Datum planes in a hidden layer will not hide in the model!

Okay, this is driving me crazy.

I have a part, and I've made datum planes on various surfaces of the part so that they show up in the drawing. I do NOT want them to show up in the model. I have added them to a layer and hidden the layer but the planes still wont disappear in the model. If I hide the planes directly in the model tree by using right click, the datums disappear in the drawing.

Please help me fix this problem! I've had mutliple people look at it and I'm about to give up and "fake" datums in the drawing instead of having them in the model. Like I said - they are in a layer that has been hidden but they wont go away!

I appreciate the help!

Yes, the property of adding a datum tag as you show.

I just confirmed this is still a "problem" in Creo 2.0. Or at least it is very unpredictable. It seems to act differently when using Annotation to control display then using Hide/Unhide. I still haven't found the logic. I think in Creo 1.0, it is even more unpredictable. Also be careful, in Creo 1.0, I had many hard crashes when moving the datum symbol around. Save often!

You probably have datum symbols applied to them. I have had this problem and find this absolutely annoying. I've quit using, or even try using the ASME Y14.41 method of annotation.

If you remove the symbol attribute from the plane, it will probably act normally again.

Just for the sake of completeness, what version are you using?

I'm using Creo Parametric 1.0.

By symbol, do you mean the display option or something else?

Now it has a host of new problems. It still doesn't hide the plane with the show/hide datum button although the layer hiding does work. I also could not get a second instance of the datum to display in the drawing where the annotated datum would.

The fact that the annotated datum has specific display control is a plus. I think last time we discussed this we came to the conclusion that having datum planes and axes specifically for the callout was a preferred method of defining the datum tags for drawings or 3D drawings. At the time it was Creo 1.0 and it still had major issues with crashing when you moved datums. I settled for symbols in the drawing over datum tags. I'd be willing to give it another go with Creo 2.0 to see if it has become more stable. But I must have control over display of the datum planes when modeling.

You don't get the option when the tag is attached to a plane or axis, but when applied to a geometry surface, the datum becomes "subordinate" and you get control over its display. This is much preferred unless I am overlooking something.
