== Generating Complex Surfaces ==
Besides [[EM.Cube|EM.CUBE]]'s standard planar objects, i.e. rectangle strip, circle strip, radial strip, ellipse strip, triangle strip, taper strip, regular polygon, spiral strip, polystrip and NURBS strip, you can use '''Surface Generator''' [[File:surf_gen_tool_tn.png]] to create a large variety of other [[Surface Objects|surface objects]]. Practically, any imaginable planar or non-planar surface can be synthesized in [[EM.Cube|EM.CUBE]]. These include:

A mathematical surface defined by z = sin(2*x)*exp(-y/2): (left) polymesh version, (right) smooth generic surface version.
# As in the previous case, you can choose between the two '''Polymesh''' or '''Generic Surface''' options. You can also preview the curve before finalizing its creation.
