• Engineering 1182 Solid. Works: Adding Dimensions, Center Marks and Center Lines Dimensions can be added using the “Smart Dimension” feature Note that sometimes the Isometric needs to be re-scaled to allow adequate drawing space which requires a NOTE. Notes can be added to reduce the number of dimensions by stating symmetry or identifying fillet radii Rev: 2014 -07 -13 - RCB Dimensioning in Solid. Works 7
