For AutoCAD® 2015-2017. Press Ctrl+3 to open Tool Palettes. Right-click on the bar with palettes' names and select AutoFurniture. Drag a block from the AutoFurniture tool palette and drop it in your drawing. Use the block's dynamic grips as shown in the videos. 

For all releases of AutoCAD and Autodesk® AutoCAD® Architecture. Click the AutoFurniture icon in the Add-Ins ribbon tab to open AutoFurniture_v1.0.dwg in the Design Center, drag a block from the DesignCenter window and drop it in your drawing (or copy a block from C:\ ProgramData\ Autodesk\ ApplicationPlugins\ AutoFurniture.bundle\ Contents\ AutoFurniture_v1.0.dwg and paste it into your drawing). Use the block's dynamic grips.

The installer that ran when you downloaded this app/plug-in from the Autodesk App Store will start installing the app/plug-in. OR, simply double-click the downloaded installer to install the app/plugin. You may need to restart the Autodesk product to activate the app/plug-in. To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button. OR, click Control Panel > Programs > Programs and Features (Windows 7/8.1/10/11) and uninstall as you would any other application from your system.

The order of a block inserted from the Tool Palette or from the Design Center may be disrupted. If so, copy all the blocks from C:\ ProgramData\ Autodesk\ ApplicationPlugins\ AutoFurniture.bundle\ Contents\ AutoFurniture_v1.0.dwg and paste them into your drawing (if a damaged block has been already inserted, erase it and purge your drawing first.) Once the right block definitions are imported in your drawing you can use the Tool Palette and the Design Center as usual.
