civil 3d reduce drawing size
When working with AutoCAD, sometimes y'all tin see that your files get unusually large. It may slow your arrangement down and it might crash the system. Yous might want to effort to reduce the file size.
Other reason why you desire to reduce the file size is because yous need to transport it as attachment or upload it.
So let's see what we can exercise to reduce AutoCAD file size.
Audit
Audit doesn't reduce file size. But it is recommended to exercise file audit before we continue with other process. Information technology will maintain the drawing integrity and fix errors that might foreclose us to remove unnecessary objects.
If y'all are not familiar with audit, yous can run it by typing Audit at control prompt then press enter.
Or you can admission AutoCAD menu (the big red A) > Cartoon utilities > Audit.
Purge
After you audit the cartoon you can run PURGE. You can type PURGE at control line then press enter. AutoCAD will open up a dialog box like below.
As you can meet in the listing, you tin can purge or remove unused objects. Block definitions, styles, materials and layers.
Remember, if you still need to use them, do not purge all items.
Purge regapps
Regapps stands for registered applications. To purge regapps y'all demand to blazon –PURGE (with the – prefix) then enter. Type R for regapps then enter again.
In many cases, purge regapps can significantly reduce the file size.
If you lot desire to know more nearly regapps, check this post by Donnie Gladfelter: Ditch excess RegApps & Speed Up Your Drawings.
WBLOCK
Purge removes unused objects. WBLOCK works differently. With WBLOCK y'all choose objects that you need and save it to a new clean file. So you left the backlog in the origin file.
You can activate WBLOCK by typing WBLOCK then press enter. Using this command is very similar to creating cake. This command was originally for create block as external DWG, simply we tin utilize it for this purpose as well.
I would recommend you to select but objects yous want to write to new file. Do not type ALL when AutoCAD ask you to select objects.
AutoCAD issues related to file size
If yous accept washed all above but y'all remember your file is still unnecessarily big, it might exist because there issues with your file. There are also some known issues related to this bloated file size. Some famous issues are:
Calibration list issue
This issue was plant in AutoCAD 2008, when Autodesk first innovate note scaling. You can have so many calibration list in your drawing, especially if you work with reference file.
You can clean up the scale listing past using available clean upward utility.
You can download scale list clean up utility for AutoCAD 2022 hither.
DGN Lineweight
Some other issue that can crusade DWG file to increase file size is considering DGN linetype issue. This can happen if you work with DWG that contains DGN linetype.
There is hotfix bachelor for this issue, and the hotfix too provides clean upwards utility.
You tin can download DGN hotfix hither.
Retrieve to read the readme file because you need to manually copy files earlier you tin can run the utilities.
Other optimization
Thank you for all emails and annotate I received after I published this article. These are some more things that y'all can practise:
Tips from Jacob Dunkelman:
- Delete layer filter, on same cases, after DLF the file size was reduced to v% from its original size
- Delete groups. Mainly the unnamed groups. Some add-on are heavy users of unnamed groups
- Delete layer land managers
- Detach unreferenced XREFs and IMAGES
Tips from Billy Stang:
Use the "overkill" command to reduce file size and clean up a drawing.
Tips from Tawfik Shehata:
Employ of blocks for repeated instance of objects.
Remove unused annotative scales from objects. To foreclose applying unnecessary annotative scales to objects, brand sure that ANNOALLVISIBLE is prepare to 0 and ANNOAUTOSCALE is prepare to -4 these 2 system variables are set per layout/model.
How big a DWG should be?
A drawing file may exist big if information technology's a complex drawing. Especially if you work with 3D model. Nonetheless, if your cartoon is quite uncomplicated but the file size is more than 10 MB so something might be wrong.
If you lot have done all above procedure but your file is still large, so it might exist because the complexity of your cartoon.
Are in that location any other issue that y'all know tin increment the file size? Or is there any other method that we can do to reduce file size?
Share your experience with u.s. hither!
