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.
Considering this, 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!
Correspondingly, 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).
Subsequently, 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, should you draw on Layer 0 explain? Should you draw on the 0 layer? Explain. Answer: No. The 0 layer is primarily reserved for drawing blocks.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 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 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 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?
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. All objects of the selected layer will be deleted and the layer will also be purged.
How do I delete an empty layer in AutoCAD?
Pick the layer, right click, pick delete layer. You can sort the status column by picking on Status, pick a layer, hold Shift, move down and pick another layer, all those layers are selected, right click and pick delete layer.
What is the difference between the redraw and Regen commands?
Redraw refreshes the current view. REGEN regenerates the entire drawing and recomputes the screen coordinates for all objects.
What is the default linetype in AutoCAD?
When you first start AutoCAD, the default template has only one linetype is available. This is the continuous linetype. AutoCAD has many more available, but only loads in one to start with in order to keep the drawing file size smaller. If you need a different linetype, you must load it into your current drawing.
What is the purpose of locking a layer?
You can prevent objects on specified layers from being selected and modified by locking those layers. When a layer is locked, none of the objects on that layer can be modified until you unlock the layer. Locking layers reduces the possibility of modifying objects accidentally.
