Sketching is useful
for creating irregular boundaries or for tracing with a digitizer.
freehand sketches with the SKETCH command. Freehand
sketches comprise many line segments that are converted into a line,
polyline, or spline.
For Splines, you can
determine how closely the spline’s curve fits to the freehand sketch.
For any sketch type,
set the minimum length (increment) of the line segments. Small line
segments allow greater accuracy, but they can greatly increase the
drawing file size.
sketching, check the CELTYPE system variable
to make sure the current linetype is BYLAYER. When you sketch with
dot or dash linetypes, smaller line segments can become invisible.
Sketch in Tablet Mode
use Tablet mode with a digitizer. Sketching in Tablet mode is useful
for such things as tracing map outlines from paper directly into
a drawing. You cannot turn off
Tablet mode while sketching.
Tablet mode is on, you can configure the program to map the paper drawing's
coordinate system directly into the world coordinate system. Thus, there
is a direct correlation between the coordinates where screen crosshairs appear,
the coordinates on the tablet, and the coordinates in the original paper
drawing. After configuring the program to match the coordinates
of the paper drawing, you may find that the area shown on the screen
is not the area you need. To avoid this problem, use ZOOM to display the
entire work area before you start to sketch.
To draw freehand sketches
At the Command prompt, enter sketch and
Press Enter again to accept the last
saved type, increment, and tolerance values.
