Drawings 'n dimensions ...

HI,
I'm a bit confused about the dimensions in a drawing.
I initially had a block of 30x60 mm in the Part studio (as marked in the red rectangle).
After setting up the dimensions in the drawing I'm a bit confused about the weird numbers on the other  3 views...

    Dimensions in Onshape drawings are measuring 2D projections of the object as it sits on the paper, rather than the "true" dimension of the 3D object.

    So you will not be able to have dimensions on your ISO view, because it will only be a "Point-to-Point" dimension as if you printed out the paper and measured those points with a caliper.

    @ella_meunier,

    The weird dimensions appear with entities that are not parallel to the drawing sheet. What you are doing is against the 'drawing rules' (of Onshape).

    Ok, understand.
    And how can I fix it?

    When will we be able to make correct 3d (ISO projection or other) dimensions
