Q - question

AutoCAD progressbar "Scanning the Drawing..."

A - answer On update operations in AutoCAD or when working with layers, AutoCAD displays "Scanning the Drawing" (DE: "Suche in Zeichnung") in the statusbar. The progressbar may run several seconds or even minutes.

This message indicates a large number of internal drawing tables. You probably have a large number of layers (hundreds, thousands) or layer filters. AutoCAD has to process these tables to update the display of the non-modal Layer Manager dialog.

You can make this processing faster by disabling indication of used (non-empty) layers in the Layer Manager. Use the Settings icon (wrench) and uncheck the option "Indicate layers in use". Or reset the SHOWLAYERUSAGE variable.

We also recommend to use PURGE to delete unnecessary layers (and other drawing tables) and to use FILTERS to erase unnecessary layer filters.
