Wrong Dimensioning?!

[Miha_M]

I was doing some detailing in Archicad 16 INT. On a scale 1:5 I placed some dimensioning and discovered an error. It's no big deal, but this seems to be a problem/bug in Archicad.
...and yes, I have doublechecked it. It's not a drafting error.

You have 'extra accuracy' enabled in your dimension, or accuracy is set to 4 decimal places, or something.

Did you see the screenshot? You can see the accurate distance in my measuring and in the upper coorinate box, both marked in the screenshot. The extra accuracy IS enabled, the draft is ok, but the dimensioning line is wrong. As I told before... "...and yes, I have doublechecked it."

So what happens once extra accuracy is off?

My point is that the tracker has less finesse than the dimension.

Probably the measuring will be ok if I would change this setting. But I have some other things in this detail drawing, which have to be dimensioned very accurately (3rd decimal @ metric, meter is the basic unit), so turning the extra accuracy off is not an option. As I told before, it's not a big deal and not a problem as such, I can still change the measuring number by myself manually, but it seems Archicad has some kind of a bug here, or is the accuracy correct only at the second decimal number in general? I don't belive it should be.

I would suspect that the distance between the two points is really 0.01895.
The Dimensioning can show this value accurately if extra accuracy is set to show enough decimals.
However, the maximum number of decimals the Tracker and the Coordinate Box can show is 4 decimals so it will round up the value and display 0.0190.

Please try to check or redraw the elements to make sure they are exactly 0.1900 apart.
