Does anyone know how to correct a scale issue on the design layer. I imported some drawings in vectorworks, which the architect said were 1:1 scale. Document settings: Unit millimeters but the object information is showing as 3.975 instead of 3975. Does anyone know how to change it so it is reads 3975? Is it something do with the precision, its showing at 0.001? Thanks in advance. Karen
