Fit on Mesh

This command is used to fit a CAD surface on a mesh. The surface is moved in order to adjust the face (elementary surface) on the mesh (the mesh is not modified).

Select the surface to fit and the mesh to use for the surface modification. You can select one or several surfaces before launching the command.

  1. Check Constraint borders if you want to not modify any edges of the input surfaces. Else, you allow modifying all edges.

  2. Click Preview if you want to see the result.

  3. You can see the deformation of the face inside the 3D scene. You can also see the Maximum distance and Standard deviation between the face and the mesh.

  4. Click OK to validate and exit the command, Cancel to retrieve the original surface.

Notes

  • The surface must be "close to" the mesh in order to have a good fitting.

  • The fitting is also dependent of the control point number: if you have 3 controls points along U and V direction, you cannot correctly fit your surface on a mesh having many different curvature areas.

  • If the surface is bigger than the mesh, it's sometimes better to use Fit on Cloud: control points that have no projection on the mesh will be moved better.

  • Some surfaces can't be fitted on meshes: the restricted surfaces, the closed surfaces (such as torus, cylinder, sphere).

  • In some cases, the algorithm may fail due to overconstrained fitting. Try to disable Constraint borders option.
