when i add an existing bearing, 6013 2RS1 from SKF for example, to a part of the body of my design, i need to draw first the space where the bearing will be helt... (100mm ext, 65mm int) - but it would be awesome to decide on your design where that bearing component would come and that i could (like extrude) push and pull the component to the right position in the body and that fusion builds the space around the bearing itself
another example : i use an existing bolt from a particular brand - it would be awesome when i present the bolt to the design, that fusion360 draws itself the hole and the exact threat and sinking for that particular bolt
