By zooming in real time, you control the zoom at the same time you move your mouse.
Using real-time zoom in large drawing files can be memory intensive.
It may be helpful to set the ZOOMDETAIL system variable to a higher value to reduce the number of entities that display during the command. For example, if the value is set to 10, entities with a pixel size less than or equal to 10 become invisible, and when finished zooming in real time, the entities become visible again.
