Rib

You can create ribs that intersect, are parallel, or at an angle with sketch entities on a plane.

  1. Sketch the contour to use as the rib feature on a plane that intersects the part, is parallel, or at an angle to an existing plane.
    The following sketch is an example using a line to create the rib.

  2. From the Features section of the action bar, click Rib .
  3. When multiple bodies are detected, select a Target Body that defines where to apply ribs.

  4. In Profiles, select a sketch from the tree or sketch entities from the work area that defines the rib.
  5. Enter Thickness value.

    Note:

    The Dimension Edit Box is displayed as you sketch. Type the value for the dimension and press Enter.

  6. Select the rib body direction.
    • Material is added to one side of the sketch that creates the rib.

      Click Toggle material side to apply material to the opposite side of the sketch profile that creates the rib.

    • Click Midplane to add material of equal thickness, to both sides of the sketch to create the rib.
  7. In the Rib Orientation section, select the rib orientation:
    OptionDescription
    Perpendicular to sketch plane. Extrudes the rib normal to the sketch plane.
    Parallel to sketch plane. Extrudes the rib along the sketch plane.
    Along direction. Extrudes the rib in the specified direction. Select an edge to specify the direction of the rib.
  8. Click Flip orientation to reverse the direction of the rib.
  9. In the Advanced Options section, select one of the following from the Profile Extension menu to extend the rib so that it meets the selected body.
    OptionDescription
    Linear Extension. The rib profile has a linear extension up to the target body.
    Natural Extension. The rib profile has a natural extension up to the target body.
    No Extension. The rib profile is not extended.
  10. Optional: Click Add draft to apply a draft to the rib.
    1. Enter a value for the draft Angle.
    2. Click to reverse the direction of the draft.
    3. Select one of the following:
      • At neutral plane - applies the thickness at the sketch that defines the rib.
      • At body intersection - applies the thickness at the intersection with the body.
  11. Click .

This is the result with the Parallel to sketch plane and No Extension options. The results depend on the selections.
