Happens that if we have a file with lots of information, for example a dgn with 70 layers (levels), in some moment we split it removing some levels to put them in another layer, results that the original file remains the same size. Even we can erase all data and remains the same, although it has no enabled the history.

In this case, I have a map that had almost all information of a county, measuring 17 MB. I deleted almost everything but still measure the same size.

What some people do is to open a new file, called the map for reference and copies it via Fence or exports it with Fence File. The disadvantage of this method is that it may be loosen the historic in case it has being been used, it can also be missed things that were configured in the file via settings / design file.

So the best way is to give a purgative, the term was coined by friends in a course because this process is called Purge in AutoCAD.

• Consider this simple 8 inch square, drawn in QCad. Let's see how the various DXF versions affect the size of the file when it's saved. When saving as an R12 DXF in QCad, the file size is 17,392 bytes. Saving as an R27 DXF, though, balloons file file size up to 101,172 bytes, a 5.8x increase.
• Delete all 3D solids and import them again using the ACISIN command. If AutoCAD Mechanical is available, use STEPOUT and STEPIN instead (layer and colors are better preserved). More file size reduction can be done apart from 3D elements (see How to reduce the size of a DWG file in AutoCAD).

The Brep command erases that history, and the file size shrinks greatly.' Notes from Cadalyst Tip Patrol: When you use the Brep command, the history of the selected solid or solids is removed. That means the original objects cannot be selected, nor can they be modified.

This is done with File / compress. In the Options selection is set what it’s expected to eliminate, including unused levels, line styles, text styles, blocks (cells), etc. /house-of-the-dead-game-download-for-mac.html.

Once chosen, it is applied Compress and that’s all, my 17 MB file got down to just 1 MB. It also erased some objects that seem like ghosts that are seen on the map but can not be touched.

It is possible to configure in Workspace / preferences, and in the Operation option, so that when you leave Microstation it compress the file.
