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

　



  1. 选择MODIFY DRAW > Dim Params > Dim Type > Ordinate Dim > Create Base.
  2. 选择作为参考基准线的尺寸
  3. 选择基准的引出线，该点为0点
  4. 选择 MOD DIM TYPE > Lin to Ord .
  5. 选择线性尺寸：注意：必须选择具有相同基准的尺寸
