 High-speed Drawing Operation Mode Settings
The high-speed drawing operation mode is the mode that is set for DWG.H drawings.
If no DWG.I drawings are used, select the high-speed mode. This optimizes the processing of
DWG.H drawings.
If DWG.I drawings are used, select the normal mode. If the high-speed mode is selected,
DWG.I drawings will not be executed.
