Why are my DWG files so large?

Why are my DWG files so large?

Causes: Corrupt data in the drawing. Data is imported from a DGN file and the original linetypes 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.

Does AutoCAD eat RAM?

AutoCAD (including Mental Ray rendering) is actually fairly light on RAM requirements and Autodesk only recommends 8GB of RAM. However, given the relatively low cost of RAM – and the fact that most users tend to have more than just AutoCAD running on their system – we feel that 16GB is a great starting point.

How much memory should AutoCAD be using?

AutoCAD-based products require at least 2 GB of physical memory (RAM) for working with 2D drawings, and 4 GB is recommended for working with 3D models.

How are DWG files created in non AutoCAD applications?

The DWG was created in a non-AutoCAD application. A large amount of AEC objects or metadata in the file. Data is imported from a DGN file and the original linetypes 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.

Why do drawing files take so long to open?
