How to scale a model in paper space so that I can dimension it there?

I am used to scale my drawing to say 1/4" scale right inside a viewport. Then I use "dimlfac" to set the dimmensioning to 1/4" scale and I do my dimensioning in paper space. If I can't do it in DraftSight that way, can someone help me with the way to dimensioning in scale?

Thanks,
