The picture shows a 3D model of a simple ornamental design, which has been modeled in NURBS 3D CAD software and made available to you for free.

This one and similar 3D design patterns are very easy to model in any 3D CAD software. If, according to this 3D model, we were to imagine the 2D design on the basis of which it had been modeled, it would consist of curved decorative lines (scroll lines, swirl lines) with variable thickness. Such lines are ideal to make a relief because they consist of two lines that can be used as guiding curves for the Sweep command in some 3D CAD software. All that is left is to draw the cross sections you want and arrange them normally with respect to the guiding curves, and then form the relief surface with the Sweep command. Of course, if it is necessary to model more of such surfaces and there are places where they intersect (pass through each other), the surfaces need to be mutually trimmed, and the resulting unnecessary parts need to be deleted. This way you can quickly draw relief 3D models not only of such simple designs, but also of much more complex ones.

So, if you like challenges, download some similar 2D design from the “Free Patterns” category of our site and try to model it in the 3D CAD software that you are using.

This free 3D design is symmetric with respect to the y axis and intended to decorate a rectangular surface area. This is a very simple 3D model drawn while mastering Rhino 3D software.
