Vectorization tools (VTools) partially automate the process of vectorizing raster entities. Each tool is designed to follow and vectorize a particular raster geometry type.
Vectorization tools include three followers:
- Polyline Follower. Converts raster polylines to AutoCAD polylines.
- Contour Follower. Converts raster contours to AutoCAD contour objects or to polylines with elevation. When a contour is completed, the contour follower prompts you to enter elevation data.
- 3D Polyline Follower. Traces a defined fence or existing vector polyline, stopping at each point where it intersects a raster entity (raster impact point) to prompt for elevation data. The resulting AutoCAD 3D polyline represents the elevation of the raster contours it intersects.
You can use the contour follower to vectorize a contour and the vtext command to convert the text label associated with it.
