A wireframe model is an edge or skeletal
representation of a real-world 3D object using lines and
curves.
You can use a
wireframe model to
View the model from any vantage point
Generate standard orthographic and auxiliary views
automatically
Generate exploded and perspective views easily
Analyze spatial relationships, including the shortest distance
between corners and edges, and checking for interferences
Reduce the number of prototypes required
Wireframe
models consist only of points, lines, and curves that describe the
edges of the object. Because each object that makes up a wireframe
model must be independently drawn and positioned, this type of
modeling can be the most time-consuming.
You can use
the XEDGES command to
create wireframe geometry from regions and 3D solids and surfaces.
XEDGES extracts all the edges on the selected objects or
subobjects.
Tips for
Working with Wireframe Models
Creating 3D
wireframe models can be more difficult and time-consuming than
creating their 2D views. Here are some tips that will help you work
more effectively:
Plan and organize your model so that you can turn off layers to
reduce the visual complexity of the model. Color can help you
differentiate between objects in various views.
Create construction geometry to define the basic envelope of
the model.
Use multiple views, especially isometric views, to make
visualizing the model and selecting objects easier.
Become adept at manipulating the UCS in 3D. The XY plane of the current UCS operates as a workplane to
orient planar objects such as circles and arcs. The UCS also
determines the plane of operation for trimming and extending,
offsetting, and rotating objects.
Use object snaps and grid snap carefully to ensure the
precision of your model.
Use coordinate filters to drop perpendiculars and easily locate
points in 3D based on the location of points on other objects.
Methods for
Creating Wireframe Models
You can
create wireframe models by positioning any 2D planar object
anywhere in 3D space, using the following methods:
Entering 3D coordinates. You enter coordinates that define the
X, Y, and Z location of
the object.
Setting the default workplane (the XY
plane of the UCS) on which you will draw the object.
Moving or copying the object to its proper 3D location after
you create it.
Wireframe
modeling is a skill that requires practice and experience. The best
approach to learning how to create wireframe models is to begin
with simple models before attempting models that are more
complex.
