Click Blocks from Libraries.
From any tab in the Blocks palette, click Insert DWG as Block ().

Use either the click-and-place or drag-and-drop method to insert the DWG as a block into the current drawing.
At the bottom of the Blocks palette, choose one or more options to control the placement, scale, rotation, and automatic repetition. If you want the objects in the block to be inserted as individual objects instead of as a single block, select Explode.
