Toolpath Inside of Model (Multi-Axis Feature) - Reverse Surface Normals
This document will describe how to fix surface normals for a multi-axis feature. You may need to do this if you see that the toolpath was created inside of the model. The reason this is happening is because of how the surface normal is orientated on that surface.
The example below shows a multi-axis feature using Parallel Cuts for the surface toolpath.

1. Go to Utilities Reverse Surface Normal
This will show which way the surface normal is facing and will allow you to reverse the direction of it.
