The UNION command
The
UNION
command (alias
UNI
) joins two or more objects into one. The command
can be applied to solids, surfaces, and regions, but it only joins objects of the same
type, that is, it can't join solids with surfaces or regions. It only prompts for the selec-
tion of objects to join and returns only one object:
Command:
UNION
Select objects:
Selection
Duplicated volumes or areas are removed.
The command can be applied to solids that do not share a common volume or re-
gions that do not share a common area. In this case, we get one object despite hav-
ing separated volumes or areas. As it is not possible to join 3D meshes, upon its
selection the command prompts for its conversion to solid or surface.
