Problem with performance

[Anonymous]

Hello. At the beginning sorry for my English. my problem with AutoCAD 2014 is its slow action during operation. Simple operations occupy 30-40 seconds (eg. explode, scale, trim, lengthen, join). Hardware acceleration, setting autocad program as a priority in the system and limit the details have not given no effect. If possible please help.

Lets start with a few basics:

Hardware specs?

File size?

2D or 3D objects?

In addition to the input requested above, I'd add:

1) Have you installed Service Pack 1?

2) What version of AutoCAD or other computer are you comparing it to to determine that it is slow?

3) Is AutoCAD slow with all drawings, or just some drawings?

RAM: 8GB

Processor: Intel Core i5-3230M  2,6GHz

Graphics card: Intel HD Graphics 4000

File size: 4-6mb or when I stick a part of big drawing(eg. 4-6mb) to new file, performance of AutoCAD is poor again.

Objects 2D

Service Pack 1 installed

When I start a new drawing, AutoCAD is working optimally. The problem is when i must stick something from bigger drawing.

May it be due to frequent saving files?

Have you tried to PURGE and AUDIT the large files you are copying from?  4MB-6MB seems fairly large for 2D objects.  What version of AutoCAD were you using previously that these drawings were working okay on?  I don't see how frequent saving would slow things down unless it's trying to save every minute to a slow hard drive.

I use only version 2014, I tried PURGE without effect. Drawings are large because they're construction drawings.

Did you also AUDIT the drawings?  If that still didn't help, your drawings may just be too big for the hardware you're running them on.  Are you utilizing xrefs at all?  That should help break up your files and give you more control over your layers so they're more manageable to use.  If you're able to upload one of your problem drawings (zipped-up/compressed), that might be helpful as well.

AUDIT detected and deleted 5 errors but without effect. RECOVERALL without effect too.

I send a problematic file.

The problem was that you have a very, very large number of constraints.  If you don't use constraints, I would recommend entering CONSTRAINTSETTINGS and unchecking "Infer geometric constraints" and hitting "OK".

To cleanup your drawing, enter DELCONSTRAINT and select all.  After that, the drawing was very usable for me.  I also was able to cleanup some more of the drawing using the OVERKILL command.  I've attached both drawings for your reference.  If you end up using the OVERKILL version, doublecheck to make sure nothing important was removed, or run it yourself with the settings you select.

Finally, I'll still recommend using separate drawings and/or xrefs to organize your drawings and information so you don't load every line for every drawing of your project when you only want to work on one plan.

Your solutions are great. AutoCAD is very usable now because of DELCONSTRAINT and unchecking "Infer geometric constraints".

Thank you so much for help. Finally the work with drawings will become comfortable and faster.

You're welcome!  Glad it worked.

I tried this and still have a problem.

If you tried that and it didn't work, you likely have a different problem.  I would start a new thread and be specific about what problem you're having and what result you want.  Drawings and screenshots are always helpful as well.
