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

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.
