Creating Projection Curves

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

Before you begin: Create a 3D shape containing a surface and at least one wire element.
  1. From the Modeling section of the action bar, click Projection .
  2. In Projection Item , select one or more items from the work area to project.

    You can select any sketch entities, edges, or vertices.

  3. In Projection Target , select the target face or plane from the work area.
  4. Select one of the following projection types:
    OptionDescription
    Normal Projects the element normal to the projection target.
    Direction Projects the element along a direction. From the Projection Selection field, you can define the direction by selecting one of the following:
    • A line
    • A plane (projection direction will be normal to the plane)
  5. Optional: Select one of the following extrapolation modes:
    OptionDescription
    No Extrapolation The projected entity is not extrapolated.
    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. Optional: Select one of the following smoothing modes:
    OptionDescription
    None No smoothing.
    Tangency Enhances the current continuity to tangent continuity.
    Curvature Enhances the current continuity to curvature continuity.
    Deviation Specifies the maximum deviation for tangency or curvature smoothing.
    Note: Only available when Tangency or Curvature smoothing is selected.
  7. Optional: Select 3D Smoothing to smooth the projected element without specifying any support surface.
