If you want to select an intersection, but don't have two lines that meet, what do you do? Many times while training customers, I have noticed hesitation when this comes up. Users will often extend lines so they meet, or try to finagle some other osnap into doing what they want. But, there is an easier way!
In the example below, I want to select the lower right corner as the first point of a Bayspace. Since the two steel structural members don't instesect, I can't pick them outright to get the intersection. But, I can still use the INTersection osnap.
Starting the Bayspace command (or any command you want), pick the INT osnap and then pick one of the pieces of steel. Notice that the tooltip actually says Extended Intersection and it is followed by an ellipsis (…), indicating that it is waiting for more input.
After you pick the first piece, notice that the command line says 'and'. It is waiting for you to select another item from which it can build an intersection.
Now, hover over the second piece, near the imagined intersection. You will see the Intersection tooltip and glyph. Select it. You've got your intersection!
