HOUSING Part - First Rib and Linear Pattern Feature

The Rib , feature adds material between contours of existing geometry. Use Ribs to add

structural integrity to a part.

A Rib requires:

• A sketch

• Thickness

• Extrusion direction

The first Rib profile is sketched on the Top Plane. A 1 ° draft angle is required for

manufacturing. Determine the Rib thickness by the manufacturing process and the

material.

, 1 /

;Q;. Rule of thumb states that the Rib thickness is Yz the part wall thickness. The Rib

thickness dimension is .100 inches, [2.54mm] for illustration purposes.

The HOUSING requires multiple Ribs to support the BATTERY. A Linear Pattern

feature creates multiple instances of a feature along a straight line. Create the Linear

Pattern feature in two directions along the same vertical edge of the HOUSING.

, 1 /

;Q;. The Instance to Vary option in the Linear Pattern PropertyManager allows you to

vary the dimensions and locations of instances in a feature pattern after it is created. You

can vary the dimensions of a series of instances, so that each instance is larger or smaller

than the previous one. You can also change the dimensions of a single instance in a

pattern and change the position of that instance relative to the seed feature of the pattern.

For linear patterns, you can change the spacing between the columns and rows in the

pattern.
