SOLIDWORKS: Lesson 1 -

Basics and Modeling

UCF Engineering


2/57

SolidWorks

SolidWorks is a 3D solid modeling package

which allows users to develop full solidmodels in a simulated environment for bothdesi n and anal sis.

In SolidWorks, you sketch ideas and

experiment with different designs to create3D models.


3/57

SolidWorks

SolidWorks is used by students, designers,

engineers, and other professionals toproduce simple and complex parts,assemblies and drawin s.

Designing in a modeling package such as

SolidWorks is beneficial because it savestime, effort, and money that would otherwisebe spent prototyping the design.


4/57

SolidWorks Components - PARTSBefore we begin looking at the software, it is importantto understand the different components that makeup a SolidWorks model.

The first, and most basic element of a SolidWorks model isa Part.

Parts consist of primitive geometry and features such as

extrudes, revolutions, lofts, sweeps, etc.

Parts will be the building blocks for all of the models that

you will create


5/57

SolidWorks Components - Assemblies

The second component is the assembly.

Assemblies are collections of parts which areassembled in a particular fashion usingmates constraints .

Any complex model will usually consist of

one, or many assemblies.


6/57

SolidWorks Components - DRAWINGS

The third, and final component in

SolidWorks is the Drawing.

A drawin is the t ical wa to re resent a

3D model such that any engineer (ormanufacturer) can recreate your part.

Drawings are important because they providea standard way of sharing your design.


7/57

SolidWorks Lets Begin By default, no file is opened

automatically when youstart the program.

To create a new file, clickon File > New or click the

toolbar.

This will open the New

SolidWorks Documentwizard.


8/57

SolidWorks Tour


9/57

SolidWorks Tour

Lets begin by creating

a new part. To do this,click on Part, then OK

Once you do this, you

will be brought into themodeling view whichshould open severaltoolbars and panes


10/57

SolidWorks Tour There are severalimportant parts of thescreen that needs to be

identified before wecontinue.

First the left side of the

screen consists ofseveral tabbed panesthat provide veryimportant information

regarding your model.


11/57

SolidWorks Tour The first tab, called the

Feature Manager, lists all

features that have beencreated within your model.

This tab is extremely

important as it will be fromhere that you select andchange features once theyhave been created.


12/57

SolidWorks Tour The second tab, called the

Property Manager, allowsyou to adjust the propertiesof various entities eitherduring construction, or

.

Note that generally you willnot need to manuallychange the tab on themanager window


13/57

SolidWorks Tour The third tab is called the

Configuration Manager and isused to set up different viewconfigurations such asexploded views or 3D sectionviews.

Usually this will be used oncethe part has been created andyou wish to set up specific

configurations forvisualization.


14/57

SolidWorks Tour

There may also be other tabs

visible in the managerwindow.

Generally any time you load

an a ona o or smodule (such as PhotoWorks,COSMOS Motion, COSMOSWorks, etc.) it will create a

new tab in this window.


15/57

SolidWorks Tour

The next important feature of the interface is

the dynamic Toolbar

The dynamic Toolbar provides access to the

most relevant, and frequently use commandsin SolidWorks


16/57

SolidWorks Tour

The last part of the interfacewhich should be noted is the Task

Pane on the right side of thescreen.

Using the Task Pane you can

as importing standard geometry,file explorer, view palette, as wellas any plug-in specific

information.


17/57

SolidWorks Tour The last thing that needs to be shown is how to open the

SolidWorks tutorials.

They can be accessed by going to Help > SolidWorks Tutorials.

The tutorials are very helpful and cover from the most basicfeatures to more advanced analysis and assemblies


18/57

SolidWorks Exercise

Now that we have explored the interface of

SolidWorks, lets create a simple part step-by-step.

For now, we are only going to concernourselves with two types of features,Extruded Boss/Base and Extruded Cut.


19/57

SolidWorks ExerciseWe wish to model the following part:


20/57

SolidWorks Exercise What is Extrude?

Extrude When you take a 2D

area and push the designout into another dimension.

A 2D area, for example, canbe made into a 3D volume

y ex ru ng ou a spec cdistance, d.

You can extrude to make a

SOLID or you can extrudeto make a CUT


21/57

SolidWorks Exercise

There are MANY ways to EXTRUDE a surface

We could make thisrectangle and EXTRUDE itDOWN or UP

This rectangle

could be madefrom the side

or bottom andextruded.

You could EXTRUDE thisrectangle and pull it tothe left or right

A rectangle could be

made here on top of thefirst surface, thenextruded down to make

the cut.


22/57

SolidWorks Exercise

Lets begin by selecting

EXTRUDED Boss BaseYou should notice that your tab will change toproperty manager asking you to select a plane from

the view.


23/57

SolidWorks ExerciseGo ahead and select the

horizontal plane shown.

You should notice several things happen.1. You switch to feature manager2. You have sketch buttons on the dynamic toolbar3. You view below is shown as TOP VIEW! You are

looking down on top of the part.


24/57

SolidWorks Exercise

Click on Rectangle. Youshould see your cursor

change to a rectangle with a

pencil which means you aresketching.

Make a rectangle by dragging themouse from one corner of thescreen to the other. The size

does not matter at this point.


25/57

SolidWorks Exercise

If you hit escape, it will get youout of the rectangle TOOL

and back to a normalcursor.

rectangle however.

At the bottom right of your screen you will see the figure above.Obviously, we are in the middle of our sketch but it also says, UnderDefined. This means that there are parts of the sketch that are not

defined according to location.


26/57

SolidWorks Exercise

Click the bottom right point on

the rectangle.

this point around as itslocation is NOT defined.

This point has degrees of

freedom and is NOTconstrained.


27/57

SolidWorks Exercise Lets save our work!Click on the small box next to the far rightvertical line. Notice this box turns pink whenclicked and that it has a vertical line in it.This means that this line is vertical and when

you click on it you can move it left or right.The vertical lines can thus be moved up ordown.

,

top right point. Notice the line is not definedas a vertical line anymore and the degreesof freedom are extended.

The horizontal line still moves up or down,

but notice the vertical line can be moved inany direction as you deleted the relationship.


28/57

SolidWorks Exercise

You can add relations by

clicking on a line, turnsgreen.

Line ro erties will a ear and

you can click on theVERTICAL button on the

ADD RELATIONS windowsto constrain the line to just

the vertical direction.


29/57

SolidWorks Exercise

To ZOOM you can use the mouse wheel or

hit the Shift button and move mouse

mouse

To fit a picture to a window simply press thef letter key on the keyboard to FIT.


30/57

SolidWorks ExerciseNow we want to add specific

dimensions to our drawing. ChooseSMART DIMENSION on thedynamic toolbar.

Click the bottom horizontal line ofour rectangle and drag thedimension down.

You can change the length of the line by using the slider bar or you can

simply enter in 4 m in the box shown. Enter the value 4 then click thegreen check. Since the box is way too big, press f on the keyboard to

fit. Then drag down the dimension so that you can see it after hittingescape.


31/57

SolidWorks ExerciseNow using Smart Dimension

again lets dimension the leftvertical line. You may need

to zoom or pan to view theline to click on.

Modify the Length to be 2 unitsas shown in the original

drawing.


32/57

SolidWorks Exercise

Hit Escape, then f to fit.

You should see a 2 x 4rectangle.

If you click the top right corner, you see you can

move the entire rectangle. The entire drawing has

yet to be defined in terms of its location relative tothe plane,


33/57

SolidWorks ExerciseTo make the drawing fixed in

the plane we can make onepoint coincident with theorigin. Choose the top leftpoint.

Press CTRL, then select theorigin.

You will notice that underselected entries you have TWOitems chosen. Under ADD

RELATIONS you seeCoincident. Choose this buttonand you will see the origin move

to that point.


34/57

SolidWorks Exercise

Choose ok (green check). You should see all of the lines turn black.

Click in the top right corner toEXIT the SKETCH.


35/57

SolidWorks Exercise

When you exit the sketch

you should see yourdimensions and sketchin the plan you choose.

in the middle of yoursketch. Click on thearrow and move

upward.


36/57

SolidWorks Exercise

As you drag it upward you

should see the volumelike structure shown.

You can also EXTRUDEthe shape down.


37/57

SolidWorks Exercise

Drag the surface upward andrelease to select a volume.Under the properties

manager we see severalDIRECTIONS we can takethis surface. Just chooseBLIND.

The D1 you seemeans depth andwe see from ouroriginal picture we

want a depth of 1.So enter 1, thenclick OK.


38/57

SolidWorks Exercise

We now have our first

SOLID piece.

You should also notice we

have a ton of newfeatures available aswell.


39/57

SolidWorks ExerciseSolidworks is a PARAMETRIC design tool, meaning the edges

are always driven by dimensions. So it is very important thatyour drawing be fully defined. Notice under features managerEXTRUDE now appears on the list. Double click on this or

expand. You now see the design in terms of its dimensions.


40/57

SolidWorks Exercise

Click on the width dimensionand change the value from

2 to 3. Then click OK. Then

click exit in the propertiesmanager window. Whathappened?

Notice the STOPLIGHT icon next to our sketchunder features manager. What this means is thatwe have CHANGED the design but we have yet toREGENERATE the part.


41/57

SolidWorks Exercise

Up on the dynamictoolbar you will seeanother stoplight icon,

but this time it is abutton. If you click thisbutton it will REBUILDyour par accor ng o

the changes you made.

Notice the changes in

your part.

Go ahead and make changes to the

other dimensions and rebuild to seethe effect.

THEN CHANGE THE DIMENSIONSBACK TO THE ORIGINALDIMENSIONS of 4x2x1.


42/57

SolidWorks Exercise

Lets go ahead and makethis cut!

To do this, we need to use what is called an EXTRUDED CUT.


43/57

SolidWorks Exercise

Click extruded cut andnotice what it is asking

us in the propertiesmanager tab.

We want to select planarface which is the top surfaceas shown.


44/57

SolidWorks Exercise

Click on that top surface. Whathappened? We aresketching on top of theplane but unfortunately weare not LOOKING at theplane itself. At the bottomleft you see the VIEW

.

chosen now, but if you clickthe arrow beside it otheroptions become available.

Click the NORMAL TO view.


45/57

SolidWorks Exercise

You should see now thatyou are looking directlyDOWN at the plane.

Click the rectangle button at the topand draw a rectangle of ANY SIZE

within the surface of your plane.


46/57

SolidWorks ExerciseIf you hit escape, you see that

the rectangle is certainlyUNDER DEFINED just asour last one was. So lets go

ahead an DIMENSION therectangle using our givenfigure.

When you are finished youbasically have a rectanglethan you can freely move

within the planar surface.


47/57

SolidWorks Exercise

Lets define the location of

the rectangle. Click onthe bottom left pointand press the CTRL

MULTIPLE entries.Click on the bottomhorizontal line.


48/57

SolidWorks ExerciseUnder properties manager notice the entries selected in pink.

Choose coincident under ADD RELATIONS.

Notice your point is now coincident with the

bottom surface. Click OK in the propertiesmanager window. Notice that your horizontal linesare black meaning they are fully defined. Trydragging the box

l d k


49/57

SolidWorks Exercise

Clink on smart dimension

and choose the rightvertical line of oursmaller rectangle then

of our planar surfaceedge. Then modify thedistance to 1.50 Notice we see FULLY DEFINED at the

bottom of our screen and that all of ourlines are black meaning NO freedom ofmovement.

S lidW k E i


50/57

SolidWorks Exercise

Click OK in propertiesmanager then EXITsketch in the top right.

The view will not beseen from the point ofview we can extrude so

choose a different viewfrom below. ChooseISOMETRIC.

S lidW k E i


51/57

SolidWorks ExerciseFrom the property manager

window under Cut-Extrude wecan choose a direction.Choose THROUGH ALL as wewant our cut to go all the way

through. Then click OK. Youshould see the complete cut.

Click and hold the mouse. You should be able to ROTATE the part in 3D space.

S lidW k E i


52/57

SolidWorks ExerciseSuppose we change the

ORIGINAL dimension of theplanar surface length from 4mto 6m.In feature manager, clickon the original extrude and

then modify the lengthdimension to 6m. Thenregenerate the part. Youshould see that the CUT is

.edge.

So the big question is .WASTHIS DESIGN INTENT?

Did we really want this 1.5 m fromthe right or did we want the cutto be CENTERED?

S lidW k E i


53/57

SolidWorks ExerciseGo ahead and change the length dimension back. In this case, the

designer had the cut centered in the original drawing. Just keepDESIGN INTENT in mind when you are trying to decide HOWto model a part.

Choose Extruded Boss/Base then choose the top planar surface.Then change your view to NORMAL TO so that you see the toplanar surface as shown.

S lidW k E i


54/57

SolidWorks Exercise

Now lets finish the top part.

Choose rectangle, sketch it

and dimension it accordingto the original drawing. Butnow lets try to center the

s e c as we now was

the designers intent to dothis. RIGHT CLICK on thetop horizontal line of your

rectangle and a window will

open. Choose SELECTMIDPOINT.

S lidW k E i


55/57

SolidWorks ExerciseYou should notice a point on your line.

Press CTRL then CLICK on the tophorizontal line of your planar surface.You should see them selected in

properties manager in pink. ChooseMIDPOINT in the ADD RELATIONSwindow.

Your rectangle is now centered at the midpoint on the top edge of the planar surface.

SolidWorks E ercise


56/57

SolidWorks ExerciseEXIT your sketch then change your

view to isometric. In propertiesmanager, use BLIND for thedirection and change the

height(D1) to be 1.50 according toour original drawing. Chooseselect to see the finished part.

SolidWorks Exercise


57/57

SolidWorks Exercise

To establish DESIGNINTENT, change theoriginal length

dimension from 4 to6m. Then rebuild the

art. You should see

the top part remaincentered and the cut1.5 m from the rightedge.
