Many times you will be given a STL file and need to convert it to a prismatic body. If you have a Fusion 360 Personal license you find this is a particularly hard job since you do not have this option in the Convert Mesh tool. Even when you have this option, you often find the process does not give good results. In this video I walk you through the process of using the Mesh Section Sketch Tool, located in the Mesh environment, to make this process a bit easier.

This process will work with STL files of contain basic prismatic shapes such as lines, arcs, circles, splines, etc. It is not intended to be used on "free form" STL files.
