Using existing geometry to set the current layer

Based on what we have seen so far, you may be thinking that we need to know a layer's …name in order to make it current. …This is not the case. …In this lesson, we'll learn a shortcut that allows us to set the current layer by picking …objects on screen. …In this example, I have an unfinished mechanical part consisting of a top and front view. …Take a look at these edges. …These would show up in the top view as a solid line. …In order to draw that geometry, I need to make sure the part layer is current. …At this point, I don't know what name is being used for the part layer, and you know what, …I don't have to know it.…

If I come up to the Layers panel, I can click the Make Object's Layer Current button, select …the layer I am interested in and that becomes the current layer. …I will then launch the Line command and I'll create a line from this endpoint. …I'll lock the Ortho and I'll drag this line out through the part. …I'll click and I'll press Escape when I am finished. …Then I'll create a copy of this line. …
