I used a map of Canada which comes with MapInfo (very small scale) as a basemap
and overlaid a line feature in which part of the line is supposed to run along
the border of BC and Yukon, I used Equidistant Conic (North America) as the
projection.  But I noticed the line feature did not match or follow the
provincial boundary line very well (line ran south of the border).  To make a
long story short I ended up importing the MapInfo basemap in ArcView and also
the feature line and to my surprise the line and border matched up nicely. I
couldn't figure out why it matched up well in ArcView but not in MapInfo , then
I noticed that in MapInfo the border line that runs between BC and Yukon only
had a two nodes with 630 mi between them and for some reason when I import this
map in ArcView several nodes were added to that line which help in displaying
that line in the Equidistant Conic projection I was using. Therefore I edited
the basemap in MapInfo and added a few more nodes and the lines matched up
nicely when projected in the Conic projection in MapInfo. My question is , are
nodes always added to polygon or line features when converting from MapInfo to
ERSI shape file?

TIA
