I have been writing some code that maintains the Z dimension for vector layers. When I create a layer from QGIS points whether it is a point or line layer and I create the points with QgsPoint(x, y, altitude), I can do this without using PointZ or LineStringZ layers and it maintains the Z axis.
What is the purpose of PointZ, LineStringZ, and PolygonZ? Is there a reason I should be using them when Point, LineString, and Polygon seem to work the same? Is there a reason I should not use the Z versions? Thanks, Calvin
