Re: Why a NURBS surface always automatically rotates after being generated
Attach a zip with your GiD model to do some meshing tests. Dear escolano, I am sorry for causing your confusion by my complicate description. That will be much clear with data and files. I attached two gid files: the file “1volm“ is the one I showed and described. It always crashed when...

Re: Why a NURBS surface always automatically rotates after being generated
Thank you very much for the explanation about the NURBS surface, escolano. Consider the limitation of NURBs surface, I decided to move to the way for making the surfaces by lines and dots. With giving up the resolution of topography, the geometry can still represent some rough characteristics. https...

Re: Why a NURBS surface always automatically rotates after being generated
Dear escolano, Thank you very much for the detailed explanation about how the GiD create NURBS surface. Now I have a clearer view. About the interesting question that how did I make that mesh which can solve all of my questions... Well, I tried to use a smaller dot cloud, from a square shape to a re...

Re: Why a NURBS surface always automatically rotates after being generated
Dear escolano, Thank you very much for your explanation. a) The second figure which I attached in my first post was also created by GiD in couple of months ago (with a correct fitting between NURBS surface and dot data cloud), then I wander why the NURBS surface became different in this time. As you...

Why a NURBS surface always automatically rotates after being generated
Dear All, I have a question about generating a NURBS surface: That the generated NURBS surface (by points) always be rotated automatically. For example: 1) A set of xyz data was imported for representing the topography. 2) Then I used geometry->create->NURBS surface->by points to select all the dots...
