## Minimum perimeter enclosing rectangle

Compute the minimum perimeter enclosing rectangle of a point cloud in the plane.

Access methods

8 Toolbar: 7 Command entry: CC:HULL:MINPERIMETER

Dialog

Select points:
Select the points for which to compute the minimum perimeter enclosing rectangle.

Specify projection direction [X/Y/Z/Ucs/2Points]:
Select the projection direction.
<X>:             The rectangle is computed in the global YZ-plane
<Y>:              The rectangle is computed in the global XZ-plane.
<Z>:             The rectangle is computed in the global XY-plane. (default)
<Ucs>:          The rectangle is computed in the UCS XY-plane.
<2Points>:     The rectangle is computed in a user defined plane perpendicular to the projection direction. The following dialog occurs:

Specify first point
Select the first point of the normal vector defining the plane.
Specify second point
Select the second point of the normal vector defining the plane.

Notes

The 2d minimum perimeter enclosing rectangle is the rectangle that encloses all points with minimum perimeter length. If the points are 3d points, the 2d minimum area enclosing rectangle is computed for the projection of these points onto the specified projection plane.

Note that the minimum perimeter enclosing rectangle is not necessarily identical with the minimum area enclosing rectangle. Use Generate points on primitives and Generate points on solids to generate input data.
