BOX (Command)
The following prompts are displayed.

First Corner: Starts the box by setting the first corner.
Other Corner: Sets the opposite corner and height of the base of the box.
Cube: Creates a box with sides of equal length.

Length
Creates a box with length, width, and height values you specify. The length corresponds to the X axis, the width to the Y axis, and the height to the Z axis.
Entering a positive value draws the height along the positive Z axis of the current UCS. Entering a negative value draws the height along the negative Z axis.
The base of the box is always drawn parallel to the XY plane of the current UCS (work plane). The height of the box is specified in the Z-axis direction. You can enter both positive and negative values for the height.
CYLINDER (Command)
Creates a 3D solid cylinder.
In the illustration, the cylinder was created using a center point (1), a point on the radius (2), and a point for the height (3). The base of the cylinder is always on a plane parallel with the workplane.
The following prompts are displayed.
3P (Three Points): Defines the base circumference and base plane of the cylinder by specifying three points.
2Point: Specifies that the height of the cylinder is the distance between the two specified points.
Axis Endpoint: Specifies the endpoint location for the cylinder axis. This endpoint is the center point of the top face of the cylinder. The axis endpoint can be located anywhere in 3D space. The axis endpoint defines the length and orientation of the cylinder.
2P (Two Points):Defines the base diameter of the cylinder by specifying two points.
Additional prompts include
2Point: Axis endpoint
TTR (Tangent, Tangent, Radius).
