Hi everyone!
I want to know about the following parameters and how it affects in the geometry: 1. Curve Chord Tolerance 2. Curve Chord Angle 3. Surface Plane Tolerance 4. Surface Plane Angle 5. Minimum Facet Width 6. Maximum Facet Width 7. Curve Chord Max I'll appreciate your help, it's for my postgraduate program. |

Are you meshing with CAD projection? If so, none of these values mean anything as long as your meshing pipeline retains CAD till the meshing operation. They are only used then for visualization purposes.
If you are not meshing with CAD projection or use an operation that does not respect the CAD definition, then these matter. 1-2 affect how the surface is tessellated when curvature occurs 3-4 affect how the surface is tessellated when there's no curvature or little of it 5-6 control the minimum and maximum edge lengths for a triangle 7 I believe controls the maximum size on a curve, but I'm not entirely sure. |

Hi, it's correct, I'm meshing with cad projection. Thank you for your answer.
