The Circle tool converts raster circles to vector circles. Select a raster circle and AutoCAD Raster Design toolset creates vector that matches its geometry.
Depending on the settings you have specified on VTools General tab on the Raster Design Options dialog box, the Circle tool can even remove the underlying raster circle when you exit the command. For more information, see VTools General Tab (AutoCAD Raster Design Options Dialog Box).
There are four methods of defining raster circles:
- One-pick method detects a bitonal raster circle with a single click.
- Center multi-pick method converts any type of raster circle by selecting the center point and any point on the circumference of the circle.
- 2P multi-pick method converts a raster circle by selecting two points to define the diameter of the circle.
- 3P multi-pick method converts a raster circle by selecting three points on the circle.
Once
AutoCAD Raster Design toolset has vectorized a circle, you can:
- Vectorize another circle using any of the four selection methods discussed above.
- Verify or edit the center, radius, or diameter of the circle. You can specify new values by numeric entry or by clicking another circle in the drawing that has an attribute you want to match. This matching operation is particularly useful when you are vectorizing several circles of identical diameter, or a set of concentric circles.
