I recently made a quick script commonly used in 3D printed jewerly design for fun.

The function below will take a surface and parameters to get iso curves out of it.

To get the result you want, the input surface will have to be carefully modeled with consideration of direction of U and V on the surface.

As you can see in the script below, output curves will not exactly follow input surfaces as those are only approximated by creating curves from points on the surface.

This mesh model can be easily modeled with 3DS wave modifier.

Here’s a sample code to achieve the same result with Rhino SDK.

The sample is taking three points of origin of sine waves.

In the age of digital design, designers are destined to face the process of rationalizing the form after a lengthy foreplay of form making in order to fabricate it into an actual product. Ironically, some designers/architects these days fully exploit the capability of freeform design to irrational extreme and put another effort and cost in rationalizing the form therewith. Many of these rationalization processes deal with panelizing the freeform surface such as approximating designed surfa[……]

All the stiffness of modeling environment and constraints in BIM modeling process sometimes give you frustration and less freedom in modeling but in the end it actually results more accurate, parametric (and therefore flexible) model. So the issue should be when to implement BIM after concept design stage.
