Using the Mesh Section Sketch Tool to Remove Extra Faces From Your Model

In a previous post I show you how to use the Mesh Section Sketch tool, in Fusion 360, to convert a STL into a solid body.  This post will use the same tool to remove excess faces from a model by cleaning up the sketch it was created from.  Often imported sketches or sketches which were created using excessive spline points will cause these excess faces.  The process can be used as shown, starting with a sketch, or it can be used on a surface extrusion created from an existing model.  In the short video you will see how simply and effective this method is.

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.
