 Topic: Why my file CAD size was big
Posted: 28.Oct.2014 at 05:25 |
Dear All,
I'm new here and need some help. I have problem with my File CAD. When i try to save my file, the size change very big. Example when i open its only 10 mb but when i save it. its turn to 25 mb.
Can anyone answer what happen to my file?
I actually use a different computer to open that file and my friend also can't open the file if i save it.
If i use a computer with a different bit, can it change the file size too?
Please help me,
Thanks

Hello Rain14, if your friend can't open your file it's maybe because he uses an other AutoCAD release ( AutoCAD2008 and not your AutoCAD 2009 ).
Do you PURGE your files ?
Do you SCALELISTDELALL ypur files ?
If your files are 25 mb it's because of the complexity of them, are they 2D or 3D ?
If they are "only" 2D you could simplify them by using BLOCKs.
If they are 3D you can also use BLOCK.
If you explose 3D or use FLATSHOT you will have to use OVERKILL on the 2D object that you create.
When using OVERKILL you will erase dashed lines in double with continuous lines and I sujest you separating them with QSELECT before.
Tell us it this helped or not.

I think you should take a look at the number of linetypes being loaded.

Got the same problem in one project before but after searching for long time I found the solution to reduce the cad file but I still have same problem after a while files keep bigger after adding changes & modification ,then I had to go back back to my reducer solution at least it come lower from 10 mb to 1 mb.  . step 1: try to save as your file to dxf file lower version note: change the name_ sample 1.dxf (don't panic it will be more bigger) step 2: (PU)Purge your file try to clean it after CTRL+S quick save then close. step 3 : Re-open your file 1.dxf and save it back to the original file dwg name sample 1-project.dwg  PROBLEM SOLVED!!!Repeat the procedure you will notice that from 100% bigger to absolute 20% reduce file .Hope I save your day thanks to CAD Forum...  |

If you are going to use the purge command then utilize the command line version which is -purge and purge Regapps first. Repeat the command, -purge, but this time do a purge > all. Run an Audit of the file too and have AutoCAD correct any database errors it finds.

Did you check how many linetypes are loaded as I asked previously?
Did you run OVERKILL on the drawing?
