Considerations on 2D constraints for drawings made with existing design software

Résumé

This paper aims at present the author's personal reasons on the set of dimensional constraints existing in each design software, that are designed to achieve certain parametric sketches. In general, constrained sketches, whatever sided they receive as value-dimensional constraints; remain permanently in the same family of geometric shapes. The study was conducted on the following design software: Mechanical Desktop 6 or NX 7.5 and Solid Edge v.20.
