Thanks for the other 2 solutions, but it makes perfect sense to remove the repetition!
After what bothers me is that during the drawing, I wanted to show the number of occurrences: by having the real number from the repetition, it would be easier! (and that's probably why I wanted a repetition at a single occurrence).
I would have a solution but on Creo because I don't know if it's done on SW.
When we do a repetition we can deselect certain occurrences that we don't think are useful, so in your case if you do a repetition of 2 and you deselect the 2nd cylinder it could work
Do a "parallel" drilling function of your cylinder. And put it in your repetition. In your drawing, you discreetly insert a "Symbol for drilling" and you modify the comment to say write "x cylinder"
@Tomalam: this is a function that also exists in SolidWorks, but when I remove an occurrence, Solid tells me that it is impossible because it is a repetition without repetition!
@Pascal at home in 2013 it doesn't work either! A matter of the options of the function? (see image)
@Lucas
I warned that it was a hack!!
You make a small piercing somewhere that you can't see (like Ø0.15) and you repeat this piercing with your jack repeat. In your drawing you dimension it with "Symbol for drilling". The number of entities will be good and you replace the <DIM> initially for the piercing by "tartampion cylinder".
