I HAVE MADE THE SKETCH IN BOTH PART MODE AND IN MY ASSY!!?? BOTH ARE SET TO SHOW IN THE FEATURE TREE AND STILL NOTHING. THE ONLY THING I NOTICED THO IS BY THE GLASSES AT THE TOP OF THE DRAWING SPACE EVERYTHIG IS GREYED OUT SO I CANT GLOBALLY SET SKETCHES TO "SHOW" SO THAT MAY BE WHY, THE ONLY THING I CAN CLICK IS THE "DECALS" BUTTON?? BUT IDK HOW TO GET ALL OF THOSE TO BE CLICKABLE AGAIN. NEED SOME HELP PLEASE AND THANK YOU
