Datum sequence definition

[marcin.blaszczykRU3XC]

Hello

this seems to be easy but I just can not get rid of this message.

I am establishing three datums using Tolerance Feature button but Tolerance Advisor shows  that DRF is not referenced.

So I click DRF button to assign these datums (can not be done opposite way cause nothing can be selected in DRF dialog box) - and then it says "Datum sequence already defined"

What am I doing wrong here??

😐

Hi Marcin,

I believe it means "ABC" has not yet been referenced by any of the tolerancing feature. It is just a warning. You can ignore it. Regarding DRF feature, it defines the datum sequence. You already have ABC. You can define DEF accordingly.

Many thanks!
