AutoCAD 2013 :: Overly Huge File Size?
Sep 10, 2013
Last month, I was drafting a simple 2d floor plans for my school assignment but the cad file size became huge and started to crash. After consulting my lecturers, I did a few things to attempt to solve the overly huge file size.
1. Redrew the drawing from scratch
2. Purged both old & new drawings
3.Auditted both old & new drawings
4. Saved each floor plan as a separate drawing so as to reduce file size
However, the same problem occurred and the new drawings also became too huge & slow to work with.

I have been using solid body ipts and iLogic code to drive them. I got a little carried away and noticed that the file size was 47 MEG. So I decided to start stripping out items in the model. I stripped out of all the code and all but the initial solid body. There is nothing left but a simple extruded feature. I saved the file and checked the size... 39 MEG.
What is it that could possibly be left in the ipt that would be 39 MEG? I probably deserve this punishment for pushing Inventor beyond its "normal" capabilities.

I am trying to export PDFs of drawings with a high resolution image covering almost an entire A1. I realize of course that the file will be very large but it is much larger than I feel it should, and there are also some discrepancies.
The original image is around 100 MB, but only about half is visible in the viewport, so the PDF should be around 50 MB if there is no compression (only negligible amounts of text and lines besides the image), however if I plot it to a PDF using Adobe PDF, setting the resolution to 300 dpi and medium JPEG compression the resulting file is 150 MB. If I choose 72 dpi and low JPEG compression the file looks very bad and compressed but is still around 40 MB in size. This is far too large considering the amount of compression visible in the image, it looks like a 500 KB file tops.
However if I use the DWG to PDF printer instead of the Adobe PDF I can get a very good looking file at around 2,5 MB. Very suitable for printing, but the compression shows if you look up close in the computer (which is a requirement for these files). The odd thing here is that it makes no difference what resolution I set it to, 150 DPI to 1200 DPI creates the same looking file at exactly the same size. I'd like to be able to create a 2,5 MB file to email and a very high quality file for archivation, but not 150 MB large.
Another odd thing is that if I print another file but with the same type of image (a different facade) with 1200 DPI I get a very high quality file of 40 MB, but if I repeat the exact steps and settings for the first file I end up with a 150 MB file. Of course some differences in the image would account for some of this, but not nearly of this magnitude. I deleting everything from the large file and copying in the content from the small file, and successfully printed a 40 MB file again, so there doesn't seem to be some setting or bug in the file I am printing from, rather something in the original file with the image that I have Xref'ed.
How I would go about creating a very high quality file that doesn't bloat up way more than the original image? A 40 MB file is great considering the images are huge, but I can't get this result consistently.

Is it a proper way of copy some details or layout from DXF files to CAD file? I received multiple(10 files, 2.5mb average) DXF file from source, and they need to input some layout of it to the base CAD Drawing file.My CAD file became huge (around 40mb) when I copy some of the layout from DXF. Do I need to save DXF file into CAD file before I copy some of their layout to get a lower file? I need to send the CAD file to the source for their copy.

i am working on colour-washing an A0 sized scanned architectural elevations drawing, nothing major, but the file size has now gone massive.
it started off as a scanned PDF of 2mb, which i converted to .PSD format and began bucket-filling area's with colour. the .PSD file is now 60mb, and i have flattened the image so there is only one layer?
the problem with it being 60mb is that our plotter hasnt got enough memory to print it.
and i have only coloured half of the drawing so far!
how can i reduce the file size but still keep it in .PSD format?

I am creating a 24"X18" Sign with text and simple graphics.
I set my canvas to 24X18 and the file size is over 2gb.
Should I be doing this in smaller scale to make the file sizes smaller? What happens when I send the file to the sign shop for printing? Will they need the full 24X18, or can I make it smaller but in a format that the print shop can blow up without sacrificing quality?
ALSO, I need to be able to send an example of the sign to my client by email. How can I make a downsized version with a small enough file size to email?

Recently I upgraded fo Illustrator CS6 and found something that is going to screw up my working with clients. The problem is that the .ai and .eps files are having really huge size (67MB on an average). I have used about 6 images (jpeg at 1024x768, less than 1MB each) made them as pattern in the swatches panel and applied on various shapes. The .ai file size is 109MB :O :O :O . Another ridiculous thing is that an art that contains only 3 lines of text plus some circles and squares (3 circles, 2 squares) filled with solid color is around 68MB.
how to reduce the file size without compromising on the pattern quality.

I'm used to working with older versions of Photoshop CS, where I 'just save' exr with no options. This previously resulted in file sizes half that of .hdr. In this latest version if I choose to save uncompressed (which I assumed the old versions of Photoshop did?) the file size is a good 10x larger than they used to be. If I save as zlib or wavelet, they're similar size (a fair bit less than a .hdr).
What did the old Photoshop use for compression? Or how can I find out? I don't remember my old exrs taking so long to compress and save either (with zlib) but I might be wrong.

merging mesh and group from other file (i do this in every new project) i see file size growing (120MB to 700 Mb for example!!)Now, if i try to "save selected" some object,
- from the scene1 in which i've merged object2
or
- from the scene2 that i have merged in scene1
the file saved have the same big size, and if i delete from scene 1, merged object and resave it, the filesize is just a bit less of 700..

I'm laying out some big panels containing smaller images, so I am adding these using 'File>Place'. However, while the empty panel takes up about 70 MB, placing 3MB worth of smaller images makes the file size explode to a whopping 150MB, making it impossible to fill up the entire board. So far, I've seen file sizes of 500 MB, with Photoshop eating up 50GB swap files. what is going on here?
(I'm using Photoshop CS4 on OS X 10.7.3)

I created a short project of two clips of 640 x 480 avi clips with no transitions in VideoStudio Pro X4. I created a media file output and chose the option "same as the first clip." The file created was about 39 MB. Everything was good.
Then I created a media file using the option "Project Properties" and the file size ballooned to about 354 MB, even though I set the Project Properties to the same values as the original clip!!
I need to use Project Properties. Otherwise, when I add transitions, during the transitions the video size changes to widescreen for some reason and the picture looks stretched out from left to right, until after the transition, when the video goes back to 640 x 480.
How can I use the Project Properties option when creating the final media file and not get huge files, or how can I use the "same as the first clip" option and keep the transitions the same size as the first clip (640 x 480) instead of switching to a wide screen mode?

I had a drawing of 64 MB size.Eliminating the single element and no element groups and optimising the block design we could reduce the drawing to 48 MB size.The drawing does not have layer filters, states and is purged completely. It contains links to an external database in which the attribute data is stored.
What else could be done to reduce the drawing size. The drawing response time is too slow as of now.

I am trying to make a huge array of circles (4000 x 12000 or so). I work in microfabrication and need this to make a mask for lithography of a membrane. What is the best practice to minimize the memory usage? I.e. arrays, blocks, groups? I tried making an array of circles one row and 4000 columns then making that a block. Then repeating that block down for multiple rows, maybe 100, then making that a block. Repeating this until I have thousands of them. Is this the best way? It bogs down and gets incredible slow which I am hoping to avoid. I realize that it is inevitable that it will get slow with these huge numbers.

how do i get to create this for such huge prints and what is the settings i have to use in my document, so that when i scale my image up to that size or about it wouldn't be pixelated or starting to be pixelated??

I have a simple angle iron (3 x 2 x 1/4 w/t x 3.00 LG.) .ipt that has 8 thru holes in it file size is 962 MB the file will not open however 3 days ago the file was normal size (160-180KB) and opened fine when i attempt to open this file it eats up about 8 gig of RAM then gives me PmBRepSegment in database then aborts the open process but Task Image Inventor.exe retains the 8+ gig of memory as if a file is open, what caused this file to grow 900 times in size when nothing was done to it?

This problem transfer from one file to another by copying some of it's content to another file. Any command were done just to try to reduce a file but still isn't working.
The problem became serious when each file became at-least 200mb per 2D dwg. Our Tech support said it was a kind of Number virus where it alters the log in each file to have a bigger file size.
Though this happens only in CAD, and certain files/projects were affected. The old and previous file unused where still intact. Only those new ones that we are currently accessing.

I have an image where I desaturated most of the image, with a lot of small brush strokes around an intricate tattoo. I also applied other saturation and hue adjustments. Upon exporting as a jpg, the image size is 3mb, compared to file sizes of 400-500kb for images without so much manipulation. How do I "flatten" the image to get smaller file sizes?

Rendering produces super contrasted image almost white on black (actually grey subject on standard background). Rendering stopped working this morning after running it on full res and size last night. Everything else, even high memory functions, seem to work fine.

I've seen this issue raised by others with no solution to the problem. Here's what I tried:
-lower render output resolution and size
-make new simpler drawing with no materials (same problem)
-open file in MAC 2011 (same problem)
-reinstall autocad MAC 2012
-copy paste drawing into new file
-verify that default lighting and sun are off
I haven't figured out how to restore 2011 or 2012 settings to default.

I've been working on 3D models and noticed when i take a circle and extrude it along a path (usually a spline) it adds a lot to a file size. The objects are used as electrical conductors on power poles. After a few city blocks of this the model file size becomes basically unusable.
So my question is why does extruding a circle along a curved path increase the file size so drastically and is there another alternative to keep the file size down?

I have a file that doesn't have a lot of stuff in it, but the file size seems to be quite large in proportion. Is there a way that I can use DBList, and export the data to a spreadsheet? It would be a lot easier to search through than the F2 way.

I have a drawing that has a filesize of 10meg even when there are no entities in the drawing.There are about 1000 lietypes in the drawing but it wont let me purge them out.These are what are most likely causing the bloat.Some things I have tried without success...
Erase all then purge 3x and audit then purge 3x then audit. Qselect shows no entities in drawing.Save back to acad 2007 and repeat above

I have successfully printed a dwg to a pdf but instead of its file size being 450k it is 1.4 m. This makes sending pdfs via email too cumbersome. It seems that even though the outcome is B&W somewhere along the line "it" thinks it is Color. I noticed that in Page Setup I no longer have the option of "DWG to PDF.pc3".

I got the CAD file 18 MB in size although I do audit, purge, recover, wblock but cannot fix this. The problem was resolved when i created new file in ACAD 2011 and copy all information to.
I mean ACAD 2013 may contain something affect to file size.
Here is the file's link [URL]

By working in millimetres instead of metres will slow things up with my file. My 0,0 point refers to the actual survey co-ordinates which I need to continue to use as regularly share my file with the surveyor and we need to be working on the same 0,0 point. Because I am working in mm 0,0 is therefore further from my drawing that it would be in m. Will changing to metres make a significant difference to me? My file has 34 layout pages and even more viewports which I would have to re scale if I changed the units in my drawings or is there a simpler way of doing this than rescaling the drawing by a factor of 0.001?
