Transcript
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.
