Inventor Professional 2015
This extremely comprehensive version of Inventor enables you to quickly and effectively create models for your 3D mechanical engineering designs. More than one million standard components have been incorporated into the 2015 version, allowing your drawing to successfully develop into a fully-fledged 3D mechanical design with a dynamic simulation.
What's great about Inventor is that the focus is on how the design works, rather than on the modelling process. You can easily draw using several centrelines and change your drawing to a frame, linkage or other structure in an instant.
When you purchase a licence for Autodesk Inventor Professional 2018, you also have the right to use the 2015 version. This is the only way, in the new licensing structure, to "buy" Inventor Professional 2015 (further information on licensing).
