Fit on Cloud
This command is used to fit a CAD Surface on a point cloud.
Fitting means that control points are moved in order to best fit the cloud.
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 cloud having many different "curvature" areas.
Select the CAD surface(s) to fit and the cloud you want to use.
You can select one or several surfaces before launching the command
Note
The surface must be "close to" the cloud in order to have a good fitting.
Some surfaces can't be fitted on cloud:
The restricted surfaces
Closed surface (such as torus, cylinder, sphere)

Note
In this command, the cloud is not modified, only the surface is modified.
Note
If possible, choose the Fit on Mesh command because the result will be better and faster as:
we use the normal vector of the mesh to fit the surface,
the mesh is most often less noisy than a cloud.
Note
In some cases, the algorithm may fail due to overconstrained fitting. Try to disable Constraint borders option.
