This section describes NURBS curve and surface related modeling
tools, which you can find in the "Tools"
menu of the main window.
A Closed B-Spline
A NURBS Circle
Left: original curve, Right: resulting split curves for t=0.5
Successive Application of Elevate Tool (Order 3 (left), 4 (middle), 5 (right))
Successive Application of Refine Tool
Left: original curve, Right: clamped curve
Left: original curve, Right: a knot has been inserted 1 time at t=0.5

"LazyNotify"
is enabled, updates of the
tesselation that normally occur while dragging the slider will be
deferred until the mouse button is released.
If the "Ok"
button is pressed to close the tesselation tool, all
selected NURBS patch objects will be replaced by their tesselated
counterparts;
if "Cancel"
is used, all NURBS patch objects remain unchanged.
If the check box "SaveToTag"
is activated, closing the tesselation
tool using "Cancel"
will also add a "TP"
tag containing
the currently selected method and parameter value to all selected
NURBS patch objects.
