Lesson 01
Creating a Basic 3D Surface Model
Elevation & Thickness
To work in three dimensions in AutoCAD, we need to use a third axis on the rectangular
(Cartesian coordinate system. This axis (defined as Z), determines the depth of an object. In
this context, the X-axis will identify the WIDTH, the Y-axis LENGTH and the Z-axis
determines the DEPTH of an object.
1. Start a new file from scratch. Accept all the default settings.
2. Turn the Grid and Snap ON (F7 & F9), and use the default spacing.
3. Create a new layer named object, assign the color green to it, and make it the current
layer.

1. AutoCAD Workbook 3D
4. Enter the ELEV Command and set the new default elevation at 1” and the new
default thickness at 3”.
5. Begin you drawing with the LINE Command, and construct the figure 1.
Do not be concern about the exact sizes. Keep your drawing proportional to one
shown in Figure 1.

3D solids:
• Uniform-width wide polylines with thickness
• Closed, zero-width polylines with thickness

Sweep Command
With the SWEEP command, you can create a new solid or surface by sweeping an open

solid or surface in the shape of the specified profile along the specified path. You can
sweep more than one object, but they all must lie on the same plane

Loft Command
With the LOFT command, you can create a new solid or surface by specifying a series of
cross sections. The cross sections define the profile (shape) of the resulting solid or
surface. Cross sections (generally, curves or lines) can be open (for example, an arc) or
closed (for example, a circle). LOFT draws a solid or surface in the space between the
cross sections. You must specify at least two cross sections when you use the LOFT
command.

3dalign Command
You can specify either one, two or three points for the source object. Then, you can
specify one, two, or three points for the destination. The selected object is moved and
rotated so that the base points, and the X and Y axes of the source and destination align in
3D space. 3DALIGN works with dynamic UCS (DUCS), so you can dynamically drag
the selected objects and align them with the face of a solid object.

SHELL
Shelling creates a hollow, thin wall with a specified thickness. You can specify a constant
wall thickness for all the faces. You can also exclude faces from the shell by selecting
them. A 3D solid can have only one shell. New faces are created by offsetting existing
ones outside their original positions.
The descriptions of the Undo, Remove, Add, and All options match the descriptions of the
corresponding options under Extrude. After you select faces or enter an option, the following
prompt is displayed:
Remove faces or [Undo/Add/ALL]: Select a face (1), enter an option, or press ENTER. Enter the
shell offset distance: Specify a distance
Specifying a positive value creates a shell to the inside perimeter of the solid; specifying
a negative value creates a shell to the outside perimeter of the solid.

Creating Section Planes
Section objects have three states: Section Plane, Section Boundary, and Section Volume.
Depending on the state you choose, you can view the cutting plane as a 2D plane, a 2D
box, or a 3D box. Grips allow you to make adjustments to the length, width, and height of
the cutting area.
• Section Plane. The section line and transparent section plane indicator display.
The cutting plane extends infinitely in all directions.
• Section Boundary. A 2D box shows the XY extents of the cutting plane. The
cutting plane along the Z axis extends infinitely.
• Section Volume. A 3D box shows the extents of the cutting plane in all directions.
