This may help. Go to the General tab in the Solid Edge Options dialog. Uncheck the option for 'Include Draft Viewer data in file' . This will disable data that is written to the file for the purposes of outside viewing.
Hi, I tried turning off draft view option which made very little difference.
I did find the problem, I had in the past created some layouts and in those where some images.
I removed the images and this reduced file size to 1mb, I still found this to be larger than it should be.
Best resolution was to start again.
Draw some lines of the type you want to keep in an old file, open a new file using default files from installation in the templates directory and copy lines from the old file to the new file, change any styles needed and save as new file in the templates directory. When you check file size of new file it is 200kb approx. Use the new file when starting new drawing and size issue solved, In this case.
