When converting SW drawings into a DWG format, why does the file size increase so much? Is there a way to keep the DWG file size to a minimum.
You could always run the "purge" command in autocad to get rid of any blocks/layers/other junk that you don't need. That will help some. That still seems like a pretty large file though. Do you happen to have a jpeg or bmp image in your solidworks title block? That could be a culprit for a large file size.
I just did a quick check on one of my drawings in SW20010 and the file size decreased. What version of SW are you running?
So what kind of size increase are you seeing? I took a 1.69mb solidworks drawing file and after I saved it to .dwg format the size went down to 399kb.
I talked to the co-worker who prompted me to post this. It did in fact REDUCE in size as you have stated above. However, he is wondering if there is a way to further reduce the file size. Case in point. The original SW drawing was a 31 MB file. Once saved as a DWG type file, it reduced it to 16 MB. The problem comes when he tries to e-mail the drawing out. Our customer inbox has a 10 MB max. So if there are steps we can take to reduce file size, we are all for it!
Would the customer accept a pdf file? It would probaby save to be much smaller and 16meg.
I opened the drawing a screwed around a bit. There was a iso-view of the assembly up in the corner. Lines everywhere. I deleted that and saved it. The file size went from 16 MB down to 6 MB. So A/C must not care for SW's busy iso views!
Have you tried compressing the file using ZIP, RAR or 7ZIP?
CAD files can be quite large but generally compress well - I have seen a 10mb IGES file zip down to less than 1mb. Same applies to SolidWorks parts and I would guess this would apply to DWG and DXF files too.
