Ok, my brain is not working today. I want to create a block based MVPART. If I remember correctly I need to draw the unit, then create block and then convert to MVPART. I have done this before, It has been a while and I am just missing something this time. I am trying to make a condensing boiler. I make a box from the solids tab. I try to place a circle on the side plane of the box so i can extrude it to make the inlet and outlet for my piping. It will not allow me to do so. Can someone please tell me what I am forgetting?
