Layer 0 is a default AutoCAD layer. When you want to create geometry for blocks, this is default layer for it. When you insert AutoCAD blocks, they will use active layer. Every objects in block that use Layer 0 will use the block layer properties.
As many you asked, what is the zero layer in AutoCAD? The layer 0 (zero) is the default autocad layer that exists for creating blocks with. So when that block is inserted (or placed) on another layer, it takes on the properties of that layer (depending on our geometry properties: ByBlock and ByLayer etc). There may be more reasons for this layer but that’s the biggie!
You asked, should you draw on the 0 layer in AutoCAD? The only thing that Layer 0 should be used for is for creating blocks. afterwards (without exploding the block).
Likewise, can you delete Layer 0 in AutoCAD? Layer 0 and Defpoints cannot be removed from drawing. It’s impossible. They are in every drawing. Currently active layer can’t be removed.
You asked, what is layers levels in AutoCAD? Layers organize your drawing, enabling you to temporarily suppress the display of unneeded graphical data. You can also assign default properties such as color and linetype to each layer.Layer Setup Right click on a layer definition and choose Rename Layer. Change the layer names to match the equivalent AutoCAD layer name. For example: rename AM_5 to Dimensions. Make any desired changes to the colors, linetype or line weight settings as well.

What is the advantage of creating a block in zero layer?
If the entire apartment as a Block is Inserted on that Layer, all of it, including all pieces on all nested Layers, will disappear when that Layer is Frozen. If it’s on Layer 0, you can do whatever combinations you like of control of the other Layers, without risk of losing visibility of the whole apartment.
What is the difference between Bylayer and Byblock in AutoCAD?
As you know BYLAYER means an object will get its property from the value assigned for that property to the layer. BYBLOCK however applies specifically to the elements of a block. The attribute value of the element is the one assigned to the block. For example.
What does Byblock mean?
If you want to control the appearance (colour) of some part of the block, you can assign the ByBlock value to that part of the block, which really means that this part of the block doesn’t have any value assigned until it’s inserted in drawing.
What is AutoCAD Defpoints layer?
The Defpoints Layer is a standard system layer used by AutoCAD and IntelliCAD. When you create dimensions in IntelliCAD or AutoCAD, the dimensioning components such as extension lines, arrowheads, dimension lines, and dimension text are placed on the current layer.
How do you delete a layer 0?
- Enter LAYDEL on the command line.
- Click ‘Name’ or enter N.
- Select the Layer and click ‘OK’ to delete it.
How do I clean up a layer in AutoCAD?
- Click the Application button Drawing Utilities Purge. The Purge dialog box displays a tree view of object types, called named objects, with items that can be removed from the drawing.
- To purge unreferenced layers, use one of the following methods:
- Click Purge.
How do I delete unused Layers in AutoCAD?
To use this command type LAYDEL on the command line and press enter, your command line will show this message. Select an object on the layer which you want to delete from drawing area and press Enter then select Yes from command line options and press enter again.
What are the layer properties?
Layer properties are settings that can have a list of different values for a display characteristic. The following properties can be set for a layer in the Layer Properties Manager: Color: Changes the color of objects on the layer. Clicking the color name displays the Select Color dialog box.
