I see you seem to be moderating this board, so I'll direct this to you. I saw the example of the cube and hole you did elesware on here, and for the life of me I would have never had figured it out.
So here is a real world project I would like to try with Fusion. I have the attached frame and I need to add "pads" to the I-beams as per attached photo (I did in 2010) and change the through holes in each end into extruded pins which face in. I've fooled around all morning with no significant progress. Can you give me an idea of the workflow I might want to try?
