It has been very easy for us to use this product as it integrates with our CAD software so that we can easily build models in SolidWorks or AutoCAD and then export them as.cw files which are compatible with Onscale's products. This program also allows us to save time by not having to go through multiple steps to get our models converted from one file type to another. There really isn't anything I dislike about Onscale! They have always been helpful when ever needed. The only thing they could do better would be to give more training on how to best utilize their products. We were able to create complex parts quickly thanks to Onscale.
