How to create a layer in autocad

What is the 0 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. How do I change the Defpoint layer? Layout viewports are objects that display views of model space.

You create, scale, and place them in paper space on a layout. On each layout, you can create one or more layout viewports.

Each layout viewport is like a closed circuit TV monitor of a view of the model at a scale and orientation that you specify. Layers are the primary method for organizing the objects in a drawing by function or purpose.

Click the location that you want to identify. The X,Y,Z coordinate values are displayed at the Command prompt. Click Set Current. Change the Properties Assigned to Layers If you want to change multiple layers, use one of the following methods in the Layer Properties Manager: Press and hold Ctrl, and choose several layer names. Press and hold Shift, and choose the first and last layers in a range. Right-click, and click Show Filters in Layer List. Choose a layer filter from the list of layers.

Click the current setting in the column that you want to change. Choose the setting that you want to use. Layer 0 cannot be deleted or renamed to ensure that every drawing includes at least one layer. In general, you should always create several new layers with which to organize your drawing, rather than create your entire drawing on layer 0. Layers are the primary method for organizing the objects in a drawing by function or purpose. Since the layer 0 is default layer and always available, the minimum allowable number of layers is 1.

Use layers to control the visibility of objects and to assign properties such as color and linetype. Objects on a layer normally assume the properties of that layer. However, you can override any layer property of an object. Layers contain the images, text, or objects that make up a layered file. They let you move, edit, and work with content on one layer without affecting content on other layers.

Click the layer name or press F2. Enter a new name. Click Delete Layer. The following layers cannot be deleted: Layers 0 and Defpoints Layers containing objects, including objects in block definitions The current layer Layers used in an external reference Note: To remove all unused layers, use PURGE. Click Set Current. Change the Properties Assigned to Layers If you want to change multiple layers, use one of the following methods in the Layer Properties Manager: Press and hold Ctrl, and choose several layer names.

Press and hold Shift, and choose the first and last layers in a range. Right-click, and click Show Filters in Layer List.
