LAYOUTREGENCTL
Specifies how the display list is updated in the Model layout and named
layouts.
IntegerType:
RegistrySaved in:
2Initial value:
For each layout, the display list is updated either by regenerating the drawing
when you switch to that layout or by saving the display list to memory and
regenerating only the modified objects when you switch to that layout.
Changing the LAYOUTREGENCTL setting can improve performance.
The drawing is regenerated each time you switch tabs.0
For the Model layout and the last named layout made current, the
display list is saved to memory and regenerations are suppressed
1
when you switch between layouts. For all other layouts, regenera-
tions still occur when you switch to that layout.
The drawing is regenerated the first time you switch to each layout.
For the remainder of the drawing session, the display list is saved
2
to memory and regenerations are suppressed when you switch to
those layouts
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
layout'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 layouts 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.
