## Rounded dimension

In detailed drawing, is there a way to specified the "side" that a value should be rounded in a dimension? (upper or lower value)

Hello Pierre

In the drawing, you can set how many decimal places need to round the parameter.
- behind parameter write [.2] - that is rounded to two decimal places

Best Regards,

Thanks for the answer. Maybe my question was not clear.

For example:

Lets say the real value is 0.125

I need 2 decimal places

If the dimension says 0.12, how can I ask it to write 0.13

How can I do that?

Hello Pierre

For newly created rounded dimension set configuration options:

default_dec_places 2

Note: (number 2 defined default number of decimal places 0-13)

In your case - if you have a number 0.124 system rouded it for 0.12 (1-4 is rounded down)

if you have a number 0.125 system rouded it for 0.13 (5-9 is rounded up)

Rounding is specified by a mathematical rules.

If you need a create a custom rule for rounding dimensions you can create your own rule by relation (Tools>Reletions...).

Best Regards,

Your explanantion is logical, put that is not the way Creo works.

I have here in front of me a real value of 0.3125 and Creo rounds it to 0.312

Creating a relation will works but it doesn't make any sense to do it for all dimensions.

I have seen in other CAD software the option of rounding upper or lower. I was wondering if Creo had the same possibility.

Any other ideas?

Is the nominal dimension exactly .3125 in the dimension properties dialog box? With M090 of Creo Elements Pro I get rounding that is consistant with how Vladimir explained, .3125 rounding to .313.

Hi Kevin

I have the same result (0.3125 rounding to 0.313.)

Have a nice day.

Kevin,

I double checked and the real value is 0.3125000

With 3 decimal it is rounded at 0.312

I use WF5 M060

Is this a bug in WF5?

Hello Pierre

If you can - share your file to control it in Creo Elements/Pro 5.0 M090

Best Regards,

What do you mean by "share your file to control it"?

Good morning Pierre

I prepared for you one sketch for checking your system rounding dim.

In the attachment you can find the model with rounded dim. for 2 decimal places.

Note: This model was created by Creo Elements/Pro 5.0 M090

Best Regards,
