In fact it is not too important. Unless you are using your own printer. Commercial 3D printers like Sculpteo of France will arrange your models in their printers in the most economical way (Batch Printing) with the proper texture. Only when you uploaded your model to the Commercial Printer's website you might see the model kind of laying down if you used Y up. Some 3D commercial printers will correct the visual orientation automatically. Most of their websites allow you to change the orientation to the way you wanted. That is only visually. &nbsp;If you are using &nbsp;3D printing as a form of rapid&nbsp;prototyping for Injection Mold Designing, then you should continue to use "Y" up. I think using the "Move"&nbsp;command&nbsp;to rotate your model in the work space is a good move. If you are just doing 3D printing you should set you default format to "Z" up in preference. &nbsp;</P> Wed, 27 May 2015 12:31:57 GMT Anonymous 2015-05-27T12:31:57Z
