MOLDRAW allows to hide atoms of the structure without actually
removing them form the original structure. This is at variance with the
structure manipulation which is
always destructive.
An atom can be hide by clicking the Hide Atom label on the toolbar, or the structure can be clipped along the Z-coordinate.
Other operations like hide part of the structure following planes cuts, or circle and spheres shapes are possible. Hiding all atoms of the same kind is also
allowed.
