Hi Andy I watched that. It did look a long winded. Near the end you seem to be repeatedly trying to dimension values that are already defined?
Also, to sketch a fillet, there should be two ways to do it. Either click on the two lines, as you did, or simply click on the vertex. It's a lot quicker. I presume inventor supports that?
