The Blend command creates a surface blended between 2 surfaces or curves. It can also blend among three or four surfaces or curves. SURFCAM attempts to maintain a tangent, or smooth, connection to the selected surfaces. In some circumstances a tangent condition cannot be calculated. When this occurs, SURFCAM automatically provides the option to apply an angular tolerance.
With the Blend dialog box options you can control the effect of the surface tangencies on the blended surface.
