Description
Allows the user to fair a current curve, using one of two methods.
The default method is based upon the work of Eck and Hadenfeld and has been made available due to the participation in the FAIRSHAPE project.
By using the /PSK optional qualifier a method developed at the National Technical University of Athens by Pigounakis, Sapids and Kaklis is employed. This method ensures the curves are constructed so that their curvature and torsion plots are as smooth as possible.
By using the /X, /Y or /Z options with the /LOWER and /UPPER options, a portion of the curve can be faired.
The cursor option allows the user to interactively select the portion of the curve to fair.
By selecting the /INTERACTIVE option, the Patch and Curve Editor is opened with those curves marked for editing/boundaries by the MODIFY command. By adding the /BOUNDARY qualifier, curves used as patch boundaries for an existing surface model will also be marked for editing/boundaries.
Adding the /CLEAR qualifier will clear all previously marked curves.
Specifying the /DELETE qualifier will delete all data associated with the selection.
Specifying the /PREVIOUS qualifier will edit the previous selection.
Specifying a name will cause that named selection to be edited.
