In the Import Block dialog box, search for and select the dwg file that contains the block definition. In the Block area, select the block you want to insert. Creating blocks in AutoCAD is very easy. First you must draw all the parts that will form your block.
Remember to draw all the objects on layer “0”. When you are ready to create the block, select the Create button from the Block section of the Insert tab of the ribbon menu. Groups have a bit of a similarity to blocks and can also be used in places where you want to create an object from various geometries. In the block editor, you'll also discover some extremely useful features, such as dynamic block attributes and functions, such as the base point, the extension, and more.
One configuration that caught my attention was the “Repeat placement” option, which allows you to place the selected block several times. In this case, simply modify the window block and all references used in the drawing will change automatically. A drawing made with blocks for repetitive objects will be much smaller than a drawing that uses copied instances of repetitive objects. Blocks are one of the most important types of objects in AutoCAD and are also used very frequently in almost all types of drawings.
When a set of objects is on layer “0” and you lock them, the new block will have the special feature of being able to change the color and line type of any layer where you place it. Once modified and saved, it will be automatically changed in the remaining blocks, since it is a single entity. A dialog box will appear that allows you to search for an external block that is in an external library. Recently, Sheen In Liew and Sophia Lee, from the AutoCAD team, organized a detailed webinar to help you learn how to work with blocks in AutoCAD.
You can also create your own tool palette and place your favorite CAD blocks on it, or you can create a complete catalog of your standard CAD blocks using tool palettes. There are also some useful block functions that you can find in AutoCAD Express Tools, which are only available in AutoCAD and not in AutoCAD LT. You can type the name of a block or select the drop-down list to see all the blocks available in this drawing. 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.
