Introduction

This manual has been created by student for students. While we are

competitors in this program, it is essential to share a teams gifts and

talents with other teams whose talents lie elsewhere. While other

resources for learning this application exist, I have often found myself

confused by other manuals. This Inventor Guide is designed to be a

simple but solid foundation for students who wish to learn Inventor.

It is important to note that this is merely an introductory tutorial for thisapplication and by no means should be considered a complete guide. I

strongly recommend you continue to experiment with the various tools in

this program, because my personal experiences have shown to be the

most efficient learning method.

Section 1

Inventor Layout/ Basic Controls

The following sections will give you an excellent introduction

to Inventor 11.

Section 1: Inventor layout/ basic controls

In this section, the organization of the Inventor program will be described.

This is the screen which appears

when the Inventor application is

first opened. In the top left

corner, an arrow is pointing to

the new project button. To the

right of that button, the open

project button can be found.

These two commands can also be

found in the file drop-down

menu, which is located directly

above the new project button.

Once the new project button is

pressed, the new file template

window will appear. For this

section of the tutorial, the

standard.ipt file type will be

used. Select standard.ipt and

click ok to continue, as shown

in picture 1.2.

This is the two dimensional part sketch screen. On the left, indicated by an arrow,

in the two dimensional sketch tools panel, where the basic operations, such as line-

making and polygon creation can be found like in fig 1.3.

Oftentimes in designing, an alternate vantage point of the object must be taken. In

order to do this, the rotation tool must be used. This tool is indicated by the arrow in

picture 1.4.

Fig 1.3

Fig 1.4

Once the rotationbutton is pressed, a circle

will appear which can be

used to determine the axis

of rotation by clicking in

the design window and

holding the left mouse

button and dragging in the

wanted direction, like in

FIG. 1.5.

If the space bar is

pressed while the rotation

circle visible in Fig 1.6, a

cube will appear with

green arrows pointing to

it, and clicking one of

those arrows will rotate

the part to that predefined

angle.

Sometimes when there are multiple parts or different components of one part,

such as extrusions, it is important to be able to edit one portion of the part without

having to entirely redo the part. This is the purpose of the model window in Fig. 1.7,

which is indicated by the arrow in this picture. Using various techniques which will be

described later in the tutorial, this model window can make designing an easier andmore efficient process.

At the top of the screen inFig 1.8, outlined by a rectangle,

are the pull down menu buttons,

where various functions for the

manipulation of both the part

being designed and the design

area. These include the saving

feature, which can be found in

the file submenu, and the

measuring tools, which are in

the tools submenu.

The blue area in which all design processes take place is called the graphics

window as seen in Fig. 1.9. In this area, the physical representation of the parts being

designed will appear. At the bottom of the picture where the word ready appears is the

status bar. This will display the overall condition of the current design and provides

general instructions on the use of a particular tool.

Section 2

ToolsThe following sections will give you an excellent description

of the types of tools that are used in every part.


12/49

12

2.1: Open a new Standard.ipt file as described in Section 1

2.2: In the 2D Sketch Panel, select the line tool. Click on any point in the graphics

window and drag the mouse in the direction of the line you want to create. When you are

satisfied with the length of the line, click again and the line will be created, as shown inpicture 2.2. This process can also be used to create circles, arcs, rectangles, and

polygons. You can use the General Dimension tool to change the length of the line. This

tool is also located under the 2D Sketch Panel.

Fig 2.2


13/49

13

2.3: Create three more lines so that the figure becomes a rectangle. Then in the portion

of the 2D sketch panel which reads 2D Sketch Panel with a downward arrow next to it,

click and select Part Features. This panel gives you all of the 3D commands. Click

revolve and your inventor window should look like the one shown in picture 2.3.

Fig 2.3


14/49

14

2.4: While profile is selected in the revolve options window, click the rectangle that was

just created. Then select axis and click the line around which you want the part to be

revolved. In this case choose either the top or bottom line and select OK. Rotate the part

as previously instructed and your cylinder should look like the one in Fig 2.4.

Fig 2.4


15/49

15

2.5: Once Again, open a new sketch. There is another way to change a two dimensional

figure into a three dimensional part called extrusion, Create a rectangle just like the one

made in 2.2 and 2.3. Go into the parts feature window again, but his time, select extrude.

Select the rectangle as your profile, and choose the required distance for your desired

part. For the purposes of this tutorial, select 1 in, the default option that the programprovides. Click OK and rotate and your part will look like the one in picture 2.5.

2.6: Both extruding and revolving can be accomplished with any polygon or a circle,

which can be created by selecting them in the same menu as the line feature.

2.7: At times throughout the design process, you will want to know the exact measure of

a line or arc that you create. To accomplish this, either click on the general dimension

button in the 2D Sketch Panel or simply press the D on your keyboard while the 2D

Sketch Panel is open. Then click the feature you wish to know the dimension of and

drag the mouse in the direction you want the measurement to appear. To change the

dimension of the feature, double click on the measure you want to alter and type in the

desired quantity. This can only be done in sketches!

Lead Holder

Draw two circles. Go to Tools, General dimensions, click and drag from circle. Double

click on circle and enter one .111in and the other .159in. Select in between the circles.

This should make a ring or doughnut shape. Extrude that shape 3.166 inches.

HOW TO EXTRUDE

Click the flat end of the extrusion and select 2D Sketch. Draw two circles with the same

center point of the cylinder and dimension one .111in. and the other .159in. The select

the ring and extrude .420in.

Click the flat surface of the extrusion you just created and enter 2D sketch mode. Draw

two circles and dimension them .111in. and the other .159in. Again select the ring and

Extrude 1.11 in.

If you wish to practice the revolve feature, it is possible to be created using revolve.

1. Create a two concentric circles with a diameter of 0.207 inches and a smaller

circle with a diameter of 0.165 inches.

Extrude the area in between the circles 0.471 inches

2. Select the end of the cylinder and create a 6 sided polygon with an apothem

of .1105 inches and a circle with a .139 inch diameterExtrude the area in-between the two sketches 0.092 inches

3. From the newly extruded side, create two concentric circles sharing a center the

center point with the hexagon. One circle with a diameter of 0.139 inches and the

other with a diameter of 0.165 inches.

Again select the area in-between and extrude 0.179 inches

4. Create a sketch on the YZ Plane. Select Project Geometry and select the outside

cylindrical surface is shown and draw what is pictured in 4.1 (The Project Geometry

tool is very useful. It takes a 3D edge or face and projects it to the current sketch.

This enables you to create precise sketches.) Select the coil feature under Part

Features select the object you made as the profile and for the axis select XZ Axis.

5. Now select the coil tab in the coil box. Under Type use the drop down to have it

read Revolution and Height. Make the height, 0.190 inches and the revolution 20.0

ul. Now click OK. You have just created a coil. NOTE: DO NOT USE THIS

FEATURE TO MAKE SPRINGS! THERE IS A SPRING GENERATOR THAT

CAN ONLY BE ACTIVATED IN ASSEMBLIES!

1: Create a rectangle with a length of 0.711 in and a width of 0.158 in, but use the line

feature and not the two point rectangle in order to insure that you will be able to alter

one line without changing the others. This step is shown in 5.1.

2: Shorten the left side of this rectangle to a length of .031in, as shown in the Picture 5.2

3: Draw a horizontal line off of the recently shortened side having a measure of .080, as

displayed in 5.3.

the part, create a new

line 0.011in off of the

base having a length of

0.055in. It should look

like figure 5.9.

10: Create another arc

between the horizontal

line underneath the first

arc and the line created

in the last step. Then

place a fillet with the

measure of 1.25 on this

new arc. This will look

like 5.10.
