Hi, I am not very strong in maths, so sorry if these sounds simple. If I have a 3D geometry of a pipe which has its surface defined by triangles (such as that in Computational Fluid Dynamics or Finite Element Analysis) and I have the coordinate points for all the triangles, how can I represent the 3D object into a 2D plane. This would be like slicing the pipe through its centre and then unwrapping it into a flat piece. Would I use some kind of mapping? Is this achievable? Thanks!
