请教一个SW的尺寸精度问题！

我想问问各位，你们在标注尺寸时，是在造型时就加入精度要求，还是在工程/出详图中加入尺寸精度，哪个更符合操作规范？
  
oops018：
一般來說我是看我的工作需求  
我的工作精度一般都只開到小數點第二位數  
也就是絲的單位...因為我的工作性質屬於機械加工類  
但有時也有開到七八位數的小數點  
因為需要算到齒輪係的相關中心位置  
最後才依所需的加工精度標尺寸公差  
你們認為呢!!?

我觉得没什么规范可言，不如说习惯，而习惯是自己的。。。

我做圖一開始就以小數4位，精度設成4
以比較高的精度繪製3d
在給下游承接時，成功率會提高

尺寸公差等加工符号是否在造型时就考虑呢？
  
我的习惯是后期加入，以免尺寸显示看不清。造型完成及装配环境验看完成后，进行特征整理时加入。ANSLG

In SolidWorks2000, it was often reported that users were having difficulty with precision problems in their sketches and feature creation. If they used the measure or dimension tool to help determine linear spacing for a pattern or some other function, then they would use the result at the current precision settings. Just because the dimension read 1.25", it did not mean that it was exactly 1.25". It was correct to that level of precision. One way to solve this problem would be to dimension between the desired entities and specifically type in the dimension that you wanted. If the result in the dimension tool is 1.610", then type in 1.610. You will now be guaranteed that the dimension will be accurate. There is now a new feature in SW2001 that should help eliminate part of these problems. When you dimension between two entities, the dimension tool will supply you with the dimension to 8 units of precision. Once you accept the dimension, the length will be displayed with the precision that is set in the document properties. You can now be sure that the dimension is what you want it to be.

新手报到，大家多多指教！

how to deal with it?

我也是后加的！
