Wow thank you rajaa for the prompt reply. I’m still getting used to the panelling tools and getting familiar with the functions it can perform. It is taking me a while to figure out how to create good grids out of more irregular surfaces.
Also, I just watched one of your webinars. It was really helpful. The key thing is really to create the single grid for tessellation.
I have another question. How to you make sure the resulting surfaces are properly joined and closed to form a closed polysurface? Even when I tried to use ptpanel3dcustom and defining the two bounding surfaces, the surfaces do not join up.
