Create and Combine Areas (Regions)
Regions are 2D enclosed areas that have physical properties such as centroids
or centers of mass. You can combine existing regions into a single, complex
region.
Regions can be used for
■ Extracting design information, such as areas and centroids, using
MASSPROP
■ Applying hatching and shading
■ Combining simple objects into more complex ones with Boolean
operations.
You can create regions from objects that form closed loops. Loops can be
combinations of lines, polylines, circles, arcs, ellipses, elliptical arcs, and splines
that enclose an area.
You create regions using the REGION command to convert a closed object
into a region, and the BOUNDARY command to create a region from an area
enclosed by objects. You can combine regions by unifying, subtracting, or
intersecting them.
Objects combined using UNION:
