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