We whipped up a hotfix for our latest release. Sad to say, a bug managed to slip in: The dimensions of objects measured in architectural units were different in the drawing sheet than in the design space. With the newest 4.0.1 update, they should be in working order.
But before you go back to the drawing board, remember that the dimensions in the design space are rounded to 3 decimal places, while dimensions in the drawing sheet are rounded to 2 decimal places. So, that means 3.847 inches in the design space is shown as 3.85 inches in the drawing sheet.
