digitizing two polygons

[Sung-Won Choi]

Hello!

I have some questions!.

for example, I have two polygons having a common boundary,
so I'm gonna digitizing these in Autocad R13.
As far as I know, I should digitize the common boundary twice to make
two polygons.

Is it true?

if not, can I get two polygons by digitizing the common boudary just
once?

Thank you in advance!
