The layers allow to assign properties to the objects and to control their visibility. It is possible to block the layers to impede modifying the objects
It is possible to reduce the visual complexity of a drawing and to improve its view controlling the visible or printed objects. As an example, it is possible to use the layers to control both properties and views of similar objects (e.g. electrical parts or quotations). It is also possible to block a layer, impeding the involuntary selection and modification of the objects present on it
It is possible to deactivate some layers in a drawing to hide them. This deactivation is very useful when working on a detail on a particular layer or group of layers; or even when deciding not to print some details (e.g. reference lines etc.)
Every layer has inherent properties (e.g. color, linetype) which are adopted by all the objects present on that layer. As an example, if the color control in the Property toolbar is set on BYLAYERthe color of new objects will be determined by the color setting in the Layer property Manager
If a specific color is set in color Control, this color will be used for all the new objects, ignoring the default color of the current layer. The same occurs for the linetype, line thickness and printing style controls, set on the Property toolbar.
Note: The BYBLOCK setting must be exclusively used for creating blocks.
When a layer is blocked, the objects contained in it will not be modifiable until the layer will be unblocked. The block reduces the possibility of accidental modifications to the objects present on the layer. It is anyway possible to apply snaps to objects contained in a blocked layer and perform other operations which do not modify those objects
