You can visually identify the grounded components by their thumbtack icons displayed in the browser. Select the components either in the graphics or the browser, right-click, and choose Grounded. More than one component can be grounded and you can toggle between the components that are grounded. The first part inserted or created in the assembly is set as grounded by default in Autodesk Inventor. A part or assembly is considered grounded (fixed in space) when it has no DOF. The six DOF include three translational ones (linear along the x-, y-, or z-axis) and three rotational ones (angular along the x-, y-, or z-axis, as shown in Figure 1). All parts initially have six DOF without any assembly constraint. Let's first discuss the degrees of freedom (DOF) and how they impact assembly constraints. These constraints allow you to maintain the positions of components or their relations to one another in an assembly (such as two faces touching each other or a bolt in a hole). The way to assemble parts in Inventor is to use assembly constraints.
