Both working marks and the roughness symbols indicate the surface processing degree (or state).

Even though the surface working marks are always less used, it was considered useful to include them in the package with the surface roughness symbols.

For the first commands are used symbols pre-set in as many drawings, saved in the Top work directory, while for the roughness the settings are defined each time.

All working marks described, if we are in the model space (TILEMODE=1), follow the scale set with the command Top_Imp_Scala, if we are in the paper space (TILEMODE=0), the scale is set on default (1:1).
