I was following along with the video "buyers guide weldment" http://www.youtube.com/watch?v=GtqXUuNZKog
But ran into problems with over defining the sketch when defining the dimensions. I do notice in the video that I am getting different relations icons when drawing though.
As far as I can see I am copying the actions exactly, but I assume that when initially using the center rectangle tool that it's not creating the correct relations.
For example when drawing the verticle lines from each corner I can see in the video they get perpendicular icons where I get concentric circles?
