Rib command

Constructs a rib by extruding a profile. The Direction and Side steps allow you to control the shape of the rib.

Constructing a synchronous rib feature

When you choose the synchronous Rib command, the command bar guides you through the following steps. The Rib command requires an existing sketch.

Step 1.	Select Step--Select the sketch elements that define the rib feature.
Step 2.	Rib Thickness Step--On the dynamic edit box, type in the rib thickness value and press the Tab key.
Step 3.	Extent Step--Option to extend the ends of the sketch elements until they intersect the part.
Step 4.	Finite Depth Step Option on-Sets the rib extent so that the sketch elements are projected a specified distance to either side of the profile plane. (The rib does not project all the way to the existing faces on the part.) Type the distance in the value edit box. Option off-Extends the faces on the rib that are perpendicular to the sketch plane to the existing faces on the part.
Step 5.	Alignment Step--Define the side of the sketch to create the rib on.
Step 6.	Side Step--Use the steering wheel to define direction for the rib.
Step 7.	Finish Step--Click the Accept button to create the feature.

Constructing an ordered rib feature

When you select the Rib command, the command bar guides you through the following steps:

Step 1.	Plane or Sketch Step--Define the profile plane for the rib or specify that you want to use an existing sketch.
Step 2.	Draw Profile Step--This step automatically activates when you define the reference plane for the rib. When editing a rib, you can select this step to edit the rib profile.
Step 3.	Direction Step--Define the direction you want to project the profile to form the body of the rib.
Step 4.	Side Step--Define the side to which you want to offset the profile to form the thickness of the rib. Note: By default, all ribs offset symmetrically. If you do not want the rib offset symmetrically, click the Side Step button, and define the side of the profile you want to offset.
Step 5.	Finish Step--Process the input and create the feature.
