A quick way to create a block in AutoCAD First, press CTRL+SHIFT+C on the keyboard and then adjust the cursor to the “insertion point” where you want the block to be defined. Then, select the objects from which you want to create a block and press ENTER. In the context of AutoCAD, blocks are the set of geometries that act as a single object and can be used in a drawing on a repetitive basis. The blocks used in the drawing are called block references, and if the block is modified, all of its references change automatically.
Is there a way to add an image to the block's block file? So that when you are searching for blocks you can directly see the image of the block. You can access that block from other drawings using DesignCenter or Content Explorer, but you probably need to remember where the block was to find it. If you're not using blocks in your drawings, you'd better start soon because you're missing out on some of the incredible advantages of AutoCAD blocks. As I mentioned earlier, one of the main reasons for using a block is its ability to modify all of its references by modifying a single block.
For example, you can create a dynamic block of a door of different sizes and, when used in the drawing, you can use the same dynamic block for all door sizes. Because you assign names to these drawings and store them especially so that they are easier to find and identify, the blocks they contain are easier to find. In this case, simply modify the window block and all references used in the drawing will change automatically. Attributes are information such as the manufacturer's name, part number, etc., that is associated with a block and can be extracted to an Excel file or drawing table.
AutoCAD has a small library of some standard blocks that you can use in your drawings. This block library can be accessed from the Design Center palette.
