I created an elevation view of a rolling mill. In Inventor 2011 I was able to click on this view and then 'Create a Sketch' and add a line that bwould represent the passline of the metal flowing thru the mill. I could then dimension from a line or surface of the mill to the sketched line. This would but the sketched line in the right position. We upgraded to Inventor 2013 last year and I tried this procedure the other day and could not get it to work. I can draw the line but cannot dimension it to the part in the view. Am i doing something wrong or did Autodesk eliminate being able to do this?
