Reshapes
a curve so it is tangent or curvature continuous with an object
it touches.
Create tangent continuity
between a curve and a surface
- Choose Curve Edit > Project Tangent ❒.
- Click the curve or surface edge you want
to modify, near the end which intersects the surface.
- Click the surface, near the edge from
which the curve will project.
- Use the tangent/curvature manipulator
to adjust the parameters of the projection, or use the controls
in the control window.
NoteUse the Transform Control option
in the control window to choose whether to create tangent or curvature
continuity.
How do I use the manipulator?
- Click an axis line to set the tangent
direction.
- Click an arc, or the square, or circle
(if available), then drag the mouse left and right to change the
value, or type a number to set the value exactly.
When you are finished
adjusting the curve, click another curve, or choose another tool.
Make a curve tangent to
a curve intersection
- Choose Curve Edit > 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.
An
indicator appears at the intersection.
- Do any of the following:
- Drag the to change the tangent scale.
- Drag the to change the tangent rotation.
- Drag the to change the angle of the
curve to the tangent plane. This will remove tangent continuity.
- Use the controls in the control window.
- When you are finished adjusting the curve,
click another curve, or choose another tool.
NoteConstruction history
is not available when projecting from a curve intersection.
What if...?
The control window is
not open?
If you just choose the Project
tangent tool, the control window does not appear, and
the tool uses the same settings as last time.
To open the control window,
double-click the tool, or choose the option box icon (❒) in the palette menu.
