Dimension view status is linked to datum plane status using layers
I am using Creo Parametric 7.0, 7.0.2.0,
At drawing application, when using "Show model Annotations" in order to bring out specific dimensions from the CAD model, for example, a 3D annotation derived from a datum plane (the dimension in question is the offset dimension from a datum plane to another datum plane in order to create it), it's shown correctly on a particular drawing view, but if the datum plane on the drawing view is hiden using layers, the dimension it's also gone, leaving only a suppressed dimension on the drawing tree. If the view is manually updated, the dimension is back, but if using "Draft Update", the dimension is gone again. The dimension it's left in a status of showing but then gone if the drawing is updated. Apparently CREO consider the dimension also a datum plane.
Thanks for any advise.
