Autocad Layer | Autocad select all in layer | Autocad layer standards | Autocad layer states | Isolate layer AutoCAD
Previously we saw almost all command from the Draw panel and Modify panel. Earlier we learned how to use Hatch and Gradient in AutoCAD.
Now we will learn the most important command, the Layer command. So, let’s get started.
Before going to the Layer command, we need to go to the ‘Properties’ tab. When we draw any object, its properties like line type and line color will be shown there. But by default, it will be shown as ‘By layer’.
But what is ‘By Layer’? Let’s know about that.
What is the Layer command?
Simply we can define layer as a group of objects. Layers are the basic method for organizing the objects in a drawing by function or purpose.
In an architectural drawing, we are creating a foundation, floor plan, door-windows, furniture, text, and so on. So, to reduce the complexity of the drawing at the time of the editing, we can draw all these elements in a particular group. For example, one group (Layer) of foundation, second group (Layer) of the wall, the third one of furniture, etc
Advantages of using layer command:
1 Layer command saves too much time.
2. We can change the color of the whole layer. So we can change the colors of many objects at once which are included in that layer.
3. Similarly, we can also change line type of layer.
4. At the time of editing, we can hide unnecessary objects by hide layers.
5. We can also freeze and lock layers.
6. We can find out the particular object of the big drawing by short-out the particular layer by its name.
How to use Layer command?
We should prepare every drawing by making layers. So we can edit and control our drawing very easily.
Before starting drawing, we need to create layers that will be useful in the drawing. Or at least make layer every time when you draw some new thing in the drawing.
First of all, Double click on the ‘Layer properties’ or type ‘LAYER’ in the command bar.
Then create a layer and make that layer the current layer. So every object will be drawn in that layer.
If you are drawing the wall at first, make the first layer of the wall layer. And after walls, if you want to draw windows and doors then make the second layer of door-window and after that draw door-window.
Let’s learn about the functions of the layer properties.
Properties of the Layer command:
1) New Layer (Alt + N):
The new layer creates a new layer immediately and can change the name after creating. The new layer is creating according to the currently selected layer. This means it will the same as the current layer’s color, on/off state, line type, etc.
2. Current layer (Alt+C):
It makes the selected layer a current layer. Makes a green check-mark on the selected layer. After creating a new layer, it is necessary to make the created layer as a current layer. So, which object will you draw, it will be in the current layer.
Just select the layer you want as a current layer and click on the Current layer icon.
We can also double-click on the layer to make it current.
3. Make current:
The Short-cut key is ‘LAYMCUR’. This is another way to make the current layer without coming in the ‘Layer properties’ when the objects are already drawn. By using this command, we can directly make the current layer by only selecting one object of the layer.
Click on ‘Make current’ and click on any one object of the layer. That selected object layer will be the current layer.
4. New layer VP frozen
You can see here new layer VP frozen creates a new layer but freezes it in all layout viewports.
5. Delete layer (Alt + D):
Delete layer deletes unwanted layers created by us. We can’t delete the reference layer which is ‘Layer 0’ and ‘def points’ because of the default layers.
Just select the layer you want to delete, and click on the delete layer icon.
6. New group filter (Alt + G):
It creates a new group. In a big drawing, there are different floors in the architectural plan. We can make a group of a layer of each floor. Like the ground floor, first floor, etc.
7. New property filter (Alt + P):
By clicking on this, we can very easily find any group or any layer by filtering.
We can change the color of all layer objects very quickly by changing the color here.
We can change the line type of all layer objects from continues to another as per requirement. To change the line type, click on the ‘Continues’ and load the lines.
Select line type as per requirement and select and ‘Ok’. Linetype will be applied to all objects of the layer.
We can change the thickness of all object lines of the layer by changing the line weight from here.
We can decrease the transparency of all objects of the selected layer by changing the transparency number from 0 to 90.
It controls layer to visible in printing or not. If the layer is off or frozen, a layer will not plot in the printing. If printing is off, we can see the object in the model space, but can not see in the paper space.
13. On/Off state
The Short-cut key is ‘LAYOFF’. It controls the visibility of the object. We can hide unwanted layer objects by On/Off state as per requirement. Just click o that icon layer will be On/Off.
14. Turn All Layers On
The Short-cut key is ‘LAYON’. It turns on all layers of the drawing. If you have off too many layers and you want to on all layers then it is very useful.
The Short-cut key is ‘LAYFRZ’. It freezes the layer. The freeze means it makes invisible the layer the same as the On/Off. When the layer is freeze, we can not see the object of the layer in the model space as well as paper space.
But the difference in the On/Off and Freeze is when the object is off, and we select all commands by ‘Ctrl+A’ the Off layer will select.
But when we freeze the layer, It will not select ‘Ctrl+A’.
16. Thaw All Layers
The Short-cut key is ‘LAYTHW’. It is unfrozen all layers.
17. Lock Layer
The Short-cut key is ‘LAYLCK’. By locking layer, we cannot do anything on that layer. Even we cannot select a locked layer. By using this layer, we can prevent objects on a layer from being accidentally modified.
18. Unlock Layer
The Short-cut key is ‘LAYULK’. By unlocking the layer, we can select the object and modify it. In this layer, no need to select a layer to unlock. We can unlock the layer by object selecting without specifying the layer name.
19. Isolate Layer
The short-cut key is, ‘LAYISO’. By using the Isolate layer, we can turn off all commands except one layer on which you want to work. If you want to work only on the wall layer, then you can hide all other layers except the Wall layer.
Select Layer Isolate, and select one object of the layer you want visible.
Go at the setting in the command bar and select ‘Off’ 2 times.
Then right-click and select Enter. All layers will be off except one.
The Short-cut key is ‘LAYUNISO’. Unisolate restores all layers that were hidden by the Isolate command.
Short-cut key is ‘LAYERP’. It undoes last changes of only layer command.
22. Change to the current layer
The Short-cut key is ‘LAYCUR’.
By using change to the current layer, we can transfer the object from another layer to the current layer. For example, some walls are located in the window layer by mistake, and then we can transfer it to the current wall layer by suing Change to the current layer quickly.
First, select the ‘Change to current layer’.
Then select object that you want to change layer.
Right-click and select Enter.
23. Copy object to the New layer
The Short-cut key is ‘COPYTOLAYER’. This creates a copy of the object in another layer the same as a copy command.
Select ‘Copy object to New layer’. And then select the object which you want to copy.
Select that layer object in which you want to copy object. Right-click.
Select base point of the object and it will make a copy in another layer.
The Short-cut key is ‘LAYWALK’. Yes, by using layer walk, we can walk in layer according to its name.
When we select any one layer in the layer walk, all the layers except that selected layer will be turned off, and only selected layer objects will appear on the screen. So, we can review objects in each layer.
If you have selected the Wall layer, then it will appear only objects included in the wall layer.
The Short-cut key is ‘LAYMRG’. We can directly merge the layer in the current layer by selecting the layer.
Click on the ‘Merge’ and select an object to merge the selected layer in the current layer.
Right-click and select Enter key.
Another method is, Select layer to merge in the ‘Layer Properties’.
Right-click and select ‘Merge selected layer(s) to’. And select the layer in which you want to merge.
Layers will be merged and old layer will be deleted.
The Short-cut key is ‘LAYDEL’. We can delete the layer by direct selecting any object of that layer. But we can’t delete the current layer.
Select ‘Delete’ and select the object. Right-click and select Enter.
Layer will be deleted.
Use layer properly by practicing and knowing the functions properly. If you are not using layer command, you should start from now. It will give benefit to all including you!!
It’s done here. I hope I have added some value in your knowledge.
