Creating Swept Surfaces Using a Conical Profile

You can create swept surfaces that use an implicit conical profile, such as parabolas, hyperbolas or ellipses.

These swept surfaces are created based on guide curves and tangency directions..Either the supporting elements or a curve giving the direction, create the tangency direction.

This task shows you how to:

Before you begin: Create a 3D shape containing sketches and curves.

Two guide curves

You can create swept surfaces that use an implicit conical profile by defining two guide curves.

  1. From the Surface section of the action bar, click Sweep .
    The Swept Surface Definition dialog box appears.
  2. Click the Conic icon in the Subtype list and select Two guide curves.
  3. Select two guide curves and their tangency supports, indicating an angle value in relation to the support, if required
  4. In the Parameter box, enter the parameter value or use the arrows to change the value.

    It is a ratio ranging from 0 to 1 (excluded), and is used to define a passing point as .

  5. Optional: In the Spine box, select a spine to specify a spine different from the first guide curve or center curve.

    If the plane normal to the spine intersects one of the guiding curves at different points, it is advised to use the closest point to the spine point for coupling.

  6. Click OK to create the swept surface.

    The surface (identified as Sweep.xxx) is added to the tree.



Three guide curves

You can create swept surfaces that use an implicit conical profile by defining three guide curves.

  1. Click Sweep .
    The Swept Surface Definition dialog box appears.
  2. Click the Conic icon and in the Subtype list, select Three guide curves.
  3. Select three guide curves, and the tangency supports for the first and last guides. If required, indicate an angle in relation to the support.
  4. Optional: In the Spine box, select a spine to specify a spine different from the first guide curve or center curve.

    If the plane normal to the spine intersects one of the guiding curves at different points, it is advised to use the closest point to the spine point for coupling

  5. Click OK to create the swept surface.
    The surface (identified as Sweep.xxx) is added to the tree.

Four guide curves

You can create swept surfaces that use an implicit conical profile by defining four guide curves.

  1. Click Sweep .
    The Swept Surface Definition dialog box appears.
  2. Click the Conic icon and in the Subtype list, select Four guide curves.
  3. Select four guide curves and the tangency support for the first guide.
    If required, indicate an angle in relation to the support.
  4. Optional: In the Spine box, select a spine to specify a spine different from the first guide curve or center curve.

    If the plane normal to the spine intersects one of the guiding curves at different points, it is advised to use the closest point to the spine point for coupling.

  5. Click OK to create the swept surface.
    The surface (identified as Sweep.xxx) is added to the tree.
