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 Brian. When you assign the datum tag annotation to one of the primary datums, it does not follow any rhyme or reason on how or when they are visible or not. It is simply best to not use the, and instead, use geometry.

In the video, see what happens to datum A when you turn off datums. Same as when you hide hide datum A; it doesn't hide. then at some point when you use the datum tag in a drawing, the plane itself hides in the model never to be seen again.

In all, not having layer control or lack of enabling the show/hide datum button makes for a really messy assembly when you are doing screencaps or just modeling. This was always a serious annoyance in the old Pro/E days too.

the method I brought forth in the video is quite stable from what I could tell.
