Hello,
Currently the way the grid lines are built is a slow process (mostly copying), especially if we try to do building grid having all over different spacing between the grid lines.
Please have a look at some other software starting with R and another one starting with T-there is an option to change the distance between the grid lines by entering the values straight in the dimension line, and all others are moving keeping the distance between them unchanged.
Kind Regards,
