Equations Functions in Solidworks

SolidWorks tutorial: How to utilise Equations functions in SolidWorks to speed up your Design process.
Using Global Variables and equations will allow you to automate the dimensions on your model and allow for quicker redesign process. This is particularly useful when the model has to be re-sized with a constant ratio, the model has dimensions that is related to each other, or different configurations are to be created within the file at a constant ratio. This function can also be used to keep track of the dimensions and modified without finding the face or features to edit by labelling each dimension and comment.
