Extruding Open Profiles
You extrude open profiles to create rib features and thin features.
For more information about sketching open profiles, see “Creating Open Pro-
file Sketches” on page 46.
Creating Rib Features
To create a rib feature on a part model, you sketch an open profile to shape
the rib, define the thickness of the rib, and extrude it to part surfaces.
Observe these rules when you sketch open profiles for ribs:
■ Sketch the side view of the rib.
■ The sketch can have any number of segments.
■ The ends of the sketch need not touch surfaces the rib will attach to, but
when extended must meet valid active part surfaces, without holes in the
extrusion path.
You solve the sketch to create an open profile, and apply parametric con-
straints and dimensions as with any other profile sketch.
Like other features, the rib feature can be edited and it has dependencies. If
you delete something in your model that a rib feature depends upon, such as
a face that a profile plane is based on, you delete the rib feature as well.
