I like to use the Model Items tool for part drawings because it creates a strong link to what I am dimensioning that can be driven back to the part from the print.  Problem is that sometimes I hide or delete a dimension I didn't think I needed and then find out later that I did.  When I go to show Model Items again those items that I right clicked to hide or have deleted individually don't show up again.  It sure seems like there should be a way to bring these back since they are still in the model.  I have all of the boxes checked in the "Dimensions" dialog sidebar section.

I am sure that there is some simple thing that I don't know how to ask for and that is why my attempt at google failed.  Thanks.
