Reshape a curve or surface manually
Editing NURBS
Align surface edges
Align a curve with a curve
or surface
Make
a curve tangent or curvature continuous with a surface
- Select the surface and then the curve.
- Select
Edit Curves > Project Tangent > .
- Set Construction to Tangent or Curvature.
- Click Project.
Select the project tangent
node and click the Show Manipulator tool to manipulate
curvature scale, tangent scale, or tangent rotation.
To make a curve tangent or curvature
continuous with a curve intersection
- Choose
Edit Curves > Project Tangent > .
- Click the curve or surface edge you want
to modify, near the end which intersects the surface.
- Click two intersecting curves that define
a plane.
To make a curve tangent or curvature continuous
with another curve
- Make sure the endpoint of the curve you
want to make tangent intersects the curves that define the plane.
- Select the curve you want to reshape
first, then select the other curves.
The projected tangent
is based on the key curve (the curve you select last, highlighted
in green).
- Select
Edit Curves > Project Tangent > .
- Set Construction to Tangent or Curvature.
- Click Project.
Edit a project tangent action
- Select the project tangent node and click
the Show Manipulator tool to manipulate
curvature scale, tangent scale, or tangent rotation.
To align the ends of two
curves
- Select the points on the curves (or isoparms)
where you want to align the curves.
- Select
Edit Curves > Align Curves.
TipWhen construction
history is on, you can select the align node and use the Show
Manipulator tool to edit the tangent scale and curve
points.
What if...?
I can’t project tangents at both ends
of a curve?
- The project tangent action “takes over”
a few CVs at the end of the curve to maintain continuity. If there
aren’t enough interior CVs to avoid overlap, you can’t use project
tangent at both ends. Try inserting edit points to increase the
number of CVs on the curve.
