Yep 
I use 4 places by default so I can see the results of fractions or whatever reason the 4th digit accuracy is invoked. However my drawings all use 2 and 3 decimal places. It forces me to evaluate every dimension to know that they are nominally correct.
For instance, I may use 5/16 as an entry value which is .3125 and on a drawing, it should be .312 or .313. I make sure that my model and drawing are exactly the same so I edit the value in the model to be correct to the number of digits on the drawing.
I learned this when an employer that wanted to have every dimension with its own tolerance instead of relying on a title block tolerance. This forces you to think about every dimension. A bit overkill but I understand the principle.
However, these practices do force you to edit every dimension. In the grand scheme of things, it it not so bad. It really does make you be better engineer in the long run. ...and you get respect from the manufacturer that uses your model since the -drawing- is the "contractual" master to them, and they should agree 100%.
