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. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |

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...  ------------- Mike |

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. ------------- "Humans have a strength that cannot be measured. This is John Connor.

Did you check how many linetypes are loaded as I asked previously? Did you run OVERKILL on the drawing? ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |

WBlock out the portions of the drawing you want to keep. Third and last time. Did you check to see how many linetypes were loaded? Do any of them have the letters DGN somewhere in the name? ------------- "Humans have a strength that cannot be measured. This is John Connor.

Hello Rain14, A few months ago, I've had the same problem. A new empty drawing, was already 7mb big. I have found an Autocad Hotfix. With this file you need to overwrite 2 files in your Autocad map. After doing this, you can open your big drawing in Autocad. If you use the command "dgnlspurge", Autocad shall delete all the invisible linetypes. The size of the empty drawing of mine wasn't 7mb anymore but 67kb!! I've add the hotfix file included the readme to this post uploads/476408/AutoCAD_2013_2014_DGN_Hotfix.zip" rel="nofollow - uploads/476408/AutoCAD_2013_2014_DGN_Hotfix.zip |

The linetypes aren't invisible. They are listed in the LTYPE dialog box. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |

It would take you about 5 seconds to check linetypes like I asked (three times). I don't know why you refuse to do so. My participation in this thread is done. Good luck solving your problem. ------------- "Humans have a strength that cannot be measured. This is John Connor. If you are reading this, you are the resistance." <<AutoCAD 2015>> |
