Does has swift3D have anything like a NULL object I can use to house other models!

Hi, I’m relatively new to swift but am kinda excited by the vector output functions available, for export into flash for small file sizes.

I’m just wondering if there is anything like a “NULL” object like the ones Cinema4D and MAX seem to have to allow you the chance to operate on different levels of transfomation for different parts of a movement in 3D space. I know I can sort of bodge it and stick in a tiny sphere into my work, but would love to know if there is actually a REAL way to perform this kind of function.

TANKS!
