Description Keys: Field to Civil 3D
Description keys bridge the gap between the field and the office. The Description Key Set is a listing of field descriptions and how they should look and behave once they are imported into Civil 3D.
For example, a surveyor may code in BM to indicate a benchmark. When the file is imported into Civil 3D either through the Survey database (as we examined in Chapter 2) or by import from a text file (as you did earlier in this chapter), it will be checked against the description key set. If BM exists in the list as it is in Figure 3-30, then styles, format, layer, and several other parameters are set.
