4 The package allows the representation and manipulation of some
5 simple objects in two dimensions (2D). The macro \Lcs{psProjection}
6 can project these 2D objects onto a chosen plane.
8 The syntax is analogous to that of \Lcs{psSolid}, with an
9 obligatory option \Lkeyword{object}, that allows us to specify
10 the type of object to be projected.
12 The general syntax is \texttt{\textbackslash
13 psSolid[object=objectname,plan=plantype,<options>](x,y)}
