When using the draft tool selecting the face to draft the fixed edge should highlight in a colour, however because of the prehighlight of the selection it does not show unless a wireframe view is used (and only just even then) it would be good to have the fixed edge highlight on top see my examples below
Below is how inventor currently looks with shaded view

Below is how it looks using wireframe you can just makeout the purple line indicating the fixed edge

Below is a very rough idea of how i think it should look, this will make using the fixed edge draft tool much more straight forward and easier for new users
