This option is only useful when creating blocks.

If an object's properties are By Parent, the object will continue to draw as if set to By Layer. However, when the object is part of a block, it takes on the properties of the block instance (layer or property).

Example using By Parent color:

  1. Make a layer called Red, and set its color to red.

  2. Draw a circle on layer Red.

  3. Select the circle, and set its color property to By Parent.

    The circle will still be red.

  4. Select the circle and use the Block command to turn it into a block.

  5. Make a layer called Green, and set its color to green.

  6. Make Green the current layer.

  7. Insert the block from step 4 on layer green.

    The circle will be green because the block instance is on layer Green, and the block's color property is "By Layer."

  8. Select the block instance, and set its color property to blue.

    The circle will be blue because the block instance's color property is set to blue.

    Note for nested blocks: Blocks made of nested blocks that include objects set to the By Parent color, are not affected by further nesting.
