Use of Topology Points

The general principle for the use of topology points is that references to topology points should be supported everywhere in plane hull modelling where explicit coordinates and directions can be given in input. This means for example, in assignments to keywords like U, V, X, Y, Z, T, but also in curve statements without any keywords and in the keywords for space points (ORIGIN, UAXIS and VAXIS).

Exception to the general rule is that topology references are not supported in the PANEL and plane (PLN) statements.

Reference may take place for individual coordinates and directions but also for/to a point as a whole.

This is described in detail in General Layout of a Statement.
