How to Create a Block in AutoCAD and Other Block Tips

A block is a combination of AutoCAD object types that make up a real-world object. For example, it could be a chair, manhole, door, utility pole, you name it.To get more news about download cad, you can visit shine news official website.

Looking to learn how to create a block in AutoCAD? There are a few ways to do it. Here, we’ll discuss different ways to make a block as well as some tips to get blocks to do what you want.
Let’s say we want to make a symbol for a telephone manhole from a bunch of CAD objects. And, on top of that, the manhole may be used to show that it is existing or that it is proposed, and they each need to look like the following image on the right.

You could make two blocks each with their own layer properties—or you can leverage a really cool functionality in AutoCAD.

First, everything in AutoCAD goes on a layer and has object properties (e.g., color, linetype, lineweight, etc.), and this includes blocks. That said, the objects “inside” the block can also go on their own layers. If you make a block of objects on their own unique layers, AutoCAD “locks in” what layer those objects are on. No matter what layer the block is on, none of the AutoCAD objects will look like the properties of the block.

And this is where layer 0 comes in. You can leverage this cool feature in AutoCAD where any objects that are on layer 0 (and set to ByLayer) and are in the block will take on the blocks layer properties. Now, understanding this functionality, let’s make one block called Telephone Manhole.

To use the layer 0 functionality in your block, let’s first set all the objects to layer 0 and set the properties to ByLayer.

Type “B” in the command line to open the Block Definition dialog box. Starting from left to right, give the block a name.

Now, you need to tell AutoCAD what the insertion point should be. In other words, when you place the block, the point about which the block appears at your cursor.
Be aware of the Block unit setting. AutoCAD has no idea what units in which you created the object; here is where to say what it is. Setting this will allow you to insert the block into other drawings with different units and to scale automatically.

If you have multiple block instances in the drawing, the objects inside the block will take on the block’s layer properties for whatever layer each block is on. Here, the block on the left is on the layer ManholeTel_ep (existing) and the block on the right is on layer ManholeTel (proposed). Notice the grip at the center of the block. This is the insertion point that is defined.
