That’s right, I called it “Junk”.
Recently we have been experiencing excessive bloating of files because somewhere in our project someone has either referenced in a drawing that was opened with Microstation or they have copied in something from a drawing that was used by Microstation.
Below is an example of a drawing that was almost 14 megabytes in size and needed to email it to someone out “in the field” but because of its file size, it was too large to email.
When you start the PURGE command in AutoCAD 2015, you now have the option to purge “Orphaned data.” AutoCAD apparently handles Microstation linestyles and text styles differently so the info that defines these objects becomes “orphaned” and can bloat drawings severely.
Check the box as shown below
If you have any of this purge-able data, the progress of the purge will be shown in the lower right of the AutoCAD screen (shown below)
To purge the “Orphaned” DGN junk from your drawings using the command line version of PURGE command in a script or macro, use the O (letter O) after issuing -PURGE from the command line.
Note: after purging what could be a lot of data from a drawing, it is a good idea to AUDIT your drawing. In the command line, enter AUDIT [enter] Y [enter]

Here is a possible fix for fixing errors that might have occurred during an install of AutoCAD (or any other program) that is preventing you from doing a “repair” or “Re-install.”
Scenario: An issue that has happened at work a few times recently was that a user updated to a new version of AutoCAD but for some reason it doesn’t open. I would then check to see if the files seemed to be copied correctly and tried to manually launch the acad.exe but that didn’t work either. I then went to the computer’s “Control Panel” to do a “Repair” or “Reinstall” of the new version of AutoCAD. The version of AutoCAD seems to be listed in the list of programs but once it is selected, the “Control Panel” says that it can’t be repaired because there was an error during installation.
Once these frustrating steps were tried over and over again, the common fix was to have the user’s machine re-imaged so that a fresh install could be applied. That is, until we found this useful link from Microsoft: http://support.microsoft.com/mats/Program_Install_and_Uninstall
It is a free utility from Microsoft that finds errors of an install that will hopefully allow the program to be successfully uninstalled and then re-installed.
I hope that this utility can help
AutoCAD 2015 now makes resizing model space viewports intuitive and easy.
If you use multiple model space viewports, you’ll love this feature.
A special note needs to be made that the frame of the model space viewports has 2 areas. The area where the plus sign + resides is meant for adding a new viewport. The other area consists of the rest of the viewport edge and has the symbol with 2 lines.
Resize a viewport by simply left-click and dragging the edge of the viewport within the “2 line” area.
The intersection of multiple viewports can be dragged to adjust the size all of the intersecting viewports.
To add a new model space viewport, you can left-click and drag the plus sign + near the top or right side of the viewport edges.
You can also left-click and drag anywhere along the viewport edge and hold the Ctrl key to make a new viewport.
If you would like te delete a viewport, you can simply drag a viewport edge until it collapses.
