Then a high-quality 3D software Blender was created, which was designed for mesh modeling, but not for parametric 3D modeling (NURBS) that is much more practical for technical professions. Gradually, free 3D CAD software appeared, however, mostly useless from a practical point of view. This led to the situation that such software spread to other types of industry, as well as to small and medium-sized companies, but the problem still remained that its price was too high for some small workshops, enthusiasts, personal use or companies making small profits. Over time, the market showed a demand for cheaper software, and software such as Solid Edge, Solid Works, T-FLEX, Rhinoceros, Inventor etc. The first 3D CAD software (Ideas, Unigraphics, PRO/E, Catia) was designed for the aviation, space and military industries, i.e., industries with big profits, and thus the pricing of this software was excessive to smaller companies.

Nowadays there is a variety of high-quality parametric 3D CAD software which greatly facilitates the work in the field of different engineering professions.
