I'm trying to extrude a simple square shape along a curve, with the view to making a set of steps go around a corner.
Extruding a circle works perfectly, but a square shape seems to extrude along the Y axis instead of the X and is therefore just a flat shape.
Steps - Created cube shape
Selected 1 face and duplicated it
Separated the face so it is a single object
Alt+C - converted mesh to curve
Gone to path object panel > Geometry and selected the 'Bevel Object' to be the square
The Extrusion is a flattened mesh.
Doing the exact same steps with a cylinder works just fine.

Many thanks in advance.
