Posted on December 5, 2013 by Mark Lancaster, Synergis Product Support Specialist:
A while back I had a request to create a dimension to an applied intersection on an Inventor drawing.  Normally this is not something that is done frequently, so I wanted to share the steps to remind everyone how this is accomplished.
I have a round part that has a revolved groove in it and I need to dimension the overall width as shown.

However in my part, the sharp corners of the groove have been replaced with rounded edges and the detail view looks something like this.

Let’s start out by creating the extension line at the first applied intersection.

Step #1:       Start the dimension command and select one of the lines that would form the applied intersection.

Step #2:       Move the mouse in order to start previewing the dimension you are trying to create.  Right mouse click and select Intersection.

Step #3:       Hover over the other line that will form the applied intersection of the extension line.  When you do, a preview of the applied intersection will appear.

Step #4:       Left mouse click to define the starting point of the (first) extension line.
Step #5:       Repeat steps 1 through 4 on the other side of the groove.
Step #6:       Place dimension where required.
