Solid Modeling In The Real World
Mechanical and Aerospace engineers need solid models of jet engine
components and assemblies to do analysis on for component strength
under high stresses and temperatures. This method of analyzing
components for strength is called finite element analysis and is growing
more popular in industry as a tool for predicting part viability.
Today’s Objectives

SolidWorks Layout
 Starting SolidWorks
• Three Main Options
• Part File Layout
• Tool Ribbon
• 3D Part Creation
• Model Tree
• View Options
• Mouse Options
Starting SolidWorks
The new file icon will
bring up the following
dialog box
Also notice the Tutorials icon for
extra help learning SolidWorks
SolidWorks Part File Layout
Tool bar ribbon
View Options
Model Tree
SolidWorks Part File Layout
Status Bar
Information Line
Units Control
SolidWorks Tool Ribbon
Two most commonly used tabs:
Features and Sketch
SolidWorks 3D Part Creation
The tool ribbon
shows the tools
available for
creating 3D parts
from 2D sketches
SolidWorks Model Tree
The left hand side of
your SolidWorks menu
is known as the Model
In a new part file it only
shows the original 3
reference planes and
the origin
SolidWorks Model Tree
The Model Tree keeps
track of the model
creation by showing the
sketches or features
used in order from top
to bottom
Notice that the sketches are no
longer shown once used for a
feature but can be accessed by
clicking the plus sign next to
that feature
SolidWorks Viewing Options
Viewing Option Layout
In the top
middle of the
workspace there
is a view menu
“Normal to” view
option orients to
a selected plane
or surface
SolidWorks Display Options
The other icons
control zoom,
section views,
display type and
other advanced
Shadows and RealView
Graphics (reflections)
should be turned off
before printing
SolidWorks View Selector Cube
The View Cube
allows the user to
see and select
model views.
SolidWorks Mouse Buttons
Left Click and
Drag is a
Selection Tool
The Mouse Wheel
• Rotate wheel to zoom in/out on cursor
• Push down and hold on the wheel to rotate
objects in 3 dimensions

SolidWorks Layout Practice
Open this file in SolidWorks
and familiarize yourself with
the view options as well as
zooming in and out. Also
become familiar with
navigating with the middle
mouse button
2D Sketching
ENGR 1182
SolidWorks 01
2D Sketches
Closed loop shape that is drawn on
a flat 2D plane (referred to as a
datum) and is used to create 3D
2D Profiles consist of:
• Points
• Lines
• Circles
• Arcs
• Etc.
Orientation of Sketch
• Pick Starting Plane
• Top planes
• Consistent shapes
from top to bottom
• Front and Right
• Consistent shapes
from left to right
Design Sketching
• Closed Loop
• Created from Lines,
Circles, and Arcs
• Nested Loops
• Errors
SolidWorks: Main Interface
The tool bar ribbon options
will update automatically to
match the current status of
the model
SolidWorks: Sketching
Basic Tools
Tool Ribbon
Lines and Circles are the
most important tools
Also important are Arcs and
Most objects can be
created using these
The dropdown arrows next to
each icon contain more
options for each tool type
SolidWorks: Sketching
Advanced Tools
Trim can be used to
remove excess lines
Offset can be used to
duplicate a profile either
inside or outside the
These tool options are not
required but can help
reduce the time it takes to
create a sketch
Tool Ribbon
SolidWorks: Sketching
The Line tool will continue to
start a new line from the
previous end point until ESC
is pressed
Circles and Arcs can be
added to the profile
SolidWorks: Trimming
Another option for
creating the arc is to
start with a full circle
and then trim away the
excess material
“Trim to closest” is the
option that was used to
remove part of the circle
SolidWorks: Trouble
Extra lines can be deleted
by left-clicking and using
the delete key
Processes can be reversed by the
Undo Function (Ctrl Z) or a list of
operations can be viewed using
the undo menu at the top of the
user interface
SolidWorks:2D Fillets
Adding a fillet shortens the
two lines and the sharp
corner is replaced by a
rounded corner
Fillets can be added to two
lines that originally intersect
SolidWorks: Exiting a Sketch
Two options are available for
Exiting a Sketch and saving
any changes made
2D Sketching Wrap-Up
 Profiles
• closed loop shape that is drawn
on a flat 2D plane
 Main Tools
• Circles
• Lines
 Acceptable Profiles
• Closed Loop
 Trim
• removes excess of lines
Out-of-Class Assignment
Re-create the shape from the
lecture slides on the FRONT
plane. Focus on shape and
proportionality not dimensions
(the fillet was chosen because
of the relative size of the
members, not for an exact
Important Takeaways
 Layout of SolidWorks
• Tool Ribbon
• Model Tree
• View Options
 2D Sketching
• Basic and Advanced Tools
 The homework from todays class is to
complete the in-class exercises. In future
class sessions there will be an in-class activity
and an out-of-class assignment. Only the outof-class assignment will be collected.
What’s Next?
 Due Next Class: SW01 Out of Class HW
 Before next class, you will read about
the extrusion and revolution tools of
solid modeling
 The extrusion and revolution features
are used to create 3D shapes using a
2D sketch.
 Take SolidWorks 2 Quiz on readings
