How to get surface normal in general(on the whole)?
Hi,
Thanks to all of you for your valuable time and efforts putting in helping others.
I want to get the surface normal in general(like showing as *surfacedisplaynormals).However,i can only find hm_getsurfacenormal,which shows normal for a point on surface.
How can i get surface normal value on the whole?
Thank you very much!!!

Surface is curved so every point has a different normal. There is not anything called 'whole normal'
But when i click normal icon or use*surfacedisplaynormals for a surface,a normal will display.What is the meaning of this normal?I think i want to get this value.
That is normal at point that the arrow locates.
The point could be center of the surface.
To get center of surf, I am not sure about hm_getcentroid (pls try)
