How to reduce Autocad File size to smaller for all versions ?

AutoCAD is a commercial computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk. AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers. Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal.Since 2010, AutoCAD was released as a mobile- and web app as well, marketed as AutoCAD 360.

AutoCAD is used across a wide range of industries, by architects, project managers, engineers, graphic designers, and many other professionals. It was supported by 750 training centers worldwide in 1994.

There are some of ways to reduce the autocad file size from bigger to smaller i.e from Megabyte to Kilobyte. Due to the file size problem, some common issues will be created, some of them are: 

• Failure to copy and paste elements.

• Hanging for a long time when selecting text with the properties palette open.

• Drawing file takes a long time to open.

This happens when data is imported from a DGN file and the original line types were not mapped or were incorrectly mapped to AutoCAD linetypes. This produces a huge object database in the drawing that cannot be purged with the standard tools. Furthermore, if you copy and paste an entity from an affected drawing into another drawing, the entire database is also copied and the problem is spread to the other file.

How to fix it ?

Open affected drawings in AutoCAD 2015 (or a later version) and use the PURGE command. Be sure to enable the checkbox labeled "Automatically purge orphaned data." This new purge option was added in AutoCAD 2015 as a result of the hotfix being rolled into the program, with the enhancement.

Before that check out this video, this will help you a lot.

Open the Autocad (for all versions), just save the autocad saving format to older versions. This will entirely convert your cad drawings to smaller in size.
