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).
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.
Can you delete Layer 0 in AutoCAD?
The following layers cannot be deleted: Layer 0 and Defpoints. The current layer. Layers containing objects.
What is the purpose of layers in AutoCAD?
The layering system is an essential drawing management in AutoCAD, and you should use layers in every drawing. The common usage of layers is to draw objects on a layer based on their function. Create all dimensions on a specific layer. Create walls, doors, windows on separate layers, and so on.
What layer should blocks be created on?
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.
Why would you draw blocks on the 0 layer?
Why would you draw blocks on layer 0? If created on layer 0, the block assumes or inherits the properties of the layer on which it is inserted.
What is the purpose of locking a layer?
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. Objects on locked layers appear faded and a small lock icon is displayed when you hover over an object on a locked layer.
How do I remove a Defpoint layer?
Hello, 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?

What are AutoCAD layers?
AutoCAD layers are a bit like transparent overlays. You can create as many layers as you like. You can use layers to control the colour, line type, line weight and plot style for your geometry (amongst other things) as well as the visibility of all the geometry on that layer.
What is the layer?
(Entry 1 of 2) 1 : one that lays something (such as a worker who lays brick or a hen that lays eggs) 2a : one thickness, course, or fold laid or lying over or under another. b : stratum.
What are layer controls?
The Layer Controls effect allows you to set the control of a layer through expressions, which can be a really useful thing. The Layer Control has been a bit of a mystery that is kept under the expressions controls section of the effects menu in After Effects.
What is 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.
What is by block in AutoCAD?
06-02-2010 12:50 AM. 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 ByBlock?
ByBlock is the first construction-grade building material made entirely from recycled (and often un-recyclable) plastic waste.
