Decimal places dimensions & tolerances

Is there a way to place a dimensions with 1 decimal and the tolerances with 3 decimals ( 152 +/- 0.025)?

I hope the correct answer is no.

The reason I say this is because of rules Per ASME Y15.4 (2009).

Some passage citings for reference:

for inch dimensioning:

Paragraph 1.6.2 Decimal Inch Dimensioning:

(b) A dimension is expressed to the same number of decimal places as its tolerance. Zeros are added to the right of the decimal point where necessary.

Paragraph 2.3.2 Inch Tolerances:

Where inch dimensions are used on the drawing, the following apply:

(a) Where unilateral tolerancing is used and either the plus or minus value is nil, its dimension shall be expressed with the same number of decimal places, and the appropriate plus or minus sign

(b) where bilateral tolerancing is used, both the plus and minus values and the dimension have the same number of decimal places

(c) where limit dimensioning is used and either the maximum or minimum value has digits following a decimal point, the other value has zeros added for uniformity.

(d) where basic dimensions are used, associated tolerances contain the number of decimal places necessary for control. There is no requirement for the basic dimension value to be expressed with the same number of decimal places as the tolerance.

For metric dimensioning:

Paragraph 1.6.1 Millimeter Dimensioning

(go see this one for yourself - doesn't pertain to the question)

2.3.1 Millimeter Tolerances:

Where the millimeter dimensions are used on the drawings, the following apply:

(a) where unilateral tolerancing is used and either the plus or minus value is nil, a single zero is shown without a plus or minus sign.

(b) whre bilateral tolerancing is used, both the plus and minus values have the same number of decimal places, using zeros where necessary

(c) where limit dimensioning is used and either the maximum or minimum value has digits following a decimal point, the other value has zeros added for uniformity

Set the decimal places as shown.

dimension looks like this:

This is what I was looking for, but is there a way to put this in config.pro so when don't have to do it manually?

I don't see a way to set the configs for the tolerance decimal places to be different than the part decimal places.

configuration setting is: default_dec_places

You can combine default_dec_places with the defaults for tolerance values: 'linear_tol 2 0.125 3' indicates that the default tolerance on a dimension with 2 decimal places in the value should be 0.125 with three digits for the tol. Note that these 'linear_tol' values are incorporated into the solid model on creation, and making a dimension in a solid uses the values in the solid.
