If you want to be a draftsman, a machinist, a molder, or a patternmaker, you'll need algebra and geometry and even trigonometry.

如果你想成为手工艺人、缝纫工、造型工或制模工，你需何，甚至三角学。

Consequently, the stand or fall of patternmaking master technology will affect the integral quality of the mould directly.

因而，制模师傅技术的好坏将直接影响到模具的整体质量。
