3d document - measure/tracker values

Patrick M — Sun, 03 May 2026 21:10:04 GMT

When I take a 3d document of a cabinet, intending on annotating it with sizes, panel layout and assembly directions... the measure function gets really weird.

This cabinet is NOT 21'-9 1/2". This is a 3d document straight from the model. Why does the view scale impact the value in the tracker? Seems nonsensical.

Operating system used: Mac Apple Silicon

In a 3D document you will no longer measure real dimensions with the tracker or the quick measure tool. In fact, the measurements will be all "off", but they won't change if you change the scale.

I think this basically stems from the crude way the 3D doc is generated internally... (like pixel space becoming model space or something like that)

This is one of the things that SketchUp handles great and much better than archicad, the ability to anotate in perspective (still not good enough reason for using that software).

If I remember correctly, using isometric 3d documents instead of perspective can help you get real measurements.

Well, you can annotate the 3d document just fine, that's what its made for.

So using the dimensioning tool will of course still report the real length. It's just that the viewport length does not corresponds.

Which actually makes sense. For isometric representations at least some axis could get the real length (so yes! Use that if you want e.g. overlay it on a section). For perspective views that is not the case.
