System Philosophy

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.
