Hi Wayne, In recent versions of Punch (V10 and V12), each time your select a 3D workshop object in the plan,a cabinet or a chair, etc the dimensions and other info will appear in the Properties bar, at the right of the screen. From this bar you can change the dimensions, angle, etc In addition, for all the versions, each time you select a 3D workshop object, the name and dimensions will appear in the Status Bar (bottom left of the screen) For Punch versions= V8 and older, you must open the objects with the 3D Workshop in order to change the dimensions. Or with the Cabinet Wizard for cabinets developed and saved with this Power Tool Patricia
