drafting quotation 2d 'sprit'

[vinci16]

hello to all, I imported a drawing from a colleague but strangely all odds do not see, only passing with the mouse pointer above them it is possible to see them.
Can I solve the problem somehow?
Thank you all for your help.
I leave an indicative image of the problem attached.

imported or opened?
do you have the software version?
Is he just doing it with that design or with others?
with ctrl+q, what is settled?
if you enter new quotas you see

Sorry for the few details:
- the file has been opened and not imported; the only peculiarity is that I had to change the references having been moved the files from one folder to another, something that never caused me problems;
- the software version is the same;
- only this particular design does to me;
- with ctrl+q I have not solved the problem;
If I put in some new odds, I see them normally.
today my colleague opened the file and changed the references him, the problem was solved on his pc and consequently also on my.
