SETENABLEPROGRESSIVEUPDATE

Toggles the way geometry is drawn when a large sized drawing is opened or modified.

Type:	Switch
Saved in:	Registry
Initial value:	Yes

This system variable is used to improve the application responsiveness when opening or modifying large sized drawings. Typically, large sized drawings contain a lot of geometry that are drawn when a drawing is opened, and redrawn when a drawing is modified. In a large file, this can take up a lot of time and system resources, and make the application unresponsive.

Setting SETENABLEPROGRESSIVEUPDATE to Yes ensures that all the geometry is not drawn at once. Instead, a simple representation of the geometry is drawn and when the application is in a quiescent or idle state, the geometry is drawn in full. This ensures that the application quickly open a large drawing and is immediately responsive.

When set to No, the application draws all geometry completely. In large drawings, this could lead to the application becoming unresponsive till all geometry is drawn.

Note: This system variable only works for Architecture and MEP objects. AutoCAD objects are ignored.

Yes	Waits for the application to be in the quiescent state to draw full geometry.
No	Draws full geometry when the drawing is opened or modified.
