Create the CAM features

The next step is to decide what machining operations you're going to perform, and create contours or other supporting objects that will be used by the CAM program. I normally use features from the 3D model to create the CAM objects. In this photo, you can see a green rectangle which represents the material which will be machined. The red outlines are the outline of the part. The blue circles represent holes which need to be drilled. I also like to double check the cut, so I offset the red contour diameter of the endmill I'll be using. This lets me make sure that the cutter won't interfere with anything.
