Both of the designs are composed of four identical segments that may be used to decorate angles/corners. These 3D designs are suitable to be used in some of your more complex 3D projects; you can engrave them on wooden panels with a CNC engraving or routing machine, even make casting molds based on the 3D models, or print them on a 3D laser printer. The given 3D designs are similar to each other - both are symmetrical and made up of swirl lines. 3D models can be easily created in both NURBS 3D CAD and 3D graphics software from designs consisting of swirl lines. We have modeled both of these 3D designs as mesh 3D models, and then converted the models to NURBS 3D surfaces. Both of these 3D models are bas-reliefs that can be scaled to desired dimensions, and by scaling along the Z-axis, desired relief height can be obtained.
