You can use the tool Checkbox to Show / Hide Objects
in order to create a checkbox that controls the visibility of one or more
existing objects on screen. Alternatively, you could also create a Boolean variable
(e.g., b
= true) using the Input Bar
and make it visible as a checkbox in the Graphics
View by changing its visibility status (e.g., use tool
Show / Hide Object or use the
Context Menu). In
order to use this Boolean variable as a condition for the visibility of certain
objects, you need to follow the steps described below.
