# Decimal / Fractional Units

My company has tolerance blocks based on 3pt, 2pt, 1pt decimal dimensions, and fractional dimensions.

If I change the units to fractional, 2.000 is displayed as 2, 1.50 is displayed as 1 1/2, etc.  I need them to stay as decimals while leaving other dimensions as fractional.

Can I adjust the units individually as decimal or fractional?

No you can set the individual unit as decimal or fractional but you can set individual dimension as decimal or fractional. You can create dimension favorites and use them as you need.

You can also use override dimension check box and type in what you want.

in solidworks 09 for sure but i think 08+ you can override the dimensions units and all that individually by clicking on the dimension and going to the other tab and clicking the override dimension button, refer to attached pic.

Thank you, that is exactly what I needed.

In 2010, this is also possible. My question is why do you then have to go to the value tab to set the number of decimal places? In 2004 this was a 1 step process and now it is a 2 step process? I can't seem to set under options that I want all my dimensions in fractions, but if I choose to overide them to decimal, I need them to be 3 decimal places. Is it possible?

It has been my experience that it is far more efficient to simply apply an appropriate tolerance to the feature dimension, (preferrably in the model), than it is to police every dimension on the drawing and convert it's presentation to conform to title block blanket tolerances.  The former method is also more prone to error.

Title block blanket tolerances are a hold-over from the days when sheets of vellum were preprinted with the company's title block.  Not a "Best practice" today IMHO.
