What do you mean - change the number of decimal places?
I vaguely recall this is one place where SE falls down a little and it's a one size fits all global setting or something but my memory aint what it was.
Yes, i want the diameter of the hole show in 2 decimal places and on top of that Can I add some kind of tolerance to it. Such as +/-.005 ?
Thanks for the reply
Click on the dimension you want to change and near the top a ribbon bar will show a number of things. /the second box from the left should be the precision where you can change to 2 places and second from the right side of the ribbon bar is an X, you can click on that and add a tolerance note.
