Tutorial
To create the shapes for the telephone receiver, you'll use some of the same techniques that you used to create the cross-sections of the base. For the receiver, you'll make three cross-sections.
Load a start file:
Continue from the previous lesson, Loft the Telephone Base, or you can open telephone_base_3d.max from the folder.
Create the receiver cross-sections:
The receiver cross-sections will be made as if looking directly down on the telephone. You will create two cross-sections; one for the mouth and ear piece at each end of the receiver, and one to represent the middle of the handle section.
If you're continuing from the previous lesson, select all the objects and shapes and right-click to open the quad menu. From the Display (upper-right) quad, click Hide Selection.
Activate the Top viewport and then drag to create a circle and set its radius.
The initial size doesn't matter because you'll adjust that next.
On the Parameters rollout, set the Radius to 10.
This produces the first cross-section.

On the Name And Color rollout, change the name to Receiver–End.
The Circle tool is still active so create another circle next to the first.
You will modify this one to represent the middle cross-section of the receiver.
On the Parameters rollout, set the new circle's Radius to 5. This is the second cross-section.

On the Name and Color rollout, change the name to Receiver–Middle.
Create one more circle and set its radius to 7 to produce the third cross-section.

On the Name And Color rollout, change the name to Receiver–Bend.
Select Receiver-Middle, then right-click and choose Convert To > Convert to Editable Spline. Do the same for Receiver-Bend.
When you convert the first spline, Autodesk VIZ displays the Modify panel so you can start editing the shape of the cross-sections.
Reshape the bend and middle cross-sections:
You could leave the cross-sections as they are, but you're going to adjust some of the vertices to give the sections a better shape, something a little more “retro” and stylish.
Drag a selection window around the top and bottom vertices.

On the main toolbar, click Select And Move to turn it on, and then move the two vertices upward, as shown in the following
illustration.

On the Selection rollout, turn on Segment mode, and then drag a selection window across both bottom segments.

Move the segments downward to match the following illustration.
In the modifier stack, click the Editable Spline entry to turn off sub-object mode.
Select the Receiver-Bend shape. Then in the modifier stack display, expand its hierarchy and click Vertex to use the Vertex sub-object level.
Drag a selection window around the top and bottom vertices.

Drag them upward slightly, so they match the following illustration.
Now you can loft the receiver.
If you wanted, you could make a selection of different end cross-sections, such as an octagonal and a square one, or different mid-handle shapes. Then while lofting, you could try the different cross-sections to see which pleases you or your clients the most.
