Solid Modeling - Swept Solids


Swept Solids
Solid primitives can also be created by:
 Extruding
 Revolving
 Sweeping
an existing two-dimensional closed
object
The closed two-dimensional objects are
called closed profiles
All primitives can be created with a
sweeping operation


Extruded Solids
An extrusion is a:
Manufacturing process that involves forcing
a material through a shaped opening
Modeling process that creates a 3D shape
by translating a 2D profile along a linear
path


AutoCAD Extrusions
To create an extruded solid in AutoCAD:




Create a close polyline in xy plane of current
UCS
Extrude polyline in z direction of current UCS

NOTE: AutoCAD command - EXTRUDE


Revolved Solids
A revolution is a modeling process that
creates a 3D shape by revolving a 2D
profile along a circular path

NOTE: AutoCAD command - REVOLVE


Sweeps
A swept solid is created by moving a 2D
profile along a path

NOTE: In AutoCAD, a sweep is created via the EXTRUDE
command, using the Path option
