Defining Profile Rib Features
In order to define the Rib feature thickness you must:
Set a numeric value for the rib thickness.
Determine the rib material side with respect to the sketching plane.
You can set a numeric value for the rib thickness either by dragging the handles to the desired length or by typing or selecting a real number value in the dimension box. The dimension box contains the most recently used dimension values.
You can determine the accurate material side for the rib using the preview geometry. Setting the Rib feature material side is a two step process. First, you must point the direction arrow towards the side of the sketch line to fill. In most cases you will accept the default direction.
Accept Default Direction
Optional Direction Arrow
You must accept this direction so the Rib feature is filling an enclosed area.
You can choose either direction because both options fill an enclosed area.
Second, you must determine how to thicken the Rib features about the sketching plane: symmetrical or towards one side of the sketching plane. The default material side is both sides, however, as you define and redefine your Rib features you can change material sides using either the shortcut menus, the dimension box, or the Profile Rib tab.
Side One (one side)
Side Two (one side)
Both Sides (symmetrical)
The following table displays the processes for changing material sides. Clicking on the Profile Rib tab rotates through the three material side options:
Material Side Change
How to Set the New Material Side
Both sides - to - Side one or Side two
Do one of the following while defining or redefining:
Right-click the Rib feature in the graphics window and clear Symmetric on the shortcut menu.
Click on the Profile Rib tab.
Side one or Side two - to - Both sides
Do one of the following while defining or redefining:
Right-click the Rib feature in the graphics window and click Symmetric on the shortcut menu.
Click on the Profile Rib tab.
Side one - to - Side two (and vice versa)
Do one of the following while defining or redefining:
Right-click the Rib feature in the graphics window and click Flip on the shortcut menu.
Drag the preview geometry to the opposite side.
Type a negative value in the dimension box.
Click on the Profile Rib tab.
