This page describes the concept of “Features” in Inventor Fusion. A Feature in Inventor Fusion is essentially a collection of faces that represents a shape corresponding to a mechanical feature.

This page describes the concept of “Features” in Inventor Fusion. A Feature in Inventor Fusion is essentially a collection of faces that represents a shape corresponding to a mechanical feature. Inventor Fusion uses the Direct Modeling paradigm as opposed to the Parametric Modeling paradigm used by Inventor.

As a result, the concept of a Feature in Inventor Fusion is a little different. The main differences are:

1 Features in Inventor Fusion are not “ordered”, in that the order in which they are created and represented in the browser does not affect how the model behaves under further operations.

2 A feature created in Inventor Fusion exists only as long as it is “valid”, for example, the shape defined by the feature conforms to the definition of the feature. If you create an Extrude feature and then tweak one of the faces created by the Extrusion using the Move command such that the Extrude is no longer valid, the Extrude feature ceases to exist.

3 Features in Inventor Fusion that offer the Edit function are edited “directly”, for example, editing the feature does not cause a cascading effect on other features in the model as it would in a history-based modeler.

Inventor Fusion provides the following Features:

■ Extrusion

■ Revolution

■ Sweep

■ Loft

■ Hole

■Fillet

■ Chamfer

■ Shell

■ Rectangular Pattern

■ Circular Pattern

■ Mirror

Of these, Extrusion, Revolution, Sweep and Loft are Sketched Features. They are created from one or more 2D sketches on page 135.

Each Feature is created by a command that allows the user to provide the inputs necessary to create the Feature using the direct manipulation user interface.

Features can also be created on an imported model by using the Find Features on page 181 command.

Once a Feature is created, it is represented in the browser under the Component. A Feature can be selected by clicking on the browser or by selecting one of its faces and using the Select Other on page 18 command. Once a Feature is selected, it can be deleted by using the Delete command.

Features can be patterned on page 178 using the Rectangular Pattern or Circular Pattern commands. Some Features provide an Edit command, which allows the Feature to be edited in place. The following Features provide an Edit command:

■ Hole

■ Fillet

■ Chamfer

■ Rectangular Pattern

■ Circular Pattern

When a Feature is edited, the same direct manipulation interface as the one that is used to create the Feature is made available to the user to modify the input parameters of the Feature.
