How to handle complex 3d figure?

[lgsinmccalla]

I have been making various carvings using models available from Carrara. This is my most complex one. I have manually created slices (in Carrara) on a single axis and imported to designer. With a complex figure a single axis produces many layers to some parts (i.e. the wings in this figure). Will STL divide figure to allow different portions to be sliced on it's own axis? For example could each wing be sliced on a different axis.
