In this page, we first create instances from the imported parts for 'frame' and 'air bag', move the air bag towards proper position, and then replicate airbags in each chamber of the manipulator frame.

#### Create instance

Instances are created from imported **Parts** named 'frame' and 'air bag' in page 'Part', and we select instance type as **Dependent (mesh on part)**.

#### Position air bag

Now the airbag has to be positioned properly. Firstly, the air bag is rotated 90 degrees around x-axis, forming a result posture shown as below.

Next, the air bag should be translated into a chamber of the manipulator frame, which is implemented based on a translation vector from the magenta point towards the orange point illustrated below.

Then, we rotate the whole structure 90 degrees around y-axis, and the result is shown like this.

#### Linear pattern

Last, airbags are generated using **Linear pattern**, and set the **Number** as 32, **Offset** as 5.5 in **Direction 1**.
