Table Of Contents

For the Model tab and the last layout made current, the

display list is saved to memory and regenerations are

suppressed when you switch between the two tabs. For

all other layouts, regenerations still occur when you switch

to those tabs.

The drawing is regenerated the first time you switch to

each tab. For the remainder of the drawing session, the

display list is saved to memory and regenerations are

suppressed when you switch to those tabs.

The performance gain achieved by changing the LAYOUTREGENCTL setting

is dependent on several factors, including the drawing size and type, the

objects contained in the drawing, the amount of available memory, and the

effect of other open drawings or applications. When LAYOUTREGENCTL is

set to 1 or 2, the amount of additional memory used is the size of the Model

tab's display list multiplied by the number of viewports in each layout for

which the display list is saved.

If LAYOUTREGENCTL is set to 1 or 2 and performance seems slow in general

or when you switch between tabs for which the display list is saved, consider

changing to a setting of 0 or 1 to find the optimal balance for your work

environment. For additional information about performance settings, see

System tab (in the Options dialog box).

Regardless of the LAYOUTREGENCTL setting, if you redefine a block or undo

a tab switch, the drawing is regenerated the first time you switch to any tab

that contains saved viewports.
