123D Make allows us the generate slices of the 3d Object. You can either use the desktop version or the online version. I will be using the online version.
Open 123D Make online http://apps.123dapp.com/make/
and login to view the My Corner items.
Drag-drop the model you created using 123D Catch. This should load the sliced version of the object.
Try messing around with the object size and orientation till you get good results.
