Art Nouveau 3D designs

Art Nouveau 3D designs On this page you can download two 3D designs in the Art Nouveau style which are intended to decorate square surface areas. Both of the designs are composed of  four identical segments that may be used to decorate angles/corners. 
These 3D designs have been modeled in Blender software and then the resulting polygonal mesh models have been converted into a NURBS model with Rhino software.
For those who are dealing with polygonal mesh software, .obj file format has been made available, and for those working with 3D CAD software, the 3D designs are downloadable in step format.
