       曲线板是用来绘制曲率半径不同的非圆曲线的工具(图)。绘制非圆曲线时，可用曲线板或由可塑性材料和柔性金属芯条制成的柔性曲线尺来绘制。
      (1)作图时，为保证线条流畅、准确，应先按相应的作图方法定出所需画的曲线上足够数量的点，然后用曲线板联结相关点而成。
       (2)具体的用法及步骤是： ’
       ①按相应的作图法作出曲线上一些点；
       ②用铅笔徒手把各点依次连成曲线； ’
       ③找出曲线板与曲线相吻合的线段，并画出该线段；
       ④按同样的方法找出下一段，相邻曲线段之间应留一小段共同段作为过渡，即应有一小段与已画曲线段重合，以保证最后画成的曲线圆润、流畅。
