You can change the values in this window, or use the Select Edit tools and see the updated values in these fields.To replace a selected block with another block, select the replacement block from the list and click Replace with. Click OK to implement the change.

Inserting Blocks into Another File or Application
You can also use the drag-and-drop technique to insert blocks into another open file.Dragging a block into another drawing accomplishes two things: it inserts the block into the target drawing, and it places the block into the library of the target document. The target drawing must be open and its window must be visible on the screen. (Use Window / Tile to see all open windows.) After you drag the block, the target file becomes the active window.Drag-and-drop can also be used to place blocks, symbols, or any selected objects into other Windows applications, such as Microsoft Word or graphics programs.
Note: You can also use File / Extract To to export all blocks into another file.
