Place Component Plus
This add-in adds a button to the drop-down list under the Place button that allows you to choose a component, that is currently open in Autodesk® Inventor®, from a list and place it into your active assembly.
In the Place Open Component Dialog box, you can either select the component and then click the Place in the Assembly button, or you can just double click on the component you want to place and it will place it into your assembly. To make selecting the right component easier, the dialog box will display a thumbnail preview of the component when it is selected.
This add-in requires you to be logged in to your Autodesk Account in Inventor.
