In SOLIDWORKS 2012 (specifically SP1.0) you may have seen a new add in appear in the list (Tools > Add Ins). The SOLIDWORKS Part Reviewer is designed to help you understand the methodology adopted for a SOLIDWORKS Part. The Reviewer allows you to "step through" the model's history and using the comments function, you can add descriptive text at each step which is great when collaborating with suppliers, customers and even internally with your colleagues.
As well as the SOLIDWORKS Help Topics, and the SOLIDWORKS Forum we have a couple of useful videos uploaded on our Solid Solutions TV website. Check them out using the links below:
