The DWG format is a compressed file format. As with a packed file, the file size displayed in your system (e.g. in Windows Explorer) does not occupy the same size as the plan that you edit in pCon.planner. How much memory an opened DWG file uses can vary, and many factors can determined the amount of memory used.

Program settings and plan content operate together, meaning a direct relationship to the output size does not exist. If the plan includes, for example, a large number of volume models, the DWG’s memory usage from the hard drive would be relatively small. If this DWG were to be opened, and the user defined a high granularity level for the display, the hard drive’s memory usage would be much higher. Rendering time would also be higher for such a plan. On the other hand, a DWG file that contains the same number of objects as it does surface models, would use more hard drive memory than the file with volume models. If opened, however, this file would take up less space.
