Appearance of drilled hole in Simulation?

In this lesson 8, simulation results in the drilled hole showing as a grayish plug but not as material removed. After lesson 9 with the contour cut, the hole shows thru in the quadrant that is outside the contour line, but remains a gray plug in the interior of the part. Side view shows full diameter of drill thru the material. Why might this be?

The drilling operation is removing stock material. The gray plug that you see is the model! Turn off the visibility of the model in the browser tree on the left by clicking on the lightbulb icon. This will help you differentiate stock from model in the simulation.
