arc. Just like in the example on the left. Reset to complete. To demonstrate the extend feature in the trim and extend, draw an oblique line to the right of the arc. Continue with the trim multiple and the trim and extend method. Select the oblique line as the cutting element, drag a selection line across the lines between the arc and the oblique line, to identify the elements to extend. Reset to complete, delete the oblique line. Copy the vertical line to the right. We will extend the upper green lines, and the lower green lines. Continue with the trim multiple and the trim and extend method. Select the copied line as a cutting element. Drag a selection line across the lines between the arc, and the copied line to identify the elements to trim and to extend. Result is not what you wanted, because the wrong parts of the lower green lines are deleted. Undo the change. Select the copied line as the cutting element. First, drag a selection line between the arc and the copied line, to identify the elements to extend which in this case are the upper green lines. Then drag a selection line at the right of the copied line to identify the elements to trim. If needed, select the smallest parts to trim individually. Reset to complete. Hint, in the last exercise it's easier to use the trim to element tool instead, because it allows you to select all elements to modify on the left side of the cutting line. In this lesson, you learned Trim Multiple.
