Zebra surface diagnosis for XSi

[bullit]

Hello i am new to XSi, i am a designer, modeller with some profess. work also in compositing(3D integration in video) i will use it for model/vizualisations of my concept designs .

i am looking for a shader that can help me model better surfaces/polygons . Like it exists in Rhino or Alias StudioTools, ICEMsurf and others professional applications.

here can be seen the zebra stripe in solidworks

I managed to find a temporary solution. Later when i will know the software better, how to make a shader with simple commands to make a variations. maybe a control panel. Still need to render...

It's a simple material with an Incidence node and a checkerboard shader/image (correct terminology?), this one changed in a way to see only horizontal or vertical lines (that way i can achieve a zebra).
