Cannot create points in 3d/ with three coordinates

[avohns]

When trying to create a point in the 3d-view, ['A',vector(1,2,3)] does not seem to work as intendes, it seems to only pass the x- and y-coordinate, z-coordinate will always be zero, even when using redefinitions like ['A: B'], where B=(1,2,3) still results in A=(1,2,0).
