  • Reusing the same datum symbol for differnt parts on the same sheet . . .
    If it is the former, then the datum A in the assembly view is a unique datum and there are no issues aside from it being confusing If the latter, then you can technically "repeat" the other datum as well and have two datums A on different features of the assembly
  • Can we mention a datum twice in the same drawing? | Eng-Tips
    Vikas Jangre: This is acceptable You can repeat the datum symbol w ith the same letter as many times as you want, as long as it is applied to the same feature (in another view section)
  • multi sheet (or view) repeat datums - PTC Community
    However, in Creo 7 0 1 drafting, when I add datum symbol (s) to the same reference in another view, Creo automatically assigns the next letter - and then Creo complains when I edit it to what it should be, and flags the symbol as a 'duplicate' (despite what the ASME spec says)!
  • Relating the Secondary Datum Feature to Primary Datums
    This is because multiple features could share the same centerline, center plane, or axis, making it difficult to determine which feature should be prioritized as a datum feature for inspection or manufacturing purposes
  • The Datum Reference Frame - GD T Basics
    Other feature control frames that list the same datums with the same order and the same modifiers will also be inspected to this datum reference frame This is known as simultaneous requirements
  • Same datum (say Datum B) be attached to the same feature be shown in . . .
    Yes, it's ok however, I prefer to show datum specifications on my engineering drawing at just one place - usually on the first page Drawing clutter rarely helps in addition to the possibility of miss-attaching the datum or future drawing changes that could result in confusing datum specifications
  • Beginners Guide to GD T - Datums - CNCCookbook
    When we refer to the tangible feature on the part that the Datum is associated with, we call it a Datum Feature The reason they're not the same is perhaps small, but significant
  • Make Certain You Have Controlled Your Datum Features! (#69)
    In most cases, datums are established from the extremities or high points of datum features, through the use of a datum feature simulator for each datum feature referenced in a feature control frame
  • Mastering GD T - Building Datum Reference Frames
    Each example will show the 3D geometry along with the proper datum feature callouts on the drawing These examples will be in increasing order of complexity and will include a discussion of part and assembly design intent and how it relates to the chosen DRF
