Working with survey data, field data, and field codes in Civil 3D involves managing raw survey data, processing it into usable geometry, and using field codes to automate the creation of points, lines, and figures. Here's a comprehensive guide to understanding and using these features.
1. Survey Data in Civil 3D
Survey data refers to the raw measurements and observations collected during field surveys. This data is used to create points, surfaces, and other design elements.
A. Import Survey Data
Open Survey Tab:
Go to the Toolspace and click the Survey Tab.
Create or Open a Survey Database:
Right-click Survey Databases > New Local Survey Database.
Name and save the database.
Import Data:
Right-click the survey database and select Import Survey Data.
Follow the wizard to import data from:
Field Books (FBK)
Text files (e.g., CSV, TXT)
LandXML files
Map the file format to the appropriate data type (e.g., points, linework).
B. Manage Survey Points
Survey Points:
Points are the foundational elements derived from survey data.
You can edit, group, or classify points in the Survey Tab.
Description Keys:
Description keys automatically assign styles and labels to points based on their descriptions.
2. Field Data in Civil 3D
Field data consists of measurements, observations, and codes collected during a survey. It is typically stored in a Field Book (FBK) or text file.
A. Importing Field Data
Supported Formats:
FBK files: These include detailed survey observations (e.g., angles, distances).
CSV/TXT files: Contain point data (e.g., Northing, Easting, Elevation, Description).
Process Field Book Files:
Use the Survey Tab to import FBK files.
Adjust settings for instrument setups, traverse computations, and more.
B. Field Data Processing
Observation Editing:
Edit raw observations like distances, angles, and station setup.
Linework Creation:
Process raw data to generate linework (e.g., boundaries, utilities).
3. Field Codes in Civil 3D
Field codes (also known as linework codes) are used during the survey to identify points, features, and connections. They automate the creation of figures and linework.
A. Linework Code Sets
Access Linework Code Sets:
In the Survey Tab, right-click the survey database and select Edit Linework Code Set.
Define codes for starting, continuing, or ending lines (e.g., B for Begin, C for Continue, E for End).
Common Field Codes:
Codes for points (e.g., "IP" for Iron Pin).
Codes for figures (e.g., "CL" for Centerline, "EDGE" for Edge of Pavement).
B. Creating Survey Figures with Field Codes
Configure Figures:
Assign codes to automatically generate lines and polygons.
Use Control Codes to specify actions like curves, joins, or skips.
Process Field Codes:
After importing data, process linework using the field codes to generate survey figures.
4. Using Survey Data in Civil 3D
A. Generate Points
Points are automatically created based on imported data.
Assign styles, labels, and description keys for visualization.
