Ive got 7 .dwg files that ive imported into 1 design layer in a .vwx file.
The 7 .dwg file combined weigh about 23.9mb. When imported into VWX the file is about 120mb. This is not unusual ive previously found that 500kb .dwg files can sometimes weigh about 5-7mb when imported into VWX.
What is strange though is that i cant find out where this extra bloat is coming from, i did a test where i deleted one floor (out of the 7) at a time to see if one of them was particularly heavy - hardly anything changed. (see the results in the images below)
I also tested deleting all the sheet layers that were imported from the .dwgs (the design layer was kept the same) - again hardly anything changed.
I did the same with deleting all the classes (apart from the ones that cant be delted None, 0, dims etc) and put everything into 0 - again hardly anything changed.
I also deleted all the drawings in the design layer - again hardly anything changed, i think the file was 3mb lighter, thats 3mb of a 120mb file - This one was REALLY strange as this is where you would think the most weight in the file is.
I also did a test where i deleted everything - all drawings, classes (apart from 0, none) all sheet layers etc - and the file was still 117mb - again Really odd.
Also whats odd is that if i delete everything then save the file, then add the drawing from the design layer back in from an external file the file size hardly changes at all, which suggests some of the drawing information is remaining, although i cant see where.
Any idea how i can slim these files down / find why they are taking up so much space, is there a command / function to see the size (mb) of each element ?
You can see the results of my tests in the image below
This is what the files look like as .dwgs pre import, see there is a quite a difference in size between them.
I had to blur out the project name in the above image.
