ATP 132 PART MODELING USING AUTODESK INVENTOR

Introduction

This course focuses mainly on 3D Part Modeling using AutoDesk Inventor. Generally Autodesk

Inventor is a Parametric Modeling tool. The latest release of AutoDesk Inventor is Autodesk Inventor

11.0 but in this course emphasis is given to the earlier package Autodesk Inventor 7.0 for beginners and

moreover the 3D Modeling concept in any version remains the same with addition of some commands in

the latest release. Here in this course the basics of 3D Part Modeling followed by examples are

explained.

About Part Modeling

In the latest release of Autodesk Inventor 11.0 there are a number of advanced modeling tools available

to carry out the Part Modeling as listed below

1) Extrude

2) Revolve

3) Fillet

4) Chamfer

5) Mirror

6) Hole

7) Circular Patter

8) Rectangular Patter

9) Thicken

10) Sweep

11) Decal

12) Loft

13) Coil

14) Shell

15) Rib

16) Thread

17) Face Draft

18) Split

19) Boundary Patch

20) Trim and Extend surface

21) Sculpt – NEW TOOL

22) Stitch

23) Delete - FACE

24) Move - FACE

25) Replace – FACE

Extrude: (+E)

For complete information about the Extrude Command see the

“ATP 120 Extrude Inside and out”

Revolve:

Part Feature > Revolve

Revolve Command helps in creating a revolved feature using one or more sketched profiles about an

axis

A typical revolve dialogue box is shown below

This consists of 2 entities

Profile

Axis

Profile: This command helps in selecting the profile drawn in the graphics area.

Note: If the profile has a single area then by default it is selected while if it’s a multiple area you will

have to select the profile button and then choose the area to be revolved

If by mistake you have selected the wrong area then press CTRL and then click on the profile to remove

Generally 3 types of profile is possible

Single

Multiple

Nested

AXIS: This helps in selecting the axis of revolution. The axis may be a work axis, a construction

line. Etc

Similar to that of Extrude Operation, Revolve has 3 operations

1) Join: adds the volume

2) Cut: removes the volume

3) Intersect: creates a new feature from shared volume

EXTEND: This helps in determining the angle of revolution. The values can be specified as Angle or

Full
