Boundaries > Create > From
Spline - creates a spline based on the user’s placement of
control points, and converts the spline to a boundary.
Boundaries > Create > From Selection (available when at least one polygon is selected) - creates a boundary line around every contiguous set of selected polygons, or specific groups of selected polygons. Left-click a single group to create a boundary around it, Ctrl-Left-click a group to remove the boundary from it, or use the Create Boundary From Selection dialog to mark all or clear all boundaries from selected groups of polygons.
Boundaries > Create > From Polyline - creates a free-form closed shape based on the user’s placement of control points, and converts the shape to a boundary.[In Geomagic Qualify at Edit > Boundaries > Create > From Polyline]
Boundaries > Create > By Crease Angle - creates a boundary line between every pair of adjoining polygons whose normals differ by a specified angle or more.
Boundaries > Create > Along Non-Oriented Edges - When point objects have been merged and then wrapped, it may appear that the yellow back-side and blue front-side in certain areas of the polygon model are reversed. In that case, use Tools > Make Manifold to delete extraneous polygons, and if the problem persists, use this function to create a boundary line between front-facing and rear-facing triangles and then use Polygons > Boolean Operations.
