New Post: Unable to select a shape from shapefile of shpType.POLYGONZ using the Shapefile.SelectShapes method

Hi,

I have the exact same problem with summi in this post:

http://www.mapwindow.org/phorum/read.php?3,13766,13784

I have tried to extend the Extent using maximum range for the Z coordinat:
ShapeExtents.SetBounds(X1, Y1, Double.MinValue, X1, Y1, Double.MaxValue);
But it's still not working...

Is there a solution without have to convert the polygon to 2D?
The requirement is only to select the polygon on mouse click.

Anyway, sample code for collapsing 3D polygons down to 2D will be appreciated also.

Thanks!
