Constraints

The Constraint tool enables a marker to be constrained to an object in the 3D scene.  Currently,  markers can only be constrained to object

Applying Constraints

You can constrain a marker to an object, by using the Constraint Tool in the Marker Inspector window:

1. Press the Constraint Tool button.

2. Hover over a object you want to constrain the marker to.

3. Select the object if you want to apply the constraint. Select Cancel or deselect the marker to cancel the constraint tool.

When selecting an element to apply as the parent for the marker, a green dotted line is drawn that depicts if the constraint can be applied or not.  

A green dotted line identifies the selected element can be us use in the constraint. 

A red dotted line indentifies the selected element cannot be used in the constraint.

Toggle Constrained Marker Visibilities

To toggle marker visibility lines on/off for a constrained marker,  select the object and click the eye icon to toggle the marker visibilities on and off.
