Sweep Along Two Traces

Use it!

(3D only) Used to create a B-spline surface by sweeping one or two section profile curves along two trace curves.

Tool SettingEffect
Method

Sets the number of section profile curves.

  • Sweep One Along Two
    • — one section profile curve.
  • Sweep Two Along Two
    • — two section profile curves.
Scale To Second Trace

If on, the section profile curve is scaled as it sweeps along the two trace curves. If off, the second trace curve simply serves to control orientation. This option is enabled only if Method is set to Sweep One Along Two.

Scale Section Height

If on, the section profile curve is also scaled in the height direction. This option is enabled only if Method is set to Sweep One Along Two and Scale To Second Trace is on.

To sweep a section profile curve(s) along two trace curves
  1. Select the Sweep Along Two Traces tool.

  2. Identify the first trace curve.

  3. Identify the second trace curve.

  4. Identify the first (or only) section profile curve.

  5. If Method is set to Sweep Two Along Two, identify the second section profile curve.

  6. Accept.
    The surface is generated and displayed.

  7. Accept the surface.

    Sweep One Along Two: Identify the first (1) and second (2) trace curves followed by the profile curve (3). Enter a data point (4) to view the surface. Accept/Reject the surface.

    Left: With Scale to Second Trace turned off, the profile curve is swept along the first trace.
    Center: With Scale to Second Trace turned on, the profile (width) is scaled to the second trace, as it is swept along the first trace.
    Right: With Scale Section Height turned on, both the width and the height of the profile are scaled as it is swept along the first trace.

    Sweep Two Along Two: Identify the first (1) and second (2) trace, followed by the first (3) and second (4) profile curves. Enter a data point (5) to view the surface. Accept/Reject the surface.

    The surface is scaled to the second trace as it is swept along the first. At the same time it transitions from the first profile to the second.
