The BYLAYER setting for block components means - inherit the properties from the layer the block is inserted in. The BYBLOCK setting for block components means - inherit the properties from the properties of the block (the block reference/insertion). So if you have e.g. a block inserted in the layer LAY (colored green) and you assign it ( Ctrl+1) the color red, a line (in the block) with the color BYLAYER will be green and a line with the color BYBLOCK will be red.
What is the difference between byblock and bylayer?
If the properties of objects within the block are set to Byblock and the properties of a block is set to Bylayer, then the properties of objects in the block will change with the inserted layers, we could directly modify the block properties to control the properties of objects within the block.
What is the difference between layer and bylayer in AutoCAD?
Bylayer: inherit the properties from the layer the block is inserted in. Objects are Bylayer by default. Layer is a useful tool to manage graphics and graphic objects in the same category will be put on one layer, so using the properties to control graphic objects is more convenient.
What is the difference between a layer and a block?
We can clearly see the layer where separate objects are on. The layer where objects in the block are on is related to both the layer when we define graphics as blocks and the layer when we insert block reference.
What are the default properties of a byblock object?
But if the properties of the graphic objects have been set to Byblock without being defined as a block, then the graphic objects will use the default properties: the color is written, the line weight is 0, the linetype is a full line.
What is ByLayer and Byblock in AutoCAD?
If the properties of objects within the block are set to Byblock and the properties of a block is set to Bylayer, then the properties of objects in the block will change with the inserted layers, we could directly modify the block properties to control the properties of objects within the block.
What is ByLayer AutoCAD?
The definition of by layer is that an objects color, line weight, and line type properties are determined by the settings assigned to the layer, and not by the objects individual settings. If an object is placed on a layer that is assigned the color green, the active color property is set to by layer.
How do you use ByLayer in AutoCAD?
Changes the property overrides of selected objects to ByLayer. You can specify which properties are changed to ByLayer, including color, linetype, lineweight, and materials. The following prompts are displayed.
What is ByLayer command?
The Set to ByLayer command sets properties of selected entities to ByLayer. Properties that can be changed using the Set to ByLayer command include: color, linetype, lineweight, material, print style, and transparency.
Where is ByLayer in AutoCAD?
The Object Properties toolbar displays the current layer information. In the illustration above, you can see that layer "0" is the current layer and that both the colour and linetype are set "ByLayer". When you start a new drawing, AutoCAD has only one layer. This layer is special and is called layer "0" (zero).
What is a Defpoint 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 are frozen layers in AutoCAD?
You can freeze layers to speed up zoom, pan, and many other operations; improve object selection performance; and reduce regeneration time for complex drawings. AutoCAD does not display, plot, hide, render, or regenerate objects on frozen layers. Freeze the layers you want to be invisible for long periods.
How do I change the ByLayer in AutoCAD?
Use the SETBYLAYER AutoCAD command to quickly change block object properties to Color=ByLayer. Type in Setbylayer at the command prompt: Or on the Home Ribbon on the Modify tab: Select the Settings option to verify that Color (and if needed Linetype, Lineweight, Material, Plot Style and Transparency) is selected.
Should you draw on the 0 layer explain?
Should you draw on the 0 layer? Explain. Answer: No. The 0 layer is primarily reserved for drawing blocks.
What is the difference between layer freeze and layer off?
When a layer is frozen, AutoCAD releases it from memory and no longer has to account for it during a regeneration. To help with performance, freeze the layer and keep in mind that the layer will no longer be seen. If the layer is supposed to be temporary unavailable on the screen, turn the layer off.
Can we delete layer 0?
The following layers cannot be deleted: Layer 0 and Defpoints. The current layer. Layers containing objects.
How many layers are there in AutoCAD?
Unlike other "CADs" with a limit of 64 layers (even limited to numeric names), AutoCAD can work with virtually unlimited number of layers - you can have tens of thousands layers in a single drawing.
How do I change the ByLayer in AutoCAD?
Use the SETBYLAYER AutoCAD command to quickly change block object properties to Color=ByLayer. Type in Setbylayer at the command prompt: Or on the Home Ribbon on the Modify tab: Select the Settings option to verify that Color (and if needed Linetype, Lineweight, Material, Plot Style and Transparency) is selected.
What is the purpose of layer 0 in AutoCAD?
Layer 0 has special importance to blocks. When objects assigned to layer 0 are used as parts of a block and that block is inserted on another layer, those objects take on the characteristics of their new layer.
Can layer 0 be deleted in AutoCAD?
The following layers cannot be deleted: Layer 0 and Defpoints. The current layer. Layers containing objects.
What does it mean to thaw a layer in AutoCAD?
Using this command, you can make layers that display in one or more viewports invisible in other viewports within the same drawing. The terms freeze and thaw are used in conjunction with this command to mean the visibility or invisibility of a layer in a drawing.
When you insert a block in AutoCAD, what layer will it use?
When you insert AutoCAD blocks, they will use active layer. Every objects in block that use Layer 0 will use the block layer properties. When you define object properties (color, line weight, etc) to ByLayer, all of it properties will use the same properties as it’s defined in the layers’ properties. When you create geometries in your AutoCAD block ...
What is the default layer in AutoCAD?
Every time you create a new AutoCAD drawing, you will see a default layer: Layer 0. This layer can’t be deleted.
Why did block 4 disappear in Layer 1?
Now freeze Layer1. We can see the block no. 4 disappeared, because the object in it was created on it.
How to make two layers in AutoCAD?
Open your AutoCAD, in a new file create two layers, you can give them any name. Set different color and lineweight so we can easily distinguish them later.
How many blocks can you make from each circle?
Create 4 blocks from each of the circle.
Can you override a block in AutoCAD?
When you create geometries in your AutoCAD block other than ByLayer or ByBlock, then you can’t override them after your block has been placed.
What is bylayer in graphics?
Bylayer is simple, the properties of graphic objects will inherit the properties of the layer they’re on no matter the objects are separate or in the block. We can clearly see the layer where separate objects are on. The layer where objects in the block are on is related to both the layer when we define graphics as blocks and ...
What is a bylayer?
Bylayer: inherit the properties from the layer the block is inserted in.
What layer are graphics objects on?
The layer where objects in the block are on is related to both the layer when we define graphics as blocks and the layer when we insert block reference. If the graphic objects are on layer 0, after being defined as a block, the graphics objects will be on the layer where the block is inserted.
What happens when you set a graphic object to Byblock?
After the graphic objects are defined and set to Byblock, we can modify the properties of the block and the properties of the objects will change according to the block. But if the properties of the graphic objects have been set to Byblock without being defined as a block, then the graphic objects will use the default properties: ...
What happens if a block is not byblock?
If the properties of graphic objects within the block haven’t been set to Byblock, then modifying those blocks will make their properties remain. For example, set the color of a circle as red and define this circle as a block, then change the circle to green, the circle will remain red.
What are the attributes of CAD?
Objects in CAD have several basic attributes such as color, linetype, line weight and so on, these attributes control the display effect and printing effect of graphics. So setting attributes of objects properly can make graphics more clear, more importantly, we can get the best printing effect. When setting the color, linetype and line weight of the objects, we can see the two options of Byblock and Bylayer in the list. However, even people with some CAD knowledge could be confused by them, not mention how confusing they can be to CAD newbies.
Can bylayer change properties of blocks?
If the properties of objects within the block are set to Byblock and the properties of a block is set to Bylayer, then the properties of objects in the block will change with the inserted layers, we could directly modify the block properties to control the properties of objects within the block. If the properties of objects in the block is set to bylayer or other fixed properties, then changing the block properties won’t affect objects in the block.
What is Byblock settings?
If some flexibility is required for blocks without creating additional layers, then Byblock settings can be used to change how a block looks without placing it on a different layer.
What are the properties of AutoCAD?
Every object has general properties including layer, colour, linetype, linetype scale, lineweight, transparency and plot style.

I've been reading up on a lot of things since my last post. I've became a lot better at 3D and now I even understand what layout1 and layout2 are for (mostly). The difference in model space and paper space.
Berzerker
OK great now I don't feel so dumb that I've never used it. Yeah good layer discipline was not something I had till Cad64 helped me out. Thanks Cad64!

No Prob. I was trying to work in the word 'hole' but couldn't come up with an analogy. LOL
Dana W
Truthfully I don't know what By Block actually does. It has something to do with how objects in a block behave as far as inheriting the properties of the layer it gets inserted upon.
Berzerker
The term he ( the guy that said it first) used way back then was "It's like cutting a hole in a piece of paper and looking through it at your drawing"
CyberAngel
There is no reason, 9,999 times out of ten thousand, to use anything but ByLayer for color. When you use ByLayer, you can redefine the color of the layer, and that changes all the objects on that layer that have the Bylayer color. If an object's color is defined as something else, it won't change.
RobDraw
Color and linetype overrides are used a lot more than you think, especially within blocks. Some standards use layers for object grouping and have overrides for printing purposes that deviate from the layer properties.
