In older versions of Creo, i.e. Creo2, you could show Datum Tags from the base model that was used in a Merge/Inheritance feature. In Creo4 they will not show up. This is how we typically create our sand casting drawings. The sand cast core model will have a Datum Feature Symbol (Datum Tag) on a bore, for example, and we want to show that datum in the drawing.
Can anyone help with this? TIA.
In Creo 2.0 we used to show the set datums of the merge (core) in the Casting.
But in Creo 4.0 there is no concept of Set datums. We directly create DFS on the drawing.
So you could create the required datum as a DFS on your drawing.
We tried that also. But Creo4 would not let us attach the DFS (Created in the Drawing environment) to the features of a sand core body(the merge/inheritance feature). It would only let us select the entire merge/inheritance body. You can't show the dimensions of the core body to attach the DFS to. I hope that makes sense.
Ok. I CAN show the core dimensions but I can't attach a DFS to them. I click the witness line and middle click off the line and the DFS disappears.
