2. 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.

Mouse Options

6. Starting SolidWorks
The new file icon will bring up the following dialog box
SolidWorks is started from the Start menu.
The 3 new files icons represent part files, assemblies, and drawings. Currently we’re going to start with the basic building block of any project and that is part files.
Also notice the Tutorials icon for extra help learning SolidWorks

9. SolidWorks Tool Ribbon
Two most commonly used tabs: Features and Sketch
Features tab is 3D operations, Sketch is 2D.
Operations that are not currently available are gray.

10. SolidWorks 3D Part Creation
The tool ribbon shows the tools available for creating 3D parts from 2D sketches

11. The left hand side of your SolidWorks menu is known as the Model Tree
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
The model tree shows the creation of the part from top to bottom. The top is the beginning operations and the bottom is the last operations.

12. 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
The model tree shows the creation of the part from top to bottom. The top is the beginning operations and the bottom is the last operations.

13. SolidWorks Viewing Options
Viewing Option Layout
In the top middle of the workspace there is a view menu
Top
Left
Front
Right
Back
“Normal to” view option orients to a selected plane or surface
The layout of available views is not labeled but it should be easy to recognize the views from their layout.
Bottom

14. 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

15. SolidWorks View Selector Cube
The View Cube allows the user to see and select model views.

16. 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

18. 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

19. 2D Sketching
ENGR 1182
SolidWorks 01

20. 2D Sketches
Profiles:
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.

21. Orientation of Sketch Pick Starting Plane Top planes
Consistent shapes from top to bottom
Front and Right planes
Consistent shapes from left to right
The orientation of the 3D part is first determined by the location of the 2D sketch
The designer can select the appropriate plane to start the sketch depending upon the desired shape
Top planes can be used to create base features that are consistent shapes from top to bottom
Front and Right planes are used to create base features that are consistent shapes from left to right

22. Design Sketching
User inputs (mouse clicking) are approximate values that are interpreted by the parametric design software to exact locations.
These “guesses” by the computer are usually desired in order to create a closed loop profile and have the endpoints of lines match up

23. Acceptable Profiles Closed Loop Created from Lines, Circles, and Arcs
Nested Loops
Errors
A closed loop profile is a profile that has a concise number of 1D pieces that define a desired 2D shape
Solid lines are 1D entities that must be connected to other lines in order to create a closed loop
Nested loops are profiles where the space between the outer and the inner lines defines the space
Errors occur when there 1D entities that do not form a closed loop and examples are shown to the right

24. SolidWorks: Main Interface
The tool bar ribbon options will update automatically to match the current status of the model

25. SolidWorks: Sketching Basic Tools
Tool Ribbon
Lines and Circles are the most important tools
Also important are Arcs and Fillets
Most objects can be created using these options
The dropdown arrows next to each icon contain more options for each tool type

26. SolidWorks: Sketching Advanced Tools
Tool Ribbon
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

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

28. 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

29. 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

30. Fillets can be added to two lines that originally intersect
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

31. SolidWorks: Exiting a Sketch
Two options are available for Exiting a Sketch and saving any changes made

32. 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
The dimensions are not as important as the shape

33. 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 dimension).
Start with the simple shape but then if the student wants they can move on to the harder image

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.

35. 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.
