Hello,I am working on multistory building with repetitive typical floor. When I try to copy dimensions from one typical floor to the next half of them loose reference. I am certain that the references are exactly in the same place because they are repetitive model group as well. I placed the dimensions in a detail group but when I apply it the same half of them disappear. I cannot explain it as Revit allows me to group the dimensions but they loose reference when I apply them to model group instances ?!One other question I have is does it make sense to add small model line segments to model groups as references for dimensions in an attached detail group. Example: "windows model group" with attached "structural openings detail group" and model line segments in the model group to serve as references for wall ends (walls are not part of the model group). I don't know if this is a good practice but I would like to be able to reference objects outside the model group.Thank you for your help, advice!BR, Vangel.

Revit is not CAD.   When you dimension, you are dimentioning to a component.  Dimensions to column lines can be copied floor to floor because the element, the col line, spans multiple floors.   But when you dimension to an interior wall, that wall is typically just one level so the dimension is lost. 

Adding model lines to dimension to is a terrible practice!

Your other question is not clear.

Thank you for your reply. My first question, the important one is why when I copy dimentions from floor to floor, which reference identical model groups instances, I loose dimention references. Revit allows me to group the dimentions as detail group for this model group and still somehow looses references (deletes dimensions) when I attach the detail group.

I hope it is more clear now. Thank you!

You have to edit the model group and add the diomensions there.  But the same rules apply.

I understand. My issue is that once I attach the detail group to the model group not all dimentions will appear, some cannot find reference and disappear. This happens some of the times and I don't know what the reson is. See attached file with model group and attached detail group.

Thanks

Hi , about the problem you mentioned ; I was having trouble with copying dimensions from a level to another. and I did this: 

I created a group consisting my whole floor model and also the dimensions> and then selected the group+ the grid lines( cause apparently many of my dimensions were attached to gridlines) > Ctrl+C > Paste aligned to view in another level . 

I hope it works for you too

I'm sorry faramarzensaf, what you suggest is not good advice.  Again, Revit is not CAD.  Why would you ever copy grid lines to another level, they would already be there.  Copying these will result in new grid lines and they will not have the same number as the ones you copied.  This would result in a MESS.
