Variabilized technology's application in mine-machine CAD

摘要

Variablized technology and parameter CAD technology both belong to entity sculpt technology, which is based on constrict. But the former has some radical changes on disposing method of constrict. Variablized technology further divides geometry constricts into shape-constrict and measurement-constrict, and deals with them separately. It can also evaluate the equation by joining directly constraint condition and geometry equation. Variabilzed technology can be adapted to all kinds of constrict instances. The designer can first confirm the shape in which he is interested and then give some necessary measurements.
