Can you utilize an equation for a mathematical surface?

Specifically, looking to see if we can utilize Feature Script as a way to parame-tize an equation for a mathematical surface, ie. something like a gyroid; Either by using said "surface" equation directly in Feature Script, or by importing a pre-built Math. surface OBJ file from another source, for example, as output from Mathmod....and subsequently imported into Onshape Part Studio tab....

Thanks!

Yes, it's totally possible to do this in FeatureScript. Check out this custom feature for a parametric surface:  https://cad.onshape.com/documents/57a62df8e4b03de4c9fcf154/w/f6d71f3d862b522902efcd68/e/ece65382fcd820281a9ee704

Thanks, I'll take a look!

The parametric surface FS is handy if you have a surface that can be described as a 1-to-1 function f(x,y). However, if you have an analytic, cyclic closed surface like a twisting torus, it would probably be easier to use the Parametric Curve FS to make an analytic curve that you can then use as a sweep path. However, I think you might be out of luck modeling a true mathematical gyroid since it's neither path-based nor 1-1 in any coordinate system.
