The manipulator frame is composed of two lines, with 8 chambers on each line. In this page, we show how to sketch that using Linear Sketch Pattern and Move Entities operators.
Here is the sketch of a single chamber with inner grooves finished in last step.
We use Linear Sketch Pattern operator and pattern it as below, with instances as 8 and spacing as 5.5 mm.
Click Accept (green check mark on the left), and finish the pattern. The result is shown below.
Then, enable Move Entities operator, and select start point and end point at the red points shown below.
Click Accept, and get the sketch below.
