Due to the Description Key Set not being dynamic in Civil3D, the points can get out of synchronisation with respect to layers and scaling of symbols.
Selecting this command causes Stringer to scan all of the points in the drawing from the field Survey and validate their information against the Description Key Set/Stringer Settings codes you have set up for your firm.
This form will then display
If you expand out the code showing, you will be able to:
See all the codes that AREN"T in your Description Key Set (DKS)
Expand out the + icon and you will see all the points for those codes not being in the DKS
Click on the point number and it will zoom to that point in the drawing (it will show in the direct centre of the drawing space)
Click on the double arrows to the right and it will zoom in/out to that point even further
Its a modeless form so you can click in the drawing and zoom around again and then go and fix the codes up in the DKS
