sdbox ⮕ Dim by layer

ZDLAYT: Add Texts for side lengths for all objects on the same Layer.
Pick on screen an object from each Layer that you wish to dimension.
Side length dimensions for Lines, Plines and total length for Splines and Arcs will then be automatically added to any objects that have the same Layer as the ones you selected.
In the tab of the ZDDAT command you can set decimals, multiplier, prefix and suffix. You can also set a minimum value, where dimensions smaller than this value are highlighted in the Drawing and transferred to Layer z_Dim-Error.
