Set scale on drawing
By selecting ‘set the scale on the drawing’ you pick two points, which define a specific length, on the drawing and the window below appears on the screen.
Enter the length you have marked on the drawing, click ΟΚ, and the scale appears on the drawing. Click the Update and close button to save the new scale. If you select ‘Reset scale’ from the drop-down menu, then the scale is set to its default value (1:1).
