Digital Prototypes in

Autodesk Inventor

Autodesk Inventor®provides a comprehensive set of 3D mechanical CAD tools for producing,

validating, and documenting complete digital prototypes. The Inventor model is a 3D digital

prototype. The prototype helps you visualize, simulate, and analyze how a product or part

works under real-world conditions before it is built. Manufacturers get to market faster with

fewer physical prototypes and more innovative products.

Inventor provides an intuitive 3D design environment for creating parts and assemblies.

Engineers can focus on the function of a design to drive the automatic creation of intelligent

components, such as steel frames, rotating machinery, tube and pipe runs, electrical cables,

and wire harnesses.

Tightly integrated motion simulation and stress analysis in Inventor are easy to use. They

make it possible for engineers to optimize and validate the digital prototype.

Generating manufacturing documentation from a validated 3D digital prototype reduces

errors and associated engineering change orders (ECOs) before manufacturing. Inventor offers

rapid and accurate output of production-ready drawings directly from the 3D model.

Inventor is tightly integrated with Autodesk®data management applications. This integration

enables the efficient and secure exchange of digital design data and promotes earlier

collaboration between design and manufacturing workgroups. Different workgroups can

manage and track all components of a digital prototype with Autodesk®Design Review

software. This software is the all-digital way to review, measure, mark up, and track changes

to designs. You can better reuse crucial design data, manage bills of materials (BOMs), and

collaborate with other teams and partners.

Digital Prototype Workflow

Before you start a design, determine the most efficient workflow. A top down

workflow is often the most efficient way to create a design. In a top down

workflow, you design your components in the context of other components.

This method can greatly reduce errors in form, fit, and function.

Some examples of a top-down workflow are:

■Create new parts or sub-assemblies in the destination assembly.

■Create multiple solid bodies in a part file and then save the individual

bodies as unique parts.

■Create 2D sketch blocks in a part file to simulate a mechanism. You can

use the sketch blocks to create 3D components in an assembly that is

controlled by the layout.

Following are questions to consider before you start:

■Which view of the part best describes the basic shape?

■Is the part a sheet metal part?

■Can this part be used as a part factory (iPart) to generate multiple parts?

■Can a spreadsheet control one or more parts?

■Can I create the part automatically by using a Design Accelerator?

■If the part is a component in a structural steel frame, can I use Frame

Generator to create the entire frame?

■If the part is a common library part, does it exist in the Content Center or

other library?

The following image shows a multi-body part file saved as individual parts in

an assembly. Individual bodies in a multi-body part file can share features

with other bodies such as fillets and holes.

Components of Digital Prototypes (file types)

Create or activate a project file before you open an existing file or start a new

file to set the file location. Click New to see the New File dialog box with

templates for a new part, assembly, presentation file, sheet metal part,

weldment, or drawing. You can choose from several templates with predefined

units.

A template can contain property information, such as part and project data,

and drawing views. You can see information stored in a file by viewing its

properties.

For more information about templates, see Templates on page 67. For more

information about projects, see Projects on page 68.

For more information about projects, see Projects on page 68.

Part (.ipt) Files

When you open a part file, you are in the part environment. Part tools

manipulate sketches, features, and bodies which combine to make parts. You

can insert a single body part into assemblies and constrain them in positions

they occupy when the assembly is manufactured. You can extract multiple

part files from a multi-body part.

Most parts start with a sketch. A sketch is the profile of a feature and any

geometry (such as a sweep path or axis of rotation) required to create the

feature.

A part model is a collection of features. If necessary, solid bodies in a

multi-body part file can share features. Sketch constraints control geometric

relationships such as parallel and perpendicular. Dimensions control the size.

Collectively this method is called Parametric modeling. You can adjust the

constraints or dimensional parameters that control the size and shape of a

model, and automatically see the effect of your modifications.

The following image shows a single body part in the upper half of the image,

and a multi-body part in the lower half of the image. Notice the different part

icons in each image.

Assembly (.iam) Files

In Autodesk Inventor, you place components that act as a single functional

unit into an assembly document. Assembly constraints define the relative

position these components occupy with respect to each other. An example is

the axis of a shaft aligning with a hole in a different component.
