Silhouette Regions, 3 Axis OperationsThe silhouette regions are used to compute the contact regions based on the selected tool and the visible part geometry.  The system will compute the regions where the tool can safely traverse in such a way that the entire part geometry can be machined using the computed region geometry.  Silhouette regions can also be thought of as the Tool Contact Area Regions.

Alert!Note that these regions are dependent on the orientation of the tool axis.  That is for the same part geometry approaching the geometry in different orientations will cause different regions to be computed.

An example of this is shown below.  The surface shown below represents the part geometry to be machined.

The computed tool silhouette area regions are shown displayed in red, below:

Now these regions can be selected in subsequent machining operations to compute toolpaths that will completely traverse the part surface to be machined.  An example of a toolpath utilizing these computed regions is shown below.  

Alert!Note that the same tool that was used to compute the regions will have to be used in the toolpath computation also.  Otherwise the tool might not be able to traverse the entire area of the part surfaces.
