useTrueBBox

layout useTrueBBox boolean { t | nil }
graphic useTrueBBox boolean { t | nil }

Description

Specifies how instance outlines at the display stop level are determined for display.

When set to t, one more level of hierarchy opens. If the instance’s master contains a shape on the layer purpose "instance" "drawing", its bounding box displays as the outline. If the instance contains no shape on the layer purpose "instance" "drawing", the instance’s master bounding box displays. Opening the master ensures an accurate display of the outline, but can affect loading and display time.

When set to nil, the current instance bounding box displays without opening any additional hierarchy. This enables large designs to open and display much faster.
