Draw Splines
AutoCAD uses a particular type of spline known as a nonuniform rational B-
spline (NURBS) curve. A NURBS curve produces a smooth curve between
control points. Splines are useful for creating irregularly shaped curves, for
example, drawing contour lines for geographic information system (GIS)
applications or automobile designs.
You create splines by specifying points. You can close the spline so that the
start and endpoints are coincident and tangent.
Tolerance describes how closely the spline fits the set of fit points you specify.
The lower the tolerance, the more closely the spline fits the points. At zero
tolerance, the spline passes through the points. You can change the spline-
fitting tolerance while drawing the spline to see the effect.
