Y14.5.1-1994

I have a question regarding Table 4-3 in Y14.5.1-1994.

If anyone else is familiar with the standard and wants to discuss or knows how I can get in touch with somebody I would appreciate it.

  • I cannot find an answer in those sections. It says they must be basically oriented. My question pertains to skew axes. How would we then define basically oriented?
    Are you talking about the point in "2.7"?
    My intent was more of a mathematical curiousity.
    I didn't mean 2.8, I meant 2.7.
    I saw your post and will be waiting for the new standard.


    To the best of my knowledge, (and when it comes to the math standard, my knowledge is pretty limited), basically oriented is defined either by BASIC dimensions on the drawing or if CAD is BASIC by nominal geometry in the 3D model. In the case of two skew lines I would expect there to be one or more basic angles defining the basic orientation to each other.
