Dimension does not work on preselected entity, reason for this?

Dimension does not work on preselected entity like other constraints do in a sketch.

If I select a line and then press "vertical" magic happens.
If I select a line and then press "dimension" the line deselects, I have to click it again to make a dimension.

I am sure there is a reason for this I just can't figure it out myself.

    Dimension tool behavior is similar to other mcad I've used (Geomagic Design) in a way that it figures out what I'm trying to dimension (ie. smart dimension). But Geomagic allows also preselection and I haven't had any issues with that.

    I think possibility to preselect things for dimension tool would make constraining tools much more consistent. It is always annoying if one needs to memorize workflows that are not consistent with similar tools, in this case other constraints.

    Good point. I take back what I said, because I agree that consistency is vitally important.
    The lack is particularly evident in Onshape drawings at present.

    Interface consistency with the modeller is minimal, and the resulting burden of cognitive stress is noticeable.
