## Parametric Concept

Due to the fact that SISCAD-P originally has been designed as parametric system the parametric part is no additional module but an integrated part of the system. Thus the operation of the parametric functions is analogous to the other CAD- commands and for this reason corresponds to the requirements of system ergonomic.
The parametric concept bases on three columns: constructional relations, constraints and variables-functions-formulae.

- Constructional Relations
- Constraints
- Variables-Functions-Formulae
