Slow performance dealing with many layers (CPU issue?)

[Anonymous]

Sometimes when working with DXF data taken from gerber data it is actually not possible to work with it because it´s so slow.  The gerber data is from PCB designs so it could be many lines when dealing with some areas that are totally filled. Kind of like using the paintbucket tool in photo edit programs but in this case that area is filled with many lines instead.  

Is there anyway to make autocad simplify the rendering of these layers because I do quite enjoy having them when doing some design decisions? 

For example a roughly 250mm x 200mm, maybe around 8-10 layers took 30 minutes to "MARK, EXPLODE, MARK, COPY, PASTE"..  And with some jobs that is a 10 second task. All depends on how many layers but mostly how they chose to fill up bigger areas. 

Or is my CPU ****? (For autocad 2d purpose at least)    i5-2400 3.1GHz, 4 core. 

16 gig ram, win 10, SSD disc... basic corporate computer basicly. 

I would be grateful for some input on this and maybe personal thoughts on my hardware.

"sometimes" implies randomness, with no discernable pattern to a cause: there is no fix for randomness.

>>>...filled with many lines instead...<<<
DXF files are also exceptionally huge, your corporate basic computer is good enough but most likely not for those types and sizes of files and complexity. Are you specifically saving them to DWG as soon as you can, or are you maintaining the DXF file format while you work in them?

What i do is that I will xplode, fix line with by layer, copy ----> to my dwg file  and then start the real work. 

I´d say it´s maybe only 1 out of 15 that is on the 5-15 minutes for an action.  But many are still not so fun to work with because zooming in and out is a bit laggy and instead of instant or just a few seconds for a copy and paste it could take 30-60 seconds.  

I´d say its not totally random and allmost all of the unworkable files has come from one single customer. But i wouldn´t bet all my money on weither it the layers are big or it´s just drawed in different way. Maybe a combo. 

Why I mention my computer is that i looked the CPU up and on some benchmark test it scored like 3000 points and my 6 year old mid price class home computer scored 7000. Now that does not tell me so much.. But i found it weird that my on a budget bought home computer score so much higher after 6 years when it´s almost retirement time. 

And also start up sequence is like almost 10 minutes for my office computer.

FWIW exploding blocks is never a good idea (unless you no longer need them as blocks and only plan on using very few lines in there): blocks allow the program to operate at a faster clip than a totally exploded DWG file with millions of teeny tine lines everywhere.

1 in 15 is random: 1 in 2 is a major problem: problem files coming from one source simply means the program they use to generate DXF files is the real problem: you two need to connect with work it all out together. Start by finding out what program they use then you two together dig for what options they might use that work better for you.
