Effective Techniques to Reduce DWG File Size in AutoCAD for Optimized Performance

Large AutoCAD files can take a long time to open, modify, reference, save, and email. You might even see the dreaded “Fatal Error” message when you try to Open, zoom or pan in your drawing.

If your AutoCAD file is too big, it’s probably because there are unnecessary objects or layers in it. Or, your objects might be needlessly complex (for example, if you’re using too many polygons to represent a circle).

In this article, we’ll discuss about the most common reasons why a CAD file is so heavy and methods to reduce the size of your AutoCAD drawings. These methods have been tested on DWG files ranging from 1 MB to 100+ MB.

Your AutoCAD drawings are too big, and you don’t know how to make them smaller. The files take too much time to open, save or work in the file. Additionally, large files may take longer to transfer over internet connections due to their increased size in bytes.

AutoCAD issues related to file size

Scale List Issue

The issue occurs when importing AutoCAD files created using AutoCAD 2008, which introduced annotation scaling.

The bug from AutoCAD 2008 copies all annotation scales from x-referenced drawings into the host drawings, even if they already existed. This creates a massive number of unrequired scales in your drawing. Furthermore, modern releases of AutoCAD have an automatic detection system for this problem, prompting you to reset the scale list if you open a problem file.

DGN Lineweight

The DGN Lineweight can cause file sizes to increase because it contains proxy data. These proxies are used to store information about the lineweights in a drawing, and they do not affect the appearance of the drawing.

When these proxies are present in a DWG file, they increase their size by up to 50%, as described by Kean Walmsley in his Through the Interface post. This can lead to larger-than-normal file sizes and slow down rendering times when working with drawings containing these proxies.


The size of a DWG file can be affected by many factors, such as the complexity of the geometry and the number of layers used. Additionally, AutoCAD may not optimize the file size correctly when saving it or using certain features such as block references and external references.

The large DWG file size can lead to longer save times, slower performance when opening or editing files, and increased disk space usage. It can also make it difficult for users working on shared network drives or computers with limited resources to access their drawings quickly and effectively.

What factors affect the size of a DWG file?

Below are some known reasons why your AutoCAD file size is increased.

1. Drawing complexity

Drawing complexity can affect the size of a DWG file by increasing its size. This is because complex drawings often contain more objects, layers, external references, and line weights, which increases the file size.

As a result, large DWG files can take longer to open and load than smaller ones. Additionally, zooming in on an image with a large file size may cause it to become blurry temporarily until it loads fully again.

2. File Type

The size of a DWG file is affected by the file type, as some of the file types will be larger than others. For example, DWG files containing 2D and 3D image data will be larger than those containing only 2D objects. Additionally, certain file types, such as DGN, require additional software to open them compared to other formats like DWG or DXF.

However, some factors can affect the size of a DWG file regardless of its type. For example, if you have large amounts of complex geometry or text in your drawing, then it will take up more space on your computer’s hard drive and therefore increase the overall file size. Similarly, suppose you have many layers with lots of items on each layer. This can also increase the overall size due to the extra information being stored in each layer individually.

3. Number of Layers

A DWG is a file format used to store vector graphics, such as lines, curves, and shapes. The Layers then classify these objects feature in AutoCAD, which is known as Levels in MicroStation.

A DWG file can contain multiple layers, which organize different types of content in separate layers. Each layer can contain unique attributes such as color or transparency settings. There may be hundreds of layers in a single DWG file depending on the complexity of the design it contains. The layers are numbered sequentially and can be identified by their names in the Layer List window that opens when you open a DWG file in AutoCAD® software.

4. Number of Objects

The number of objects in a drawing file affects the size of the file. More objects mean more hatches, blocks, lines, shapes, images, and other elements that must be stored in the file. This increases its overall size, resulting in a larger DWG file.

As a result, larger DWG files take longer to open and save since more processing power is required to process all of the data contained within them.

5. Type of Hatch

The size of a DWG file based on the type of hatch will usually increase as the complexity and density of the hatch increases. For example, line-based hatches add more vector information for each line, whereas sand hatches use vector information for each dot.

However, solid-looking hatches that are extremely dense may need to be switched to an actual solid pattern to reduce file size.

6. Number of Drawings Included

The number of drawings that can be included in a DWG file depends on the size of each individual drawing and how it is organized. For example, if the drawings are small and grouped together into one folder, then more than one drawing could be included in the same DWG file. Alternatively, if each drawing is large and separated into its own folder or layer, then only one drawing would be able to fit in the DWG file.

7. Image Resolution

Image quality affects the size of a DWG file because higher-quality images require more disk space than lower-quality images.

As a result, larger DWG files will be created if high-quality images are used compared to smaller ones when lower-quality images are used.

The size of a DWG file is directly affected by the resolution of an image. The higher the resolution, the larger the file will be; conversely, lower resolutions result in smaller files.

8. Object Transparency

Using transparency features in complex drawings may result in slower processing drawings.


You could spend hours googling ways to reduce the size of your AutoCAD file, or you can follow these eleven simple methods to ease your workflow.

Back up before you mess up!

Follow these three steps before trying to clean up or reduce the size of your files.

1. Save a copy of your production DWG files before you reduce their size in AutoCAD.

How to make the dwg file smaller

Follow these five steps to reduce the size of your AutoCAD drawing quickly and easily.

Reducing the file size of your drawings is essential for two reasons: first, it can save you time when opening and working on files; second, reducing the file size can improve performance when transferring files to other software.

By following these five simple steps, you’ll be able to reduce the size of your drawings without losing any information or quality.

Step 1: Is this a colorized rendering plan?

This is a colorized rendering plan, which may be contributing to its large file size. To reduce this size, use the recommendations in the articles listed above.

This is not a colorized rendering plan as indicated by the black and white image. If it were, then it would likely have a larger file size than usual due to the addition of color information.

Step 2: Convert to .dwg

1. Click File > Save As.

2. Browse to find the location or folder where you want to save the drawing and then click OK.

3. In the Save as type list, select AutoCAD Drawing (* .dwg) as the file type and then click Save.

4. If your Visio file has more than one drawing page, you must save each page separately by selecting AutoCAD Interchange (* .dxf) as the file type instead of AutoCAD Drawing (* .dwg).

Step 3: Reduce color bit depth

1. Open AutoCAD and select the DWG file you wish to reduce in size.

2. Go to the “File” menu, then select “Options” and choose the “Color Settings” option from the list of options that appears.

3. In the Color Settings dialog box, adjust the bit depth slider until it reaches a level that is suitable for your needs (usually 8 or 16 bits). This will reduce the number of colors used in your file and subsequently reduce its file size significantly.

Step 4: Remove render settings

1. Open the DWG file in AutoCAD and select ‘FILTER’ from the ‘LAYERS’ menu.

2. Enter ‘RSET’ into the dialog box that pops up, then click on ‘OK’ to remove render settings from your DWG file.

3. Press ENTER on the FILTER command again to confirm that you want to remove all render settings from this file and exit out of FILTER dialog box when done with cleaning up unwanted layers/filters/settings etc..

Step 5: Convert to solid modeling

1. Open or import the DWG file that you want to convert into solid modeling.

2. Right-click on the drawing, point to CAD Drawing Object and click Convert.

3. In the Convert CAD Object dialog box, select the check boxes for the AutoCAD layers that contain objects you want to convert into Visio shapes and uncheck any layers that should not be converted (such as background or reference layers).

4. Under Advanced Options, select any additional settings such as deleting converted layers after conversion is complete or converting hatch lines into shapes instead of lines (if applicable).

5 . Click OK once all desired settings have been selected then wait while AutoCAD converts them into Visio shapes .

How to Optimize Your AutoCAD Drawing for Maximum Performance

1. Back up your AutoCAD drawing before attempting any optimizations.

2. Remove unused blocks, layers and Xrefs from the drawing to reduce its size and complexity.

3. Use Polylines instead of complex shapes whenever possible, as they are more efficient in terms of performance and file size.

4. Use Hatch patterns instead of Bitmap images whenever possible for better efficiency with large drawings or those that require frequent updates (Hatch patterns can be scaled without losing quality).

5. Minimize the number of linetypes used in your drawing by only using those that are necessary for readability purposes (Linetypes can slow down AutoCAD when there are too many present).

Autocad file size reducer lisp

1. Launch AutoCAD and open the file you wish to reduce in size.

2. Click on the “File” menu and select “Send to” then click on “PDF Writer” or “Output”.

3. In the PDF Writer dialog box, adjust the settings as desired (such as page layout, quality, etc.). You can also use a pre-existing PDF template for a quick start if desired..

4 . Once you are satisfied with your settings, click “OK” to begin reducing your file size by converting it into a PDF format document .

5 . After conversion is complete , check the new file size and compare it with the original one; if necessary , repeat steps 3 – 4 until you are satisfied with results..

Other optimization

Tips from Mateen Gohar:

Mateen Gohar has the following tips for optimizing huge CAD files in AutoCAD, Microstation, or other CAD software:

– Optimize images by using a tool such as TinyPNG or Photoshop.

– Reduce the number of layer filters you use to minimize conflicts and optimize performance.

Tips from Sultan:

– Use less number of blocks, complex hatches, external references, or images in the drawings.

– Divide your complex drawings into separate drawings and use external references to control the level of detail required.

This will also help work faster and more efficiently in CAD files, instead of opening a CAD file with the floor plan, lighting plan, and plumbing details all in one, with a file size of 8mbs. You can split the file into files like Floor Plan, Plumbing Layout Plan, and Lighting Plan.

Tips from Rizwan Veero:

Tips for optimizing CAD files include:

– Use the least possible number of layer filters.

– Avoid using complex hatches in the drawings.

– Use the Purge command frequently to delete excess information from the drawing.


What is the purpose of reducing the size of a DWG file in AutoCAD?

The purpose of reducing the size of a DWG file in AutoCAD is to make it easier to open, save, and email the file. A smaller file size means less data for AutoCAD to process, which can speed up the program’s performance.

Reducing the size of a DWG file in AutoCAD is the process of reducing its size to make it less heavy and easier to manage.

The main reason why you may want to reduce the file size of a DWG file is so that it does not slow down your system or crash it. It can also be helpful if you need to send the file as an attachment or upload it somewhere, as smaller files are easier to transfer. To reduce the size of your DWG file, you can use tools such as AutoCAD’s “Reduce File Size” feature which compresses all images within that document into one single image with lower resolution settings.

What are the benefits of reducing the size of a DWG file in AutoCAD?


The benefits of reducing the size of a DWG file in AutoCAD are that it can help improve performance when opening, editing, and saving drawings; make it easier to share drawings with others; and reduce the amount of disk space required to store drawings.

How can the “Purge” command be used to reduce the size of a DWG file in AutoCAD?


The “Purge” command can be used to remove unused items from a drawing, which will help reduce the file size. To use the command, type “purge” into the command line and then select the type of object you want to remove.

1. Open the DWG file you wish to reduce in size.

2. Type “pu” or “purge” and check the boxes for purging everything, including nested items and orphaned data. Don’t check “Confirm each item to be purged” or you’ll likely be there a while.

3. Save the drawing afterwards and check file size for any improvement in size reduction..

How does the “Audit” command help to reduce the size of a DWG file in AutoCAD?


The “Audit” command in AutoCAD can help to reduce the size of a DWG file by identifying and fixing errors within the file. This can help to improve the performance of the file and make it more manageable.

The “Audit” command in AutoCAD helps to reduce the size of a DWG file by identifying and removing any errors or unnecessary objects from the drawing. It scans through all layers and blocks, checking for errors such as missing linetypes or broken references. Once it has completed its scan, it displays a list of any issues that need to be fixed before continuing with other processes. The “Audit” command can be accessed by typing AUDIT at the command prompt and pressing enter, or from AutoCAD’s menu (the big red A) > Drawing Utilities > Audit.

What is the “WBlock” command and how does it reduce the size of a DWG file in AutoCAD?


The Wblock command in AutoCAD creates a drawing block from selected objects or a specified area and writes it to the current directory. The block is then inserted into the drawing as a single object. This command can be used to reduce the size of a DWG file by creating a smaller drawing block that only includes the objects you need.

The WBLOCK command is a built-in command in AutoCAD that writes (saves) the objects in a drawing as a new drawing. It can be used to save specific objects or the entire drawing and quickly reduce file sizes.

To use this command, you first need to type WBLOCK on the command line or choose Insert> Block Definition panel> click the Create Block drop-down arrow and choose Write Block. Then, you can specify which objects should be written to the new file by choosing Entire Drawing at the top of the dialog box, specifying a base point if desired, selecting whether to retain or convert objects from current drawing into blocks ,and then choosing where to save it with an ellipsis button . You also have options for units and light years/parsecs . After clicking OK ,the selected objects will be written into a new DWG file with reduced size compared to original one .

How can the “Format” tab be used to reduce the size of a DWG file in AutoCAD?


The Format tab can be found in the Page Setup dialog box. Under the Layout Elements heading, there is an option to include or exclude a variety of elements from the exported file. Excluding certain elements can help to reduce the file size.

How can exporting to a different file format help to reduce the size of a DWG file in AutoCAD?


When you export to a different file format, you are able to select which objects and layers are exported. This can help to reduce the size of the final file by excluding unneeded data. Additionally, exporting to a format that uses lossless compression can also help to reduce file size.

Exporting to a different file format such as DWG can help to reduce the size of a DWG file in AutoCAD.

By converting the file from DXF to DWG format, which is made up of 1s and 0s rather than ASCII text, the file will be much more compact and therefore smaller than its original size. Additionally, removing raster data from your CAD file can also help reduce its size.

What are the most common causes of a large DWG file in AutoCAD?

There are a few things that can contribute to a large DWG file size in AutoCAD, including the number of objects and layers in the drawing, the level of detail in objects, and the amount of text or raster images in the drawing.

The most common causes of a large DWG file in AutoCAD include importing a drawing file from a third-party with different linetypes, importing a non-AutoCAD drawing with different linetypes, using excessive RegApps in the file, and creating the file using other applications instead of AutoCAD.

When DWG files become bloated and increase in size, it is usually due to corruption. This can make them difficult to work with as they will load slowly and hang often.

The size of a DWG file is affected by a variety of factors, including:

– The complexity and number of objects in the file

– The level of precision used when creating or editing objects

– The number and type of layers used in the file

– The settings used when exporting or printing the file

Can we compress DWG file?


Yes, you can compress DWG files. This is done by reducing the file size without compromising quality or losing data. When compressing a DWG file, you will be asked to select a compression method. The two methods are:

– Run Length Encoding

– Deflate

Yes, it is possible to compress DWG files. By using standard compression methods such as ZIP, you can reduce the file size of your CAD drawings. Additionally, switching from DXF to DWG format will also reduce the size of your file since DWGs are made up of 1s and 0s instead of ASCII text like DXFs.

No, it is not possible to compress DWG files without losing data. You should only use standard compression methods if you need to send a file by email or transfer it over the internet.

Why is my DWG file so big?


There are a few reasons why your DWG file might be too big. One possibility is that you have inserted a lot of raster images into the drawing. Another reason could be that you have made a lot of changes to the drawing, and the file hasn’t been purged or cleaned up.

The size of a DWG file can end up being larger than it should due to several reasons, such as importing a drawing file from a third-party whose linetypes are different from those of AutoCAD, or if the source file is damaged.

As a result, affected objects in the drawing file become unidentifiable blocks and damage the original features of the file. Additionally, if you create a DWG file using other applications other than AutoCAD there is a possibility it will become corrupted.

How can I troubleshoot DWG file size problems in AutoCAD?


There are several ways to troubleshoot DWG file size problems in AutoCAD. One way is to use the ‘PURGE’ command, which will remove unused items from the drawing. Another way is to use the ‘AUDIT’ command, which will find and fix errors in the drawing. Finally, using a smaller scale when plotting can also help reduce file size

1. Check for any RegApps that may be excessively used in your DWG file. Remove them if necessary.

2. Use AutoCAD’s “PURGE” command to remove any unused items in the file and reduce its size considerably.

3. Use specialized software such as Autodesk Bundle Assistant or AutoCAD Repair Wizard to recover corrupted DWG files and retrieve lost items if necessary.

What is AutoCAD?

AutoCAD is a computer-aided design (CAD) software used for creating and editing 2D and 3D designs.

AutoCAD allows users to create drawings, models and documents of high quality. It provides a wide range of tools that allow users to draw complex shapes easily. AutoCAD also has advanced capabilities such as 3D modelling which makes it suitable for complex architectural designs or engineering projects. Additionally, it comes with a library of pre-made objects that can be easily inserted into drawings for added realism and clarity in presentations or final products.

What is the Purge Command in AutoCAD?


The purge command is used to remove unused items from the drawing. These items can include block definitions, layers, linetypes, styles, dimensions, etc. The command will also help to improve the performance of the drawing.

The Purge Command in AutoCAD is a command that allows you to remove unused objects such as block definitions, styles, materials and layers from your drawing’s database.

When you run the PURGE command at the command line, AutoCAD will open a dialog box where you can select which items you want to purge from your file’s database. You can choose to purge block definitions, styles, materials and layers or check the “Purge nested objects” box if needed. Additionally, AutoCAD 2010 includes an option to clear out empty text lines and zero length lines while AutoCAD 2012 allows you to purge empty groups as well.

What is the WBlock Command in AutoCAD?


The WBlock command in AutoCAD is a great way to create a new drawing file from an existing one. The WBlock command allows you to select objects from the current drawing and then create a new drawing file that contains only those objects. This is a great way to create smaller, more manageable files from larger ones.

The WBlock command in AutoCAD is a command used to save selected objects from one file to another clean file.

When using the WBlock command, you first select the objects you want to save and then type WBLOCK followed by enter. This will create a new clean file with only the selected objects in it. The original file will remain unchanged and any excess geometry left behind after using this command may become corrupted.

What is File Bloat and how does it affect DWG file size?


File bloat is the result of a file containing excessive data that is not required for the intended purpose of the file. This can happen when files are created with unnecessary layers, objects, or other data. File bloat can cause problems when files are transferred or emailed because the larger file size can take longer to upload or download. Additionally, files with excessive data can be more difficult

File Bloat is the increase in size of a DWG file due to the presence of unnecessary data.

File Bloat occurs when a DWG file contains redundant or outdated objects such as linetypes, layers, blocks, and regapps that are no longer needed. This can happen when you import drawings from other applications or when you use linetypes that are different from those used by AutoCAD. Furthermore, if the source file is damaged or corrupted then it can lead to increased bloating of the DWG file which will result in slower loading times and difficulty working with it.

How can I reduce the size of a PDF file in AutoCAD?

2. Select “Save As” from the File menu, then select “PDF (Portable Document Format)” as the file type and click “Save”.

3. Go to SmallPDF.com and enter your PDF file into their online converter tool (it’s free).

4. Set your desired output quality level then click “Convert” to start converting your file into a smaller version with reduced size and quality settings that are suitable for viewing onscreen or printing at low resolutions (such as black & white or grayscale printing).

5 . Once completed, download the newly converted PDF file from SmallPDF .com’s website and save it in a location of your choosing for future use

What is the Hatch Pattern in AutoCAD?


The Hatch Pattern is a fill pattern that can be applied to an object or area. It is often used to fill in areas with solid colors, but can also be used to create gradient fills or other more complex fills. The Hatch Pattern can be applied to objects in AutoCAD by using the HATCH command.

The Hatch Pattern in AutoCAD is a type of fill used to fill areas with a pattern or texture. It can be used to represent various types of materials, such as metal, wood, and stone.

To create a Hatch Pattern in AutoCAD, you first need to define the boundary of the area that you want to fill with the pattern. This can be done using lines or polylines. Once you have defined the boundary, select “Hatch” from the Draw menu and then select one of the available patterns from the drop-down menu. You can then adjust settings such as scale and spacing for better results.

What is the Filter Command in AutoCAD?


The Filter command in AutoCAD is used to select objects based on certain criteria, such as color or layer. This can be helpful when trying to isolate a specific object or group of objects in a drawing.

The Filter Command in AutoCAD is a command that pops up a dialog box that allows users to quickly delete unused layer filters from their DWG files.

To use this command, type “FILTERS” at the AutoCAD command line and then select the layers you want to remove from the file. The FILTERS command works like an Uber Quick Select tool, where users can quickly select multiple layers at once and remove them from their drawing. It also allows users to view which layers have been removed and which remain untouched so they can ensure they are removing only unnecessary filters from their files. Additionally, this command has an option to save changes before running it again so users can ensure they have optimized their file before committing any changes permanently.
