补充资料：工程图标准尺寸及坐标尺寸
标准标注类型，是我们常用的标注类型。而坐标标注是便于数控加工采用的另一中标注形式。PRO/E可以将两种标注方式进行转换。
· 3.2 标准标注到坐标标注的转换
注意： 转化为坐标标注的尺寸必须是线性标注的，下列尺寸不能转化为坐标标注：
- 被显示成线性尺寸的直径
- 中心线尺寸
- 选择MODIFY DRAW > Dim Params > Dim Type > Ordinate Dim > Create Base.
- 选择作为参考基准线的尺寸
- 选择基准的引出线，该点为0点
- 选择 MOD DIM TYPE > Lin to Ord .
- 选择线性尺寸：注意：必须选择具有相同基准的尺寸
========>>>>
1. 选择 DIM PARAMS > Diam Dim Type .
2.点击Ord to Lin 
3.选择尺寸即可
