To use this block in the drawing area, follow these instructions:

1. Click the Insert option in the Block panel and there you will see a preview of the block you just created.

3. Click on any point in the drawing area to insert the block, as shown:

You can also make copies of existing blocks from your drawing and you will still end up with references of the block. If you make more blocks, they will be added to the block library, just like the door blocks, and you can use them by clicking the Insert option of the Block panel.

To see a list of recently used blocks and to access more options while inserting blocks, click the Recent Blocks... option in the Insert panel. The Blocks panel, with the three Current Drawing, Recent, and Libraries tabs, will show up, as shown:

Click on the Current Drawing tab and the panel on the right will show all the blocks in the current drawing. You can change the way the blocks are visible in the panel using the preview option, as in the previous figure.

To insert a block from this panel, just click on it and then click in the drawing area to insert the block. The block will be added with its base point on the cursor. You can also drag and drop blocks from the preview area to the drawing area.

All the recently created, modified, or inserted blocks will show up in the Recent tab and you can use this as a filter to sort through the big list of blocks and access the blocks that you have recently used.
