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.

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 Part File Layout
Status Bar

Information Line
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 Tree
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
Front
Top
Bottom
RightLeft Back
In the top middle of the
workspace there is a
view menu
“Normal to” view option orients to a
selected plane or surface
Viewing Option Layout
SolidWorks Display Options
The other icons control zoom, section views,
display type and other advanced
options Shadows and RealView Graphics
(reflections) should be turned off before
printing assignments
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

Homework Assignment SW01-OUT:
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 1182SolidWorks 01
2D SketchesProfiles:
Closed loop shape that is drawn on a flat 2D plane (referred to as a datum) and is used to create 3D objects.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 planes
• Consistent shapes from left to right
Design Sketching
Acceptable Profiles• Closed Loop• Created from
Lines, Circles, and Arcs
• Nested Loops• Errors
SolidWorks: Main InterfaceThe tool bar ribbon options will update
automatically to match the current status of the
model
SolidWorks: Sketching Basic Tools
Lines and Circles are the most important tools
Also important are Arcs and Fillets
Most objects can be created using these options
Tool Ribbon
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 original
These tool options are not required but can help reduce the time it takes to create a sketch
Tool Ribbon
27
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 “Trim to closest” is the option that was used to remove part
of the circle
Another option for creating the arc is to
start with a full circle and then trim
away the excess material
SolidWorks: Trouble Shooting
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
Fillets can be added to two lines that originally
intersect
Adding a fillet shortens the two lines and the
sharp corner is replaced by a rounded corner
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 AssignmentRe-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 dimension).
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 out-of-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.
