Is it a bug?
Each view has its own settings and in those settings you can assign a a dimension style.
So you can have multiple views of the same view point - but all with different settings if you want.
So in the Navigator there are four buttons - one for Project Map, one for View Map, one for Layouts and one for Publisher Sets.
The Project Map contains your View Points.
You control all of the settings here manually.
i.e. you can set the dimension style, layer combination, scale graphic overrides etc., to what ever you want - and that is what you will see on screen.
Then what you should be doing is saving a View of each View Point - these will be saved in the View Map.
Each one of these views 'saves' the settings for things like dimension style, layer combination, etc.
So when you choose one of these views, all of the settings will change automatically to suit what you want it to be.
It is these Views that you then place onto the layouts - that way they remember what settings they are supposed to have.
You then Publish these layouts.
So once you have it all set up, with all the views you want and have them placed on your layouts, you simply make changes in Archicad.
You can use the Project Map View Points to navigate around your project - but remember you have to control the settings your self so what you see on screen is correct.
Or you can use the View Points in the View Map and the settings will adjust automatically for you as they were set in that view (and yes you can change the settings if you need to).
So if you are using the Views in your View Map, make sure that in the settings, they are set to use the decimal (centimeter) style.
Also when you change the dimension style, be sure to "Store As' one of the styles to make it a permanent change to that style.
That style is what you apply to the view settings.
You don't want it to ever say 'Custom'.
