Note on the tools Union, Subtract and Intersect
The tools
Union
,
Subtract
and
Intersect
found in the
Home/Edit
panel
are known as the
Boolean
operators after the mathematician Boolean.
They can be used to form unions, subtractions or intersection between
extrusions solids of revolution, or any of the 3D Objects.
Constructing 3D surfaces using the Extrude tool
In this example of the construction of a 3D surface model the use of the
Dynamic Input
(DYN) method of construction will be shown.
1.
Place the AutoCAD drawing area in the
3D Navigation/SW Isometric
view.
2.
Click
the
Dynamic Input
button in the status bar to make dynamic
input active.
Example - Dynamic Input ( Fig. 12.36 )
1.
Using the
Line
tool from the
Home/Draw
panel construct the outline
( Fig. 12.34 ).
2.
Call the
Extrude
tool and window the line outline.
3.
Extrude to a height of
100
