Heights tab

By default, the Horizontal finishing strategy also machines across the top of the part and the small flat areas on the ridges of the part. In this operation we are only concerned about the bottom flat face, and so we can limit the depth range that is to be machined.

1. Click the Heights tab.
2. From the Top Height drop-down menu, choose Selection.
3. For the Top reference, select one of the vertices above the bottom fillet as shown below.
