What is Inventor Tolerance Analysis? 
Inventor Tolerance is a CAD-embedded tolerance analysis solution for assemblies. It’s a one-dimensional tool that reports out on the fit and tolerance of assemblies from Inventor. Stack-ups is able to automatically capture the relationships in an assembly model. If you’re an Inventor user that works more with Model-Based definition, you’re even able to change the tolerance values directly in the software.

What are the benefits of using it?
As a useful tool, Inventor Tolerance Analysis ranks up there in the design and manufacturing process, but you shouldn’t take my word for it. You can likely already access your own design practice and determine how this tool might fit into your workflows.
If you ever work on a product that has more than two components, then tolerances likely matter to you in some degree. Tolerances on the manufacturing floor can mean everything to your design’s success. It’s this key risk in the design to the manufacturing process that Inventor Tolerance Analysis aims to circumvent.
Being able to see the actual tolerance stack-up of an assembly before that product hits final approval is crucial – and Inventor Tolerance Analysis is more accurate than any handmade excel spreadsheet. Oh, and it also boasts an in-canvas workflow, so you don’t have to switch between programs.
At the end of the day, Inventor Tolerance Analysis is a based-in-reality practical tool for the everyday mechanical designer. It can and will help you save on costs by reducing manufacturing issues, minimizing warranty issues, and ultimately get you through the design process faster than ever before.

What’s next?
As engineers, we’re constantly seeking the next little thing that can optimize our workflows and our designs even further. I’d pose, that if you’re not using Inventor Tolerance Analysis, it might be the next optimization you were looking for…
