"""Clear and easy to follow guide to (probably) some of the more commonly used tools and commands within this extensive software package written in plain English. Many exercises also assist the learner through the processes. Constraints and Loft function just a couple of the areas covered to a decent level. Ideal as a robust paperback document, as can refer to this whilst still having Inventor on screen. Am currently self-teaching myself all the traits of Inventor 2020, using it as part of a wider suite of software associated with 3D printing, so expect this to be well thumbed before long. Works well alongside the various courses available via Linked-In Learning."" - MickFareham "
