Autodesk Inventor 2017 Tutorial: Mechanical 3D Design from Basic to Advanced

1. What is Autodesk Inventor 2017?

Autodesk Inventor 2017 is 3D mechanical design software developed by Autodesk, aimed at building highly accurate product models and managing the entire design process. The software allows users to start from a 2D sketch, develop it into a 3D detail, combine multiple parts into an assembly, and then create technical drawings for manufacturing. Unlike simple modeling, Inventor uses parametric modeling to maintain relationships between dimensions, geometry, and features. This is crucial when designing products that frequently change dimensions or have multiple versions.

• Create detailed 3D mechanical models.

• The design involves assembling multiple components.

• Create 2D technical drawings from 3D models.

• Designing sheet metal products.

• Create and manage dimensions and specifications.

• Check the relationships between the parts in the Assembly.

• Simulates the basic movement of the mechanism.

• Create multiple product variations based on the same design.

2. Why is Autodesk Inventor 2017 suitable for mechanical design?

Autodesk Inventor 2017's strengths lie not only in its 3D modeling capabilities but also in its design data management. Users can build products step-by-step, from initial sketches to complete models and fabrication drawings. For projects with frequent changes, parametric design significantly reduces manual editing. When a critical parameter changes, related features can be updated according to the established relationship.

• Parametric design: Easily resize without having to rebuild the entire model.

• Feature History Management: Track the detailed creation process and edit each step.

• Working with Assemblies: Combining multiple parts into a complete product.

• Creating technical drawings: Converting a 3D model into the necessary projections, sections, and dimensions.

• Sheet metal design: Assists in the construction of sheet metal components and workpiece development.

• Simulation: Examining the movement and interaction of components within a mechanism.

• Increased reusability: Old designs can be leveraged to develop new products.

3. Interface and key components in Autodesk Inventor 2017

When first opening Autodesk Inventor 2017, the interface might seem overwhelming for CAD beginners due to the sheer number of tools. However, if the interface is divided into distinct areas, getting familiar with it becomes simpler. Users primarily need to understand where to create files, the model manipulation area, the toolbar, and the Model Browser. The Model Browser is particularly important as it displays the model's structure. Sketches, features, and other components are arranged sequentially, making it easier for users to check and edit their designs.

• Ribbon: Contains command groups for Sketch, 3D Model, Assemble, Drawing, and other tasks.

• Model Browser: Displays the model history and structure.

• Graphics Window: The area where you can directly create and observe 3D models.

• Navigation: Supports rotating, zooming in, zooming out, and changing the viewing angle.

• Parameters: Manage the model's dimension parameters.

• Project: Manage the location and data structure of the project.

Step 1: Create a new project and design file.

First, open Autodesk Inventor 2017 and create a new project if you are starting a personal project. Organizing your folders from the beginning helps manage your Part, Assembly, and Drawing files more efficiently, especially when the product has many components.

Next, choose the file type appropriate for the task. If you're starting to build a single part, you can create a Part file. If you need to assemble multiple parts, the Assembly environment will be used in the next step. Choosing the right file type helps keep the design process clear as the project develops.

• Create a new project.

• Set the folder to save the data.

• Select New to create the file.

• Select the Part when creating the detail.

• Save the file immediately after starting.

Step 2: Create a 2D Sketch

Sketching is the foundation of much of the modeling process in Autodesk Inventor 2017. You start by selecting a plane such as XY, XZ, or YZ, then use the Line, Circle, Rectangle, and Arc tools to create 2D geometry.

After drawing the shape, use Dimension and Constraint to control the size and the relationships between the lines. A well-constrained sketch will make the model more stable when changing parameters. This is also an important step in getting acquainted with parametric design thinking.

• Select the Sketch plane.

• Create 2D geometry.

• Use Dimension to set the size.

• Add suitable Constraints.

• Check the Sketch status before finalizing.

Step 3: Create 3D details using Features

Once the sketch is complete, you can switch to the 3D Model environment to transform the sketch into a 3D model. The Extrude tool is one of the most basic commands, allowing you to stretch a 2D profile into a solid of a specified length.

After that, you can continue using other Features such as Revolve, Hole, Fillet, Chamfer, or Pattern to complete the details. Instead of trying to build the entire product at once, divide the model into logically structured Features. This makes editing easier later on.

• Extrude: Creates solid blocks or cuts objects.

• Revolve: To create a shape that rotates around an axis.

• Hole: Creating holes of various shapes.

• Fillet: Rounded edges.

• Chamfer: Beveled edge.

• Pattern: Duplicate a Feature according to a set rule.

Step 4: Edit parameters and manage Design Intent

One of the most valuable lessons to learn when using Autodesk Inventor 2017 is how to design models that are easily modifiable. You can open the Parameters to check the dimensions being used and adjust them as needed.

For example, instead of fixing all dimensions separately, you can create relationships between length, width, and distance. When the main parameter changes, the dependent components can update accordingly. This is how you can leverage the power of Parametric Modeling.

• Give names to the important parameters.

• Limit excess size.

• Use Constraint intentionally.

• Check the relationship between the features.

• Design according to the concept rather than just focusing on the final shape.

Step 5: Create the Assembly and assemble the parts.

After completing the individual parts, the next step is to create an assembly. This is the environment that allows you to combine multiple parts into a complete product and check how they fit together.

In Assembly, Constraints and assembly tools help define the relative positions of components. You can check if the parts are correctly positioned and detect any issues with spacing or movement before moving the design to the next stage.

• Insert parts into an assembly.

• Set the background details to fixed when needed.

• Use Constraint to link the components.

• Check the location and distance.

• Observe the movement of the appropriate mechanisms.

Step 6: Design the technical drawings.

A complete 3D model is not enough to put a product into production. Technical drawings help convey essential information such as dimensions, tolerances, materials, and machining requirements.

Autodesk Inventor 2017 allows you to create drawings based on 3D models. You can create master views, secondary views, cross-sections, and add dimensions. Because the drawing is linked to the model, when the design changes, much of the information on the drawing can be updated accordingly.

• Create a Drawing file.

• Choose the appropriate paper standard and size.

• Create a Base View.

• Add Projected View.

• Create Section Views when needed.

• Add dimensions and annotations.

• Review the drawing before exporting or printing.

Step 7: Familiarize yourself with Sheet Metal and its advanced features.

If you frequently design computer cases, metal enclosures, or sheet metal components, the Sheet Metal environment in Autodesk Inventor 2017 will make the process more convenient. Users can create sheet metal surfaces, bend edges, and unfold them into flat forms for machining.

Once you've mastered Part, Assembly, and Drawing, you can move on to exploring advanced features like iLogic, complex parametric design, library management, Frame Generator, or simulation tools. This is the stage where Autodesk Inventor 2017 performs better in large-scale mechanical projects.

• Set the sheet material parameters.

• Create flares and various curl shapes.

• Check the bending radius.

• Create a Flat Pattern.

• Export data for processing when needed.

• Learn about iLogic to automate repetitive tasks.

5. Recommended configuration for using Autodesk Inventor 2017

• CPU: Prioritize a processor with a good clock speed for smoother model manipulation.

• RAM: 8 GB can meet basic needs, while 16 GB is more suitable for frequent tasks.

• GPU: It is recommended to use a graphics card that provides good support for rendering 3D models.
