Vectorization tools (VTools) can convert geometry and text in a bitonal raster image.

With vectorization tools, you can:

■

Use a one-pick method to accurately trace raster entities you select.

■

Use a follower method to trace complex geometry, such as contours.

■

Verify and adjust a vector entity's dimensions as it is drawn to make it more precise.

■

Remove a raster entity automatically as you trace it.

In many cases, a vectorization command can convert a raster entity to vector with a single
click. You can also define the raster entity by clicking two or more points on the image. Once
a vectorization command is initiated, you can continue to vectorize additional raster entities
using either selection method.

There are seven primary vectorization tools for converting raster entities to corresponding
AutoCAD objects:

■

Line tool

■

Polyline tool

■

Rectangle tool

■

Circle tool

■

Arc tool

■

Text tool and Multiline Text tool

Follower VTools provide a semi-automatic method of tracing the raster polylines you want
to vectorize. For example, the contour follower tool traces a selected contour line until it
meets a decision point such as an endpoint or a contour label. At each decision point, you
