I come here, because I have a little question about shapes. i'll try to explain as much as I can, moreover I'm not an english native, so try to don't mind my grammar

- Is there any trick for a shape to be above and on top of another shape ? I always use up/down level or shape-cloning then menu object->cutting->set.
But maybe there is a cleaner / better / faster method exist ?

This is the style I try to make :
legend:
left one : light gray shape is an identical clone, and the dark grey is inside, using "menu object->cutting->set" method )
right one : the blue shape is in reality two shapes : but I wonder if it's possible to be only one ?

Here is a real case of the right example :
The tail goes on the upper and below the right leg on the same time.

As you can see, the tail is separated in two shapes, moreover I MUST use a little white shape to mask the part of the tail who goes upper of the left lef.
Disadvantages :
- if the left leg need to be modified, we must modify the little white masking shape too + it need to be on the same position of the leg
- in my opinion, it's easier to draw a curved shape when this shape is a single one.

Here is a real case of the left example :

I must draw the dress with the curve sleeve and the sleeve shadow apart
A better method would be :
Drawing the dress, make a identical clone of it, draw the sleeve shadow, select both clone and sleeve shadow then use menu "object->cutting->set".
But if we do this method, the arm can't be inside the sleeve, but only on top, or above of dress+sleeve shadow.
It's like the left example, a shape can't be on above the cut shape and on top of the clone shape at the same time. It's only on top or above the whole.
