测量值能否直接写到工程图上?

ning84

测量椭圆弧长，相当简单。
但是要将测量到的椭圆弧长直接写到工程图时，找了半天没有找到相关的示例。

请问：测量值能否直接写到工程图上的示例吗?

smartlz

不能.
在工程图上,手动,插入注解,输入在零件图上测得的弧长.

可以直接标注的——

小问题，直接标准即可，不需纠结

计算焊缝长度,椭圆封头(一般是通过计算获得)的下料.

实现了？？

repzk031

同问,为什么要这样做,增加机加工成本,质验也是很困难的,是凸轮曲线吗?如果是追求机械运动轨迹,何不用其他机械传动替代,如气动,液压.都有标准件,成本容易控制.

fushuixiu

工程图中点取智能标注，先取圆弧头尾二点，再取圆弧任意当中一点，就可以标注圆弧了。

这个尺寸没啥使用价值，多余的

其实这个尺寸在很多时候意义很大，只是楼上各位没有用到罢了
