Origami + Mathematics + AutoCAD

These are some experimentations creating some origami figures, using curved folds with the aid of AutoCAD and mathematical functions... A very interesting work...In my opinion the most difficult part is to collapse the models because you need to consider the spatial placement of it, it means, you have to collapse the figure in all directions... I will be very glad for all your comments and sugestions to do better works... The models were folded with standard copy paper as a first approach...
