Using a Visual Style
The object you have created is now a 3D solid. If the drawing was based on the
acad3D.dwt
template, the model is displayed in the
Realistic
visual style. If the drawing
was based on the
acad.dwt
template, the model is displayed in the
2D Wireframe
visual
style.
As mentioned previously, there are 10 different visual styles from which to choose.
Select an option from the
Visual Style Controls
fl yout in the viewport controls or the
View
panel on the
Home
tab of the ribbon. The
Conceptual
visual style provides a quick
display of the model using shaded tones of the object color, as shown in Figure 1-22.
The techniques used in this example are just a brief introduction to the creation
of 3D models. Detailed descriptions of modeling, display, and editing techniques are
included in the following chapters.

Working in 3D, like working with 2D drawings, requires careful planning to effi ciently
produce the desired results. The following guidelines can be used when working in 3D.
Planning
• Determine the type of fi nal drawing you need and the manner in which it will
be displayed. Then, choose the method of 3D construction that best suits your
needs—wireframe, surface, mesh, or solid.
• If appropriate for the project, use 2D constraints to create a 2D layout or sketch.
• For an object requiring only one pictorial view, it actually may be quicker to
draw an object in 3D rather than in AutoCAD’s isometric mode. AutoCAD’s 3D
solid modeling tools enable you to quickly create an accurate model, and then
display it in the required isometric format using preset views. The
VIEWBASE
command can then be used to create a 2D drawing of the model.
• It is best to use AutoCAD’s 3D commands to construct objects and layouts that
need to be viewed from different angles for design purposes.
• Construct only the features needed for the function of the drawing. This saves
space and time, and makes visualization much easier.
• Use 2D or 3D object snap modes in a pictorial view in conjunction with UCS
icon manipulation to save having to create new UCSs.
• Keep in mind that when the grid is displayed, the pattern appears at the current
elevation and parallel to the XY plane of the current UCS.
