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?

Hi guys...

I have a simple solution. I was able to duplicate the problem and I see what you mean about the datums not hiding on a layer properly. However, I have a fix that works and does not require using "On Geometry" or turning the datum into an Annotation Feature.

If you truly don't care to see or use the model-based datums but only intend to view them in the drawing, then set your datums using the old style datum format. See below...

Your datums look like this in the model:

But they look like this in the drawing:

Best of all, they behave in the model they way you'd expect. They hide themselves on layers and yet show up just fine on a drawing. True, this is a workaround of sorts and if you need to see that new style datum in your model, you're stuck having to disable/enable the display of your datums using the Annotation Display toggle switch. But if you do NOT need to see them in the model... using the old style "set datum" propertiy fixes the problem.

Thanks!
