Tips
•
The Lo ck Selection Set button is useful
when you transform NURBS point sub-objects.
You can make a selection in one viewport, click
Lock Selection Set (or press the SPACEBAR),
andthentransformtheselectioninadifferent
viewport.
• When you move point sub-objects, move them
as systematically as po ssible to avoid "getting
lost."
• On surfaces, avoid moving points so they cross
over or under adjacent points. This can create
odd-looking warps or overlaps in the surface.

• Hold down SHIFT while you transform the
point.
This works only for points that lie on curves
or sur faces, independent

sub-objects, and curve point (page 1–1222) or
surface point (page 1–1223) sub-objects that

To use the k eyboard to select point sub-objects:

key and the arrow keys. The arrows traverse the
sub-objects in the order they were c reated. To do
so, follow these steps:
1. Tur n on t he Ke y bo a rd Shor tcut
Override Toggle.
2. Click or drag to select points.
3. Hold down CTRL and use the arrow keys to
move among the point sub-objects.
For points on curves, the arrow keys tr averse
the point selection along the length of the
curve. The arrow keys don’t move between
curve sub-objects.
Forpointsonsurfaces,theleftandrightarrow
keys traverse the U dimension of a surface,
while the up and down arrow keys traverse the
V dimension of the surface. The arrow keys
don’t move between surface sub-objects.
