Dimensions rounding?

[Anonymous]

Hello,

Is there any possibility (or maybe plug-in?) to set accuracy of dimensions (rounding)?
For example: original is 1881mm and I want 1880mm.

PLEH!! (to be visible in Revit's rear-view mirror)

I still think this may create a problem. I usually work in cm and have extra accuracy on, so if I see the small digits behind the main dimension, I know something is wrong. If somebody rounds up the dimensions I could discover the incorrect work weeks later or become a laughing stock of the structural engineers, when I sent them the project. Construction may not be a millimeter perfect, but modelling and drawings are. Just my opinion.

I agree.
If I want to round something to 5mm then I model it to the nearest 5mm.

5mm is not a standard unit of measurement but 10mm is (1 centimeter)
It is possible to set your working units to centimeters (with zero decimal accuracy) and still have your dimensions set to millimeters.
This way if you model accurately then all dims will be in 10mm increments.

..................... well said Barry, totally agree.

When doing renovation work, which was probably built during imperial days,
and you measure as constructed you are faced with odd dimensions all the time.

The problem with rounding is making up the difference if the sum of rounded dimensions don't equal the total overall dimension. This is a quite normal situation.

When drafting manually, drafters used rounded dimensions and an overall dimension - but deliberately left one dimension string blank. Its value was determined by subtracting the sum of the strings from the overall dimension. If you want to round in Archicad, you could do the same. Otherwise one would have to leave it up to the computer to decide where the difference is made up and this could be problematic.

A variation on Kees' hand-drafting solution was instead of leaving one dimension in the string blank to put a +/- before one of the dimension.

You can switch to cm and set it to round,
so you will have 180cm displayed on your dimension lines
even if your model is 1801mm or 180.1 cm!
