Draw Freehand Sketches
Sketching is useful for creating irregular boundaries or for tracing with a
digitizer.
Draw 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.
Before 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
You 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.
When 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.
With some digitizers, you cannot select the menus while Tablet mode is on.
See your digitizer documentation for details.
