How SE handle the names of the systema variables , I have noticed, that the name is in increments of 1, but when I have added and erased a lot of dimensions , the system , add variables with random numbers , instead of increments of 1 , Does anyone knows where i can get more info about this behaviour? Example : I dimension a square and the system name the variables: V360 v361 v362 v363 Then I add a lot of more dimensions and erase all of them and go back to dimension the square. V3443 v3232 v3323 v3241 So there is no pattern in the second one. ? I dont want to rename all of the variables , because if know the steps and the first name of my variable i can copy and paste in excel .
