Hi L-sters!
you will say I am splitting hair, but I came across a strange
feature in MI.
Because I need only linear object in a table for thematic purpose, I convert
point objects to zero length line objects using : Update <my table> set obj
= CreateLine(CentroidX(obj), CentroidY(obj), CentroidX(obj),
CentroidY(obj)). I was not sure that it was going to work. It did like I
expect it to. But it does not work with zero length polylines. My goal was
to override the style with a thick line that was going to mimic a circular
symbol. Until now, everything is fine. It gets strange when I set a clipping
region. All my zero length objects are no longer visible, inside or outside
the clipping region. They are still selectable, I can see the highlight but
cannot see them when not selected. I set the clipping region to OFF, and
they are visible again. I suppose it has to do with the way objects are
processed when they are clipped. It's a very singular object, a line with
the start and end nodes at the same coordinate.
Someone has a piece of explanation to offer?
