eXtrudy is an assistant to create things with 2D characteristics in a 3d world. This applies mostly to jewellery, coins, medals etc.. The tool is not able to create real free form 3d objects, but the results should be always printable. Thus it is some kind of 2.5D tool - but for a very special purpose and not for design in general (like professional software as zbrush etc.)

1. Before the last stage the corrdinate system works mostly in pixels. The tool is not meant to allow precise constructions or measurements. Only the last stage should help you to set the volume and bounding box straight. If you need exact scaling, you might post-process the object in another tool like netfabb, meshlab or blender.

2. the metric system rules ;-) - no seriously - at the moment I don't have time for that.
3. You could create a duck-like object with a simple silhouette a a very curved surface profile - maybe add an eye as decoration element. But with the 2.5D you could not model a free from like the mouth or a neck - see the pictures

4. maybe later - can't promise...

1. Where do you define the measurement system. I see that at the end of the process, you can scale in millimetres, but what is the measurement system used in the earlier stages such as when setting depths within the boundaries of the object? (Adding Decoration section)

2. Are our American friends required to use the metric system when the stl file is generated, or can the file be generated in the Imperial system?

3. How would you use this software to create an object such as a rubber duckie like this?

4. Would you add narration to Tutorial 7, please?
