Open, view, and mark up all 3D and 2D CAD data from within one, easy to use file? Sure. You'd expect nothing less from the market leader in digital design communications. But Spinfire Professional goes further, accurately preserving the part data as it is published in the software's .3D format. So, even without the original CAD data, you can compute volume and surface area, measure thickness and angles, and more. And any one can open and view all data and all mak-ups using Actify's free, downloadable Spinfire Reader.
