Creating Projection Curves

You can create geometry by projecting one or more elements onto a face or plane. The projection can be normal to the face or along a direction.

Before you begin:
  • Create a surface.
  • Create a sketch entity to project.
  1. From the Surfaces section of the action bar, click Projection Curve .

    Tip: In the top menu of the dialog box, you can switch between Projection Curve , Through Point Curve , Intersection Curve , and Helical Curve features.

  2. In the Projection Curve dialog box, click one of the following:
    OptionDescription
    Along Direction

    Projects selected items on a target towards the specific direction. For planar items, the direction is automatically computed.

    You can specify the direction by selecting one of the following:

    • A line
    • A plane whose normal is the direction of projection
    • The X, Y, or Z planes
    Normal to Target .

    Projects the selected items normal to the target.

  3. Click in the Items to Project field and from the work area, select sketch entities or edges.
    A context toolbar with Select Chain option appears.

    Note: Click Select Chain to project a chain of the selected item on a target.

  4. Click in the Target field and from the work area, select faces or planes.

    Note: To project along the specific direction, Select planar faces, planes, egdes, or axis systems.

  5. Optional: Under Advanced,
    1. From the Smoothing list, select one of the following:

      None Disables smoothing.
      Tangency Enhances the current continuity to be tangent continuous.

      Specify a value in the Deviation field.
      Curvature Enhances the current continuity to be curvature continuous.

      Specify a value in the Deviation field.

    2. Select 3D smoothing to smooth the projected elements without specifying any support surface.
    3. From the Extrapolation mode list, select one of the following:

      None Disables the Extrapolation mode.
      Tangency Extrapolates the entity's extremities in tangency to the surface boundary.

      Curvature Extrapolates the entity's extremities in curvature to the surface boundary.

  6. Click .
