Approximate Curves

Synopsis

obj = SPLINE/APPROX,[{BLANK|DELETE}][,TOLER,t]obj list

Description

Creates a spline which approximates a list of previously defined objects. The spline can be created to a tolerance, or by approximating each curve segment for each object in the list.

NOTE: You can approximate only lines, arcs, splines and conics with splines.

Parameters

Parameter	Description
APPROX	Minor word that indicates that the spline is to be created by approximating a series of existing objects.
BLANK	Minor word that indicates that the objects in the object list are to be blanked when the spline is created.
DELETE	Minor word that indicates that the objects in the object list are to be deleted when the spline is created. NOTE: If neither BLANK or DELETE are specified, the objects in the object list are not modified. Therefore, the spline lies over the objects on the CRT.
TOLER	Minor word that indicates that a tolerance is to be specified to create the spline. If none is specified, the default is the value set in the Unigraphics option Preferences—>Modeling. You can also read and set this tolerance using the GPAs &DISTOL.
t	A numerical value greater than zero which represents the tolerance which is used to calculate the spline. The tolerance is the maximum cylindrical distance between the spline and the original curves at any point.
obj list	A list or array of existing objects which are to be approximated by a spline. The objects must be contiguous.
