I quickly modeled up a vase in Rhino using a cone, a ball and some boolean comands.
Using one simple spotlight I created a rendered image of my designn.
Then I used the section comand in Rhino to make 5 sections through my vase. These sections will be the 5 pices I laser cut to make a model of my vase.
The create surface tool allowed me to trace these sections to make a 3d image of what my laser cut vase would look like once printed and put together.
Using the line and trim commands I designed the joints that would allow all the pieces to fit together.
I then exported the wire frame into cad, seperated and rotated the pieces and cleaned them up. This file was pfd'd and sent to the laser cutter to create my pieces.
