sparkyuk Posted April 24, 2015 Share Posted April 24, 2015 Hello All I have received a very large dwg 24,000kb from a consultant and it is slowing my PC down big time, been checking it through and found it was just one of the 3 floors that is causing the large size as if I save just that floor its 19,000kb by its self, after a little searching I found that the AC units on the roof are to blame for a lot of the size they are over 8,000kb just for them alone. My question is why are they such a large size and has anyone got the same block in a smaller size I can change mine to please? I was unable to upload the block here "to big a file" so a picture is the best I can do Quote Link to comment Share on other sites More sharing options...
eldon Posted April 24, 2015 Share Posted April 24, 2015 My question is why are they such a large size and has anyone got the same block in a smaller size I can change mine to please? I expect that the block was off the manufacturers web-site with every nut and bolt modelled in 3D. Why not edit the block so that it only has the outside casing?

SLW210 Posted April 24, 2015 Share Posted April 24, 2015 I would try EXPORTTOAUTOCAD first. If they are blocks, just open in Block Editor and clean them up or even better, put them in a new drawing, Explode them, run Overkill, I usually find Blocks that large are 3D originally with lots of duplication on top of the line work. You may also want to run Audit, -PURGE. There are a Multitude of threads around on reducing file sizes and cleaning up drawings. Quote Link to comment Share on other sites More sharing options...
sparkyuk Posted April 24, 2015 Author Share Posted April 24, 2015 @eldon I think you are correct huge amount of detail that is not needed in this drawing @ SLW210 exploding and overkill did this 41133 overlapping object(s) or segment(s) deleted and now its half the size but still 4,000 kb far to big so I will change the drawing to have a simpler outline of it as that crazy having 8,000kb for one AC unit , just never come across a drawing that large before. I had already tried purge and also ran audit but not much change to drawing size , I see you say use -Purge not Purge when i try this it asks for name is that the block name its asking for and if so how will I find the block name please?

ReMark Posted April 24, 2015 Share Posted April 24, 2015 What about FLATSHOT? Quote Link to comment Share on other sites More sharing options...
sparkyuk Posted April 24, 2015 Author Share Posted April 24, 2015 @ Remark came back with " There are no solids or surfaces that can be projected" ? Quote Link to comment Share on other sites More sharing options...

If you run the commandline version of the purge command, you need to include the hyphen (-purge) & do it as follows... -purge;r;;n;;a;;n;_qsave;;_audit;y;_qsave Quote Link to comment Share on other sites More sharing options...
ReMark Posted April 24, 2015 Share Posted April 24, 2015 Did you explode the block first? Quote Link to comment Share on other sites More sharing options...
sparkyuk Posted April 24, 2015 Author Share Posted April 24, 2015 @dadgad did that and it ended up larger size lol must be me @Remark yes I did explode still the same result. Guys thanks for your very much for your help but I have opted for a simple rectangle instead of that block and file is now down to 2.000kb which is fine Quote Link to comment Share on other sites More sharing options...
SLW210 Posted April 24, 2015 Share Posted April 24, 2015 PEDIT>M>ALL>JOIN will help as well. Did you try -exporttoautocad or aectoacad? I deal with this from time to time, but that one is exceptionally large for a manufacturer's block. Seems like a 3D Block someone flattened, you may be able to get the 2D version straight from manufacturer that might be a smaller file. When I download manufacturer's drawing I get the 3D and the 2D if available. Quote Link to comment Share on other sites More sharing options...
Dana W Posted April 24, 2015 Share Posted April 24, 2015 @dadgad did that and it ended up larger size lol must be me @Remark yes I did explode still the same result. Guys thanks for your very much for your help but I have opted for a simple rectangle instead of that block and file is now down to 2.000kb which is fine If you explode a block that complicated, then each little polyline segment, radius and arc becomes an entity. Thus the increase in file size. I often have to bring in xrefs from architects that are loaded with such blocks. During the xref clean-ip process, I usually draw a rectangle, as you did, around the elevators, generators, kitchen equipment, and so forth, then erase the blocks leaving the rectangles, then -PURGE > ALL. I found one ventilator block similar to yours that had 13 nested blocks inside it. Quote Link to comment Share on other sites More sharing options...
