I have a very large file that I need to reduce in size. Is has just 3 poly lines in it and the file size is 10MB. As soon as I copy anything from this file to another file, the other file also increases in size. I tried Purge, Audit, WBlock, Scale list Utility, Purge Regapps, Recover but all in vain. Can someone please help. Thanks in advance. Reducing The PDF File Size. Properly using True Type Fonts in AutoCAD when creating PDF flies with CADzation software will result in PDF files that are a much as 12 times smaller in file size. The other added benefits are PDF's that will view and print faster due to the reduced file size. The text in the PDF's will also print sharper. Dec 10, 2013  When working with AutoCAD, sometimes you can see that your files get unusually large. It may slow your system down and it might crash the system. You might want to try to reduce the file size. Other reason why you want to reduce the file size is because you need to send it.

Issue:

There are many reasons for the file size to be large, blocks, dictionaries etc. Run the purge command 3-times in a row, see what that does. (multiple times needed to get to nested blocks) There are also many threads here and other sites addressing this issue. Please conduct a thorough search. AUDIT – Be used to check for drawing. AUDIT not reduce file size. But it is encouraged to check the file before proceeding with other processes. It will maintain the integrity of the drawing and fix the errors which may prevent to remove unnecessary objects. Command: AUDIT or File Drawing Utilities Audit. Open the file with AutoCAD LT. DXFOUT the full file. In a new file DXFIN the file created in previous step. After importing the DXF, generate a new DXF file (DXFOUT). In a new file DXFIN the file created in previous step. Save the file. WBLOCK to remove line types: Open the file with AutoCAD LT. Enter the WBLOCK command. Reduce the size of an existing file without much modifications and redoing. Here are some methods. Set the incremental save percentage. This is a tricky (because it a trade off between saving speed and file size) and lesser known fact about Autocad. It is set in the options under open and save. The default is 50. It is s system setting.

Drawing files in AutoCAD end up being much larger than they should, often with no obvious data in them. Other symptoms include:

• Failure to copy and paste elements.
• Hanging for a long time when selecting text with the properties palette open.
• Drawing file takes a long time to open.

Causes:

• This happens when data is imported from a DGN file and the original linetypes were not mapped or were incorrectly mapped to AutoCAD linetypes. This produces a huge object database in the drawing that cannot be purged with the standard tools. Furthermore, if you copy and paste an entity from an affected drawing into another drawing, the entire database is also copied and the problem is spread to the other file.
• The DWG was created in different application to AutoCAD

Solution:

Open affected drawings in AutoCAD 2015 (or a later version) and use the PURGE command. Be sure to enable the checkbox labeled 'Automatically purge orphaned data.' This new purge option was added in AutoCAD 2015 as a result of the hotfix being rolled into the program, with the enhancement.
For AutoCAD 2012, 2013, and 2014, there is the DGN Hotfix.
AutoCAD DGN Hotfix for AutoCAD 2013/2014
AutoCAD DGN Hotfix for AutoCAD 2012
The hotfix includes two files:

• DgnLsPurge.dll. Once loaded, it allows you to purge DGN objects using the DGNPURGE command.
• AcDgnLS.dbx. This keeps the DGN objects from propagating to new files when copying, pasting, or inserting from other files.

Refer to the associated readme files for instructions. Usually, the hotfix files will need to be unblocked in order to work and there is a screen shot about this in the readme.

How To Compress Autocad File

To use the new command, enter DGNPURGE on the command line in AutoCAD to remove unwanted DGN elements. It gives no feedback until done, so on very big files you will simply need to wait until it is finished, which could take several minutes. After it is done, use PURGE > All on the drawing.

Autocad File Size Reduce Commands

The large file size problem is partially solved with Service Pack 1 for both AutoCAD 2014 and AutoCAD LT 2014, stopping the propagation of unwanted line types between files. The service pack does not contain the DGNPURGE command, which is needed to clean already affected files.
Using DGNPURGE on multiple files at once
There is a third-party plug-in called Drawing Purge that can be added to AutoCAD which will let you purge multiple drawings all at one time.
AutoCAD LT and the DGN Hotfix
AutoCAD LT does not have the NETLOAD command which is needed to load the hotfix DLL file, which means the DGNPURGE command is not usable within AutoCAD LT. However, beginning with AutoCAD LT 2015, the enhanced PURGE functionality is included, so it is recommended to use version 2015 (or newer) to purge affected files.
As an alternative to the hotfix, converting a DWG file to DXF and then back again, or to DGN and back, or using WBLOCK to write a new file has the potential to remove unwanted DGN elements.
DXFOUT to remove line types:

1. Open the file with AutoCAD LT.
2. DXFOUT the full file.
3. In a new file DXFIN the file created in previous step.
4. After importing the DXF, generate a new DXF file (DXFOUT).
5. In a new file DXFIN the file created in previous step.
6. Purge all.
7. Save the file.

WBLOCK to remove line types:

1. Open the file with AutoCAD LT.
2. Enter the WBLOCK command.
3. Select the 'Entire drawing' option.
4. Click the location button at the bottom-right to name the file and pick a location to save to.
5. Click OK.

Visual basic 2012 download free full version. DGNEXPORT to remove line types:

1. Open the affected drawing file using AutoCAD LT.
2. Enter DGNEXPORT at the command line.
3. Select V8 DGN under 'Files of type' and click Save.
4. When the Export DGN Settings message box is displayed, verify that the correct seed file and units are selected.
5. Click OK.
6. After the DGN export is complete, open a new template and enter DGNIMPORT at the command line.
7. Select the newly created DGN file and click Open.
8. Verify that the Conversion unit is correct.
9. Click on Mapping setups and select new and make sure Mapping type is Import.
10. On the new Mapping setup, click on Modify.
11. Go to the Linetype tab, change all rows to ByLayer (right-click on the first row which has been set to ByLayer and the select Copy, then select all the rows and right-click > paste).
12. Click OK.

COPY and PASTE
If you have installed Service Pack 1 for AutoCAD and AutoCAD LT 2014, try the following procedure if previous methods fail:

1. Open the DWG file.
2. With the LAYER command, assure that all layers are on, thawed, and unlocked.
3. Copy all objects in the drawing to the clipboard (CTRL+A then CTRL+C).
4. Open a new file and paste all copied objects (CTRL+V).
5. Save the file.

If you see increase in file size during an export to DGN, please make sure to uninstall all the older version of DWG True view and install the one corresponding to your AutoCAD release. You can download it from the following location,

VIEWBASE - DRAWING VIEWS
Upon using drawing views with viewbase command, try to break the drawing views into multiple sheets and add them to external references to avoid bloating of the files and causing performance degradation.
