Paneling 3d part on the surface from a step file

Hi everyone,
I’m a bit new in Grasshopper world and i need your help and guidance.
I’m trying to create a wavy pattern that will run on a surface that I imported from SolidWorks as a step file.
I was able to produce the wavy pattern and run it on a surface that I built in Rhino.
But when I try to run it on the SolidWorks surface,(step file), nothing works.
From my brief acquaintance with Grasshopper, it shouldn’t be that complicated. Am I wrong? (3.0 MB)
