Yup, now you see why they call it "rule #1." As MikeWi pointed out, the sketches are still there but the design becomes very confusing when you do it the way you did rather than create components before creating geometry.I drew several bodies and then converted them to components (not following rule #1.) Now that they are converted and are part of an assembly, I have lost any ability to see the timeline or the underlying sketches. Is this normal? Would this be different if I created the component first and then added the sketches?
