As an aside, the way I work around no dimension setting on other software, and something that works well here, is to set up a drawing space big enough to handle your drawing at an easy scale to manage in your head (e.g. .1" = 1" or 1" = 1' or that metric thing ) then after the drawing is done, scale the whole thing to something that fits on the output medium you need to print on. Much faster than getting out the calculator every you need a new measurement. (The project I mentioned above was an existing document that I brought over from CorelDraw to use in a document, so the page was already done and I didn't want to tear it all apart.) It seems that max sheet size is 71.111ft x 71.111ft (2167.47cm) which gives you a lot of room to get to an easy-to-convert scale.

Allow me to second that emotion. Setting scale units is a key feature in drawing anything that doesn't live on a piece of paper. Even large scale printing (billboards, posters, wall art, vehicle wraps) is difficult to do without some reference to measurements in meatspace. I'm just getting started and loving the software as a whole (leaving Corel Suite after 18 years) but I instantly had to pull out my calculator to dimension a floor plan I'm working on for an event venue. Add my vote in favor of adding the ability to edit the scale units on dimension tools in Designer!
