In this lesson, you will create the basic geometry of the model, then use 3ds Max modifiers to give the object a distinctive shape.
Set up the lesson:
A daylight system has already been set up, so you can start building your model right away.
Create the tower object:
Do not worry about dragging the box to an exact width, depth, or height. You will set these parameters in the next step.

Parameters rollout, set the parameters of the box as follows:

The segments are necessary to define the tower floor and window grid.


This name change is appropriate, since you will later be applying a glazing material to this object.
Object-Space Modifiers section, choose Taper.

The negative Amount value tapers the building inwards at the top. The negative Curve value pulls the sides of the building in, as shown in the next illustration.

Next, you want to give the tower a twist.
Object-Space Modifiers section, choose Twist.
Twist group, set Angle to
90.0 and Bias to
45.0.

The 90-degree Twist value creates a quarter turn of the building. The Bias value of 45 causes the twist to start part-way up the side of the building, rather than immediately at its base.

Object-Space Modifiers section, choose FFD(box). Free-Form Deformation ("FFD") modifiers surround the selected geometry with an adjustable lattice box.
Dimensions group, click Set Number Of Points.

This lets you select and manipulate the lattice control points you defined in the previous step.

(Select And Move), then drag right slightly, as shown in the next illustration.

Now you are ready to create the mullions.
