我個人很喜歡這個帖子，其問題本身的重要性暫時可以超過其結論。還希望樓主大俠幫助我和大家共同學習提高。

Put it in this way, one single line element in a specified view could be considered as a 2d line, but multiple line elements in same view and in certain interval can establish a cluster of lines that can be considered as a kind of 3d image. Furthermore, multiple cross line elements in front view and side view can set up a net construction image that will be able to describe the flatness well enough. That's why some persons think that the new version Y14.5 would regulate the cross views straightness equal to flatness of a planar surface.

行勝于言

我怎么覺得0.6還好理解。兩條直線可以決定一個平面，但平面可以上下浮動啊

Think about this problem really helps. I have to say that thank you for your good job. Have a nice weekend,

第一題，應該是考慮了最大的尺寸界限，兩直線度的公差要求，顯然要小于尺寸公差，取最大，故是0.6，第二題，4.6；相對C基準的尺寸，只有20，以及位置度要求的偏差，減去孔的最大半徑，可得4.6
