v1.3 [Jun 8, 2013]
What's new in version 1.3
• Access the new Autodesk 3D Print Utility from the "3D Print" menu to optimize your model for 3D printing. Hollow the model to save print time and material, position the model to minimize the support material, see a preview of the support material, and use adaptive thickening to adjust details that are otherwise too small to print.
• Create 2D layouts. This new feature is available to 123D Premium members. Export a .dwg file containing several 2D views of your project which you can open in AutoCAD WS or other apps.
• Go Premium. You can now buy 123D Premium Membership as an in-app purchase.
• UI improvements and bug fixes.
