Identifying Inventor Files

The files created in different environments (Part, Assembly, Drawing, and Presentation) of Autodesk Inventor have different file extensions, see the table given below:

Creating a Project

In Autodesk Inventor, you can create a project for organizing, accessing, and saving all the files such as parts, assemblies, drawings, standard components, library components, etc. that are associated with a particular design. You can define any folder created in a local drive of your system or in a vault as the project folder for saving all the files of a particular design in a common location, making it easier to manage all the files of the project. The method for creating a project is discussed below:

1. Click on the Projects tool in the Launch panel of the Get Started tab, see Figure 1.35. The Projects dialog box appears, see Figure 1.36. The upper half of the dialog box displays a list of already created projects. The Default project is created, by default.

Autodesk Inventor is a feature-based, parametric, solid modeling mechanical design and automation software. Before you start creating the solid 3D components in Autodesk Inventor, you need to understand it. To design a component in this software, you need to create all its features one by one, see Figures 2.1 and 2.2. Note that the features are divided into two main categories: Sketch based features and Placed features. A feature created using a sketch is known as Sketch based feature, whereas a feature created on an existing feature without using a sketch is known as Placed feature. Of the two categories, the Sketch based feature is the first feature to be designed for any real world component. Therefore, it is important to first learn drawing a sketch.

Figure 2.1 shows a component consisting of an extrude feature, a cut feature, a chamfer, and
