Understanding some key factors behind stream mode digitizing will help you understand how to use it more effectively.
Digitizing under the windows extensions (ARCEDITW) works slightly differently than under DOS (ARCEDIT). ARCEDIT displays the line constantly during digitizing, where as ARCEDITW does not. This is because drawing all the little line segments during digitizing can slow down the process by a factor of 2. You can, however, display the line at any point. This will be discussed in more detail later.
Using a compatability box in Windows (3.x, 95, or NT) is not the same as running in DOS. You should not run ARCEDIT or DIGTEST in a DOS compatability box, nor at the ARC prompt under Windows (3.x, 95, or NT). Otherwise you will get lots of beeps and lost digitized points. Misunderstanding this may lead you to believe PC ARC/INFO is digitizing poorly.
Before you can do stream mode digitizing, you must set up the digitizer format file to enable stream mode digitizing. Some of digitizing format files are not set up for stream mode; thus, it can be misconstrued as PC ARC/INFO not being capable of stream mode digitizing.
If the digitizer format file is not set up for stream mode, you can do only point mode digitizing. ARCEDIT and ARCEDITW operate slightly differently:
In ARCEDIT and ARCEDITW, you can track the cursor by pressing
the "0" key or the key that sends a "0".
In ARCEDIT, pressing the "1" key draws each line segment on the screen.
In ARCEDITW, a line segment is not drawn until either a "0" or "2" key is
pressed. In other words, you can see what the line looks like by pressing
the "0" or ending the line with a "2" key.
ARCEDIT constantly tracks the cursor.
ARCEDITW does not. You need to press the "0" key.
In ARCEDIT, as you press the "1" key, each line segment is drawn on the screen.
In ARCEDITW the line segments are not drawn until either a "0" or "2" key is pressed.
In other words, you can see what the line looks like by pressing the "0" or ending
the line with a "2" key.
Both ARCEDIT and ARCEDITW track the cursor.
ARCEDIT draws the each line segment immediately as it is added a line.
ARCEDITW draws the line segment(s) when you release the "1" key or press the "0" or "2" key.
