Ribs that are parallel to the sketch plane use an open profile to create a single support shape. The specified thickness is normal to the sketch plane and the material is extruded planar to the sketch:
Ribs that are normal to the sketch plane, also called webs, use an open or closed profile to create a support shape. The specified thickness is planar to the sketch plane and the material is extruded normal to the sketch:
Before defining the rib, set the sketch plane and create the profile geometry. If desired, use a work plane as the sketch plane. Click 2D Sketch and then click the work plane or a planar face to set the sketch plane. Use commands on the Sketch tab to create the profile to represent the rib shape.
On the ribbon, click 3D Model tab Create panel
Rib
.
If the profile is not selected, select it.
Set the direction of the extrusion:
Click a Direction to specify which way the rib is extruded.
If there are multiple bodies in the part file, select the Solids selector to choose the participating body.
The Extend Profile check box displays if the ends of the profile do not intersect the part. The ends of the profile extend automatically. Clear the check box to create a rib or web the exact length of your profile.
In the Thickness box, enter a value for the width of the rib or web. Click a Flip icon
to apply the thickness to one side of the profile or extend it equally on both sides of the profile.
Set the depth of the rib:
(Optional) In the Taper box, enter a taper or draft value for the rib or web. To apply a taper value, the direction must be perpendicular to the sketch plane.
(Optional) For ribs that are normal to the sketch plane, specify additional parameters in the Draft and Boss tabs of the Rib dialog box:
Draft tab
Boss tab
Click OK.
