• Corridor design is only one step in final surface creation
• Other gratings or surface adjustments may be needed for final surface
• Refinement surface is the final surface, combination of all definitions, pasted together
• Refinement surfaces source of data in section views, plans/profile sheets, etc.

 

• One refinement surface for each final surface:
  • Top, Datum
• No matter how divided up the project definition
  • ALL Top surfaces in Rfnt-Top
  • ALL Datum surfaces in Rfnt-Datum
• Other gradings or adding breaklines

 

• Pasting into final refinement
  • Last surface pasted takes precedence where there is conflict
  • Plan the order to be pasted
  • Top and Datum surfaces are defined to daylight, so there are large areas already exactly the same
