It took a bit of lateral thinking but after a time i realized one could build the most complex of shapes very quickly in beta 2.07 .
1- simply inflate a cross section of our model
2- then copy that object around in 3d space
3- do merges on those objects as required
complex sections can be made in minutes using this method
