Layers are the basic method of organizing the position of objects in 2D and 3D graphics. Many architects implement AutoCAD layers to control the layer properties of their drawings on a page.

These layer properties include line weight, line type, color, and description. They are generally used to determine the appearance of objects on layers in AutoCAD.

Different forms of layers have their unique names. Interestingly, you may choose to group them alphabetically or numerically, depending on the requirements of your project.

In this article, we will discuss the definition, properties, creation, and management techniques of layers in AutoCAD.

What Are Layers in AutoCAD?

In AutoCAD software, layers are drawing planes that help you to easily control the properties and visibilities of objects. Examples of these objects include:

• Lines
• Images
• Blocks
• Tables
• Spreadsheets

You can use layers to manage or control the visibility of objects by activating the on/off command.

Similarly, you can also control the visibility of objects by using the freeze/thaw command.

The only difference between the freeze and turn off command is that the freeze unloads the layer from its memory. The table below contains other possible basic layer commands in AutoCAD plot settings.

Keep in mind that one drawing can have many layers, depending on the dimension, style, and complexity of the drawing. You can use each layer to draw a specific object type. For example, you can complete the drafting process by using:

• Wall layer to draw walls
• Door layer to draw doors
• Window layer to draw windows
• Column layer to draw columns.

Layer Properties

Layer Properties are responsible for controlling the visibility of different objects within a drawing. Here is a list of the main layer properties in AutoCAD:

1. Name
2. Color
3. Linetype
4. Lineweight
5. Transparency

Each layer in AutoCAD has a specific name that makes it unique in the layer tab. For example, in the diagram below, the default layer is called ‘reference’, while the current layer is called ‘walls’.

These names make it quick and easy for architects and engineers to find a certain layer by using the layer properties button.

To assist in visual distinction, all layers are created with different colors in the layer manager palette. For example in the above diagram, the reference layer is assigned a red color, while the current layer is given a blue color.

Layer color can also be useful for visual interpretation. This may look surprising, but in places like California, Texas, New York, Florida, and Illinois, people recognize blue color as an essential part of plumbing.

Therefore, AEC professionals use it as the appropriate color for plumbing fixtures, such as water pipes, sinks, and drainage pipes. Another important layer property is the linetype, which basically refers to the style of lines or geometry of the layer.

Some common examples of linetype include solid lines, dotted lines, and dashed lines. They play a crucial role in layer management and object selection, ensuring precise representation of graphics.

Furthermore, each line on a layer has a thickness that ranges from 0.10-1.50 mm, depending on the line weight of the specific layer. This means that the lines can only be plotted with a minimum thickness of 0.1 mm and a maximum thickness of 1.5 mm.

Creating & Managing Layers

You can create and manage layers in the layer manager palette. To carry out this process, you need to first open the home tab layer panel > Click on the layer properties button and select layer properties manager. Now, activate the layer manager by using “LA” as a shortcut.

In the layer manager, you can create new layers with the shortcut key, Alt + N. By default, the new layer will be named Layer 1. However, you can rename the layer with a name that best fits your project.

The next step is to select a suitable color, linetype, and lineweight for the new layers. To do this, simply navigate your system cursor to the column containing color, then select a unique color for each layer.

Now, move the cursor to the next two columns containing linetype and lineweight, then select the appropriate parameters that fit the rows in each column.

To effectively manage the newly created layers, you can use the basic layer commands, which we earlier discussed in the previous section of this article.

In addition, It is important to take note that the shortcut key to delete a layer is AIt + D, and the shortcut key to set a layer as the current layer is Alt + C. Therefore, the shortcut to most layers is simply Alt + the first letter of the layer’s name.

Advanced Layer Techniques

Elements are separated into different layers through the help of the advanced layer techniques in AutoCAD. These techniques include:

• Layer states: The primary role of the layer state is to assist you in managing many layer configurations at the same time. For example, when drawing a large building plan, layer states help you to easily hide the door layer while working on the wall layer.
• Layer filters: To improve the visibility of relevant layers in AutoCAD, try using layer filters to first filter the layer properties before using the freeze/thaw command.
• Layer transparency: This allows the lines and columns on a top layer to appear white or transparent, making the layer beneath more visible in 2D drawings.

One of the most significant hurdles for home design professionals in the construction industry is figuring out which software is the right choice for their projects. For compatibility, there are Microsoft and Mac software programs to choose from. These can range from basic, open-source design tools to advanced programs with add-ons and plugins. Some construction software can even be complemented with AI, getting new functionality and allowing for more streamlined processes. Then there is the cost to consider, which can be free to tens of thousands of dollars. 

Another issue is that many of these computer-aided design software tools are designed to simulate different things. They work in different phases of the construction process, meaning you need to know how each phase evolves when making the best choice for your workflow. Either way, once you understand the general CAD software principles, it is easier to understand and pick up new CAD software.

There are many different types of construction design software, and they are generally categorized by which profession they are made for.

Top Software

Software for a civil engineer won’t work the same way when the chief architect uses it. You also need to understand building information modeling (BIM), which is the general category that most construction CAD software falls into. However, your choice for architectural design, interior design, and building design software in the industry will always start with your specific situation.

AutoCAD

Software for reliable 2D and 3D drafting

While not specifically built for construction, AutoCAD is the grandfather of professional CAD software. Over the years, it has set the trends in this industry and paved the way for other user-friendly programs such as SketchUp. It has toolkits for many industries, but its architecture toolset is notably quite advanced. With this tool, you can design 2D and 3D models. You can also do things like compare drawings and count objects. AutoCAD also makes it easy to do 2D floor plans, 3D floor plans, elevations, and 3D designs. It gives you all the tools you need to create a useful 3D model that represents what you are trying to create.

Rhino

An affordable entry-level CAD system 

Rhino is used by architects and engineers to design, model, present, and analyze various projects. It has multiple editing modes, meaning you can utilize NURBS or traditional geometric tools to create blueprints. It also meshes with a whole host of CAM, engineering, and rendering suites. The best thing about this program is how affordable it is compared to its competition. It even has integration with various digital fabrication tools. For example, it can be utilized with 3D printing equipment.

Autodesk Navisworks Manage

Wipeouts are a simple but powerful tool in the AutoCAD tool box. By learning how to use them effectively, you can significantly increase the clarity and readability of your drawings, resulting in a more professional look. In this guide, we will explain what Wipeouts are, when and how to use them, and some tips and tricks for keeping things clean when the time comes to plot your drawings.

What is a Wipeout?

Wipeouts are an AutoCAD feature that allows you to hide or cover objects in a drawing, making your sheets cleaner and easier to read. Think of them like digital sticky notes you can add and remove anytime.

The Wipeout command creates a mask over your selected area, allowing you to cover distracting information without deleting it from your model. Wipeouts can be placed as squares, rectangles, or custom polygons to best suit your drawing needs.

When to Use Wipeouts in AutoCAD

Various situations call for Wipeouts. Here are three of their most common uses.

• You Want to Make Your Schedules and Tables More Legible: Wipeouts can be used to obscure the complex linework behind schedules and tables, ensuring that the text is readable and stands out against busy backgrounds.
• You Want to Hide Objects That You Don’t Want to Plot: Wipeouts are perfect for masking parts of your drawing that are unnecessary in your final plot, such as preliminary notes or reference lines.
• Creating Blocks: You can use Wipeouts to create blocks that won’t interfere with details behind in the draw order. For example, Wipeouts can be used when creating furniture blocks, allowing you to move them around without disturbing flooring hatch patterns.

Getting Started with Wipeouts

Now that we’ve established what Wipeouts are and when to use them, let’s get into how to create your first Wipeout.

Accessing the Wipeout Command

There are two ways to activate the Wipeout command in AutoCAD. The easiest way is to simply type “WIPEOUT‘ into the command line and hit “ENTER” when in model space. You can also access the Wipeout command from the Ribbon. Find and select the “Annotate” tab. On the right side of the Ribbon, you will find the Wipeout tool within the Markup Panel.

Creating Your First Wipeout

After you activate the Wipeout tool, AutoCAD will ask you to specify your boundary points. By default, AutoCAD including specialized toolsets will start to create a polygonal shape. Now, simply draw a polyline surrounding the objects you want to mask with a Wipeout, and then hit ENTER to terminate the command. You will see the covered objects disappear, and a frame in the shape of your polyline will take its place. Congrats, you’ve just created your first Wipeout!

Advanced Techniques

Creating basic Wipeouts is a simple process. However, there are times when you will need to tailor your Wipeout further to fit the needs of your project. In this case, here are a few advanced techniques to remember.

Creating Wipeouts Using Existing Polygons and Polylines

Though AutoCAD allows you to create new Wipeouts, you can also create them using existing shapes and polylines. This may be useful when working with intricate shapes or pre-existing room boundaries.

To create a Wipeout from an existing shape, follow these steps:

1. Ensure you are working with a closed polyline. If you are unsure how to do this, you can refer to this guide on AutoDesk’s Website.
2. After you have made sure that your polyline is closed, initiate the Wipeout command.
3. Now, instead of starting to draw, navigate down to the command line. Here you will see a message saying, “Specify first point or [Frames/Polyline].”. Click on Polyline.
4. At this point, you will be asked to “select a closed polyline.” Once you’ve picked your existing polyline, you will be presented with one final option: Erase polyline. Yes or No.
5. If you click “Yes”, your shape will be deleted and replaced with the Wipeout boundary. If you select “No”, your shape will remain, but the Wipeout will be laid over it.

Editing and Managing Wipeouts

There are a few different methods you can use to make adjustments to your Wipeout. To change the layer or line type, select your Wipeout, type PROPERTIES into the command line, and hit ENTER. If you want to change the shape of your Wipeout, select it, right-click, and choose edit from the dropdown menu. Now, you will be able to move, resize, and adjust the shape of your Wipeout using the grips.

Tips and Best Practices

Wipeouts can work wonders for keeping your plans neat and tidy. However, if they are created incorrectly, they can look a little sloppy when you see them on paper. Here are a few tips and best practices for keeping your drawings clean with Wipeouts.

• Turn Off Wipeout Frames Before Printing: Wipeout frames are helpful during the editing process as they show the boundaries of the Wipeout areas. However, if left visible, these frames can clutter the final print. Before printing or sharing your drawings, make sure that all your Wipeout frames are turned off. This can be done by setting the system variable FRAME to 0, which hides the frames while keeping the Wipeout functionality intact.
• Utilize the Draw Order Function: If not managed correctly, wipeouts can sometimes obscure essential parts of your drawing. To prevent this, use the draw order function to send Wipeouts to the back of the drawing order. This guarantees that all other drawing elements, such as text and lines, remain visible and are not masked unintentionally by the Wipeout.
• Check Wipeout Visibility in Different Viewports: If you’re working with multiple viewports in model space or paper space, Wipeouts might behave differently in each viewport. Check to see if Wipeouts are correctly configured and visible in all relevant viewports to ensure consistent visibility across the different views of your project.

Explore Other Useful AutoDesk Tools

Once you discover Wipeouts, they can be an absolute game-changer for your AutoCAD workflow. However, they are just one tool in an extensive library of commands that can boost your productivity in your specific discipline.
