It does not make sense to save the constructional relations after each
CAD command.
The possibility to save constructional relations is available for all basic
constructions, i.e. the CREATE commands for points, lines, circles and
nearly all COPY commands.
In general for each command, for which the optional parameter
SAVREL is offered, the constructional relation can be saved in SISCAD-P.
There are 2 ways to save constructional relations:
The constructional relation of an object is saved.is activated, the corresponding constructional relation to each newly created geometrical object is saved in the course of the construction. Provision is that parameter SAVREL exists and is not set on SAVREL=0 .
