Vectorization tools

00:03

Vectorization is the process of converting raster data into standard AutoCAD vector entities.

00:10

One way of performing this conversion in bitonal images is to use primitives.

00:15

AutoCAD Raster Design includes vectorization tools that allow you to define primitives for multiple raster entities,

00:23

including lines, rectangles, circles, and arcs.

00:26

During the creation process, you are prompted to set and confirm the required parameters,

00:32

and the command line displays validation tools for correcting linework values.

00:38

The first example converts a raster line to a vector line.

00:42

On the ribbon, Raster Tools tab, Vectorize and Recognize Text panel, expand the Primitives drop-down and select Line.

00:50

On the raster image, zoom in to select the entity you want to convert.

00:56

In this case, click near the beginning of the line segment at the lower-left corner of the rectangle.

01:01

The endpoint nearest the point you select is considered the start point glyph.

01:06

The command line displays data for the selected line, such as angle and length.

01:11

For this example, enter a new line length to override the existing one.

01:16

In the length dialog, type 18.7, and then press ENTER to confirm the new length.

01:22

Press ENTER again to complete the line conversion from raster data to a slightly longer vector line.

01:28

Next, convert a circle.

01:31

Expand the Primitives drop-down and this time, choose Circle.

01:35

In the image, move the cursor to the small circle in the middle of the drawing.

01:41

Currently, the dimension of the circle is defined by the radius.

01:45

To change this value to diameter, type D, and then press ENTER.

01:50

Type a value of 3.5 for the diameter.

01:54

Press ENTER to confirm the new diameter, and then press ENTER again to accept the vector data for the circle.

02:00

The raster data has now been replaced for both the line and the circle.
