Hi Ismet
Sorry for not fully understanding.
I think you want to apply just the 2 holes at the front and back of each shelf? 50mm and 82mm center lines? so no 3rd hole close to the front and back edges?
I could be wrong, but I don't think you can add two different patterns to the same edge? (Does anyone else know?) that's why I made the pattern reversible, (seems to me the unwanted, unneeded hole gets covered anyway)
And so to change the 60 to 50mm just change the construction parameters in Ecabs and save it
Again I am sorry, I think I am not fully understanding.
Also as per your attached cabinet you have used constraints for the second holes, they seem to work good? and do what you want them to do? so as I said i don't fully understand, you may have to explain more what you are trying to do?
Does anyone else understand what Ismet is try to do?
Sorry for the confusion
Mark
