dimensions rounding

[marcocioeta]

Hello to everyone. I am having trouble controlling the accuracy level of dimensions.

I would like to have the odds rounded to zero or 5. How can I solve this?

Thank you to all

Hi,

Go to options -> project preferences -> dimensions and you can select there how many decimals or extra accuracy if you need it:

Be sure to save the view with the new dimension settings, otherwise, it would revert to the initial settings when you re-open it.

@marcocioeta ,

Adding extra accuracy will not round your dimensions, it will simply show extra accuracy - more decimal information.

You can not control rounding.

The hidden decimals will round down if equal to 0.5 or less and round up if greater than 0.5 (or maybe they round up if equal to 0.5 - I have not tested).

Either way they automatically round up or down and you can not control that.

All you can do is set a larger unit of measurement.

So instead of millimeters, you would use centimeters.

Or in stead of centimeters, you would use decimeters.

Meters instead of decimeters.

Then you can control the extra accuracy of any hidden decimals if you need to.

But you still can;t control how it rounds.

The one thing you can control is the accuracy in drawing while creating wall layouts and detail. Make sure that if a dimension wall to wall needs to be a 10.55m for example, that the wall to wall placement is in fact 10.55m. It isn't good enough in ARCHICAD to draw with sloppy accuracy then trying to correct it by fudging dimensions. Rounding has a serious flaw. In a dimension string rounding will create accumulation errors - that is if you add up the dimensions in a string nine times out of ten it won't add up to the overall dimension. (And those dimensions accumulation errors put the responsibility squarely back on the the designer. Contractors love to blame the designer!)

A good tip I think is to set your Working Units accuracy to a higher decimal precision to what you set your dimensions.

For example I dimension in millimetres with no decimal precision. but I like to work in millimetres with one decimal point accuracy.

That way when I am measuring or using the tracker or looking at sizes in the info box, I can see if measurements are slightly off track.

You can also set up a new dimension style with higher accuracy, and just turn it on to check dimensions.
