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. CAD blocks are called groups of objects that act as a single 2D or 3D object. You can use them to create repeating content, such as drawing symbols, common components, and standard details.
Blocks help you save time, maintain consistency and reduce file size because you can reuse and share content. A block is a combination of AutoCAD object types that form a real-world object. For example, it could be a chair, a sewer, a door, a utility pole, you name it. This means that you can modify (move, copy, rotate) a block by selecting only one object in it.
You can create a block library made up of the pieces you need many times in your workday. These blocks can be stored in a separate folder and even on a network so that all writers have access to them. Think of plumbing parts, valves, elbows, etc., as well as electrical symbols or furniture. The basic use of the block is as reusable content.
You can define a block once and then use it repeatedly without redrawing it in new drawings or in the same drawing. You can choose to copy the objects. But when the drawing gets complicated, this can be a difficult task. If you draw it more than once, you might want to consider creating a block from it.
The blocks of AutoCAD, or those of any other CAD program, are files that can be inserted into other CAD files, it's that simple. Next, we'll share some of the key ideas from this tutorial on autocad blocks along with links that will take you directly to the topic and continue with the webinar video. You can take advantage of this fantastic feature of AutoCAD, where any object that is in layer 0 (and configured as ByLayer) and is in the block will acquire the properties of the block layer. You can create two blocks, each with its own layer properties, or you can take advantage of some really interesting functionality in AutoCAD.
If you create a block of objects on your own unique layers, AutoCAD “locks the layer where those objects are located”. AutoCAD and the suite of architectural tools help the company design an independent and assisted living community in which quality of life is paramount. 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. A landscape designer shares the inspiration to start her own business and how AutoCAD LT helps her succeed in the design process.
A one-woman interior design company takes advantage of AutoCAD's skills to serve clients and other interior designers alike. In the video you'll find great tips and step-by-step instructions on how to save a block in AutoCAD. 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. When you insert a block, AutoCAD stores only the name of the block, its location (insertion point), scale, and rotation.
