In future versions of Shapes3D there is one change that will significantly alter its behaviour but will only affect existing sketches that have created composite shapes through the use of the method
Code:

addShape(aShape); 

The composite shape feature can be seen in the Earth/Moon example that comes with the library. Where there are 2 Ellipsoids earthand moon; a composite shape was created with
Code:

 earth.addShape(moon); 

In this example the earth object is the parent and the moon object the child.

In versions up to and including 1.7.0 when the parent is made invisible the children are unaffected so
Code:

earth.visible(false); 

would hide the earth but leave the moon visible.

There were good reasons for doing this at the time, but later versions provided features that made this unnecessary, so in the next version if a parent is made invisible then the children will not be displayed which is a more logical behaviour.

If this affects your sketch and you are not sure how to overcome it then let me know.
