Sometimes you change your mind about what goes where on your character, add a weapon after an arm, or legs after trousers. This can cause the characters body parts to be drawn on the screen in the wrong order: in CC3, things added later are drawn last on the screen. You can use CC3’s re-ordering icons to deal with problems like this.
Note: You may have to use the Redraw icon 
to see the effects of your reordering.
In this example, you have forgotten to place the Arm symbol before adding the Sleeve. You could erase the sleeve, add the arm, then add the sleeve again, but it is easier to place the arm, select the BACK icon 
, right click, select by Prior, right click, Do it.
In this example, you are adding a weapon to an already-drawn character. You can’t send the weapon to the back of the drawing, it would end up behind everything and invisible. In this case, after you have selected the weapon, select the JUST BEHIND icon 
, click on the edge of the hand, the select the weapon, Do it.
In this example you are adding a pouch to a symbol that already has a belt. Place the symbol, select the JUST IN FRONT OF... icon
, select the belt, the select the puch. Do it. The pouch is moved just above the belt, which is behind the weapon and left arm.
