$4.$ General Draw as a single composite solid the desk organizer shown in the orthographic views. Then, use primitive and subobject editing procedures to create the following edits. The final object should look like the shaded view.

A$.$ Change the $3^{\text{'}\text{'}}$ height to ${3\mathrm{.}25}^{\text{'}\text{'}}.$

B$.$ Change the $2^{\text{'}\text{'}}$ height to ${1\mathrm{.}85}^{\text{'}\text{'}}.$

C$.$ Increase the thickness of the long compartment divider to ${\mathrm{.}5}^{\text{'}\text{'}}.$ The increase in thickness should be evenly applied along the centerline of the divider. Locate three evenly spaced, $\frac{O}{5}\frac{?}{{16}^{\text{'}\text{'}}}{1\mathrm{.}5}^{\text{'}\text{'}}$ holes in this divider.

D$.$ Angle the top face of the rear compartments by $30.$ The height of the rear of the organizer should be approximately ${4\mathrm{.}5}^{\text{'}\text{'}}$ and all corners on the bottom of the organizer should remain square.

E$.$ Save the drawing as P$11-4.$
