For all selection methods, the OK command is enabled once a closed loop is defined so that you can select more loops. By selecting more loops, you can define inner and outer loops that make islands in the surface. If a planar region is selected, selection of extra loops is not allowed. Tips for creating boundary patches: • If you create a boundary patch with tangent constraints, avoid using supporting faces that are all perpendicular to one single imaginary plane.

An angle that is not 90 degrees is expected. • Avoid creating a boundary patch on construction geometry that consists of a single segment closed curve (circle, ellipse, or closed spline). • For best results, stitch boundary patches to adjacent surfaces before creating features, such as sculpt, shell, and thicken/offset.
