Understanding and applying equations in parts

When creating 3D models, we often use a variety of dimensions to define sketch entities such as squares and arcs. We also use dimensions to define features such as an extruded boss, an extruded cut, a revolved boss, and a revolved cut. In many applications, these dimensions are not isolated from each other. Rather, they are connected with mathematical relations. For example, the length of a rectangle should be 75% of its width or the highlight of a cylinder should be double the length of its diameter. In this part, we will learn how to set up these relations with equations. First, we will explain the equations, then we will apply equations in the modeling of a SOLIDWORKS part.
