Maybe the easiest way would be to create these segments as an array of
separate polyline objects, and then combine them into one when you have
finished.

I have a MapBasic 4.5 command:
Alter Object TempPolyLine Node Add Position PolylineSections,
ObjectInfo(TempPolyLine, OBJ_INFO_NPNTS) + 1 (PointLong, PointLat)
TempPolyLine is my polyline which was originally created with:
Create Pline Into Variable TempPolyLine 0
PolylineSections is a "SmallInt value (one or larger), identifying one
section from a
polyline object".
ObjectInfo(TempPolyLine, OBJ_INFO_NPNTS) + 1 is of course the number
of
existing nodes + 1, to refer to my new node number that I am about to
create.
PointLat & PointLong are my Latitude & Longitude of the node I want to
create.
I am reading in polylines from another file format (Garmin .mp "polish"
format). These
polylines have multiple sections, so I want to create the MapInfo
polylines with the same
multiple sections.
All works well while PolylineSections is 1, but as soon as I try to add
the first node after
changing PolylineSections to 2, I get a MapBasic error:
"Alter Object Node Add failure"
Am I trying to do this the wrong way? Can I just keep adding points &
the new section
will be created automatically, or am I missing some command to inform
MapBasic that I
am adding in a new section?
Thanks,
Dave
