Replacement for ptOffsetPoints in Rhino 6

I am trying to create custom 3D panels in version 6, but can’t seem to find a replacement for ptOffsetPoints. In the meantime, I am using an offset surface and running ptGridSurfaceDomainNumber on that for a second group. Is there a replacement for ptOffsetPoints?

Are you using Mac?
Also, are you running PT in Rhino or Grasshopper?
