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

SolidWorks Part File Layout

Tool bar ribbon

Model Tree

View Options

SolidWorks Part File Layout

Status Bar

Units Control 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 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

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 1182

SolidWorks 01

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.

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 Interface The 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

SolidWorks: Sketching 27

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 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).

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.
