Click the
button in the toolbar. -
Select Faces > Main Tools > Modify By Sketcher from the menu bar.

Select Parting Surfaces > Modify By Sketcher from the Mold Design Guide Toolbar or Parting Guide Toolbar.
Modify the boundaries of a face by projecting them onto a plane and manipulating them with the Sketcher tools.
The picked face and its boundaries are presented as a sketch with the origin of the UCS positioned at the corner U=0, V=0 or the closest corner to it (from which the X and Y directions are taken).
Splines are treated as "Control Points" splines for improved editing capability.

Face Boundaries |
This is a toggle option Face Boundaries / Original Surface that enables you to perform operations either on the face boundaries or on the original surface. Face Boundaries is the default option. The original surface is calculated in the minimum parametric box as + 5% of the face. The limits of the original face can be modified by manipulating the box. If modified contours intersect the boundaries of the original surface, it is enlarged accordingly. Each of these options displays different parameters, as shown in the examples below.
