Name

Point boundary from elements (PointFromElements) — Construct a point boundary surrounding a set of elements.

PointFromElements(group)

Base class: BoundaryConstructor
Parameters:

group

Construct the boundary from these elements Type: The name of a element group, or the placeholder selection, referring to the currently selected elements.

PointFromElements is a BoundaryConstructor, used as the constructor argument of the OOF.Skeleton.Boundary.Construct command when building Skeleton boundaries. It creates Point Boundaries from the currently selected Skeleton Elements or from a group of Elements. The Elements are specified by the group parameter, which must be either the name of a Element group or the special placeholder object, selection.

Like when constructing an edge boundary from Elements, and unlike when constructing a point boundary from Segments, only the points on the exterior of the Element set are included in the boundary.
