Hi

I am working on a machined casting model with detail drawing. I would like to know if I can create a dimension line ( In annotation, create Dimension), the dimension line of cylinder will be used as to attach datum symbol ( the certer axis of the cylinder), however the cylinder is NOT machined, so I would like to del dimension data, only shown witness line and dimension line, NOT data. I try several times and search all community can not find any similar situation. could you please help me.

up to now I do NOT want to use creating new customized symbol solution.

PS: who know where has good GD&T forum, now my company ask all drawing need to follow GD&T Y14.5M-1994, I met some really hard problem, thank you in ahead for any hlep.

Best regards, Hongjie

Use a created dimension and replace the @D with @O (letter 'O', not​ zero; "switch dimension value Off").

From memory, you may have to play some tricks to get the datum flag attached to a created dimension - I think I've created it attached to an axis and shown it in the drawing; then re-defined it in the drawing to change its attachment to the dimension.

Personally, in this situation I usually leave the value visible but make it (reference).

    Hi Hodgson,

    Thank you!

    I try several times change @D to @O in Dimension Properties manue Display tab, even choice Override Value in Properties tab and Tolerance Value only and so on, all action can NOT del data, the best result is give a break in the dimension when choice Tolerance value only. Per company request we use ASME Y14.5M annotation, data in medium of line instead of above the line.

    It looks Creo 2.0 can not use @O trick, I remember I can do the override in Wild Fire 4.0 previously.

    Finally, I choice to set it to reference dimension which make job easy, thank you again.

    Best regard, Hongjie

    Were you trying to use @O in a shown, or in a created dimension?  AFAIK it only works in ​created​ dimensions.
