Use
the Tube Surface tool to create
a variable radius tube surface that uses free curves as a path.
- Choose Surfaces > Tube Surface
- Select a curve
The curve is highlighted in yellow and a blue
radius manipulator appears at the start of the curve.
NoteIf
the Chain Select option is turned
on, curves that are tangent continuous with the selected curve will
also be selected.
- Adjust the radius by dragging the mouse
on the blue circle, or by entering a value on the prompt line.
- Click along the curve to create extra
radius manipulators, if necessary.
- Do any of the following:
- Change the position of a manipulator
by clicking and dragging the small circle at the center.
- Change the radius of a manipulator by
clicking and dragging on the larger circle.
- Press the Recalc button.
A tube surface is produced.
You can keep modifying
or adding radius manipulators then press Recalc again
to modify the tube surface.
This tool maintains construction
history. Modifying the curve will update the tube surface. Selecting
the surface then choosing the tool again lets you modify the radius
manipulators some more.
