The declared aim of SISCAD-P is to relieve the user of
all tiresome but necessary tasks during all phases of
the new construction (e.g. modifications, dimensioning).
In addition, the system supports in areas where the use of
CAD was unthinkable up to now (e.g. sketching, automatic
variants or saving the logic behind a construction).
Thus, a permanent data flow is guaranteed, redundancies are
not necessary any longer.
SISCAD-P is a CAD-system with a parametric core. On the one
hand the user may work with it like with any other usual
(i.e. not parametric) system, on the other hand the user
has all the parametric functions also available. The decision
which method to use is dependent on the respective problem.
The operation of the system is very easy for both applications.
For parametric construction only additional functions are
necessary, i.e. there are more possibilities.
Modifications are for example restricted to the adding of new
dimension values, the logic of the drawing remains unchanged,
so the user wants to have the changes made automatically. Here,
normally variant programs are used. Due to the fact that for the
creation of variant programs a lot of programming experience is
necessary, the parametric working method should be preferred.
The basic differences between the different parametric
CAD-systems originate in the internal parametric model.The
realization of this model is the key for the user-friendly
use of the respective system.
