Multi-Select mode enables you to easily and quickly combine and group multiple objects together within your activity file or animation, so that they can be moved or animated as one single object.
Once Multi-Select is active and more than 3 objects have been selected, the Polygon function dynamically appears and allows you to connect the objects selected and display as a multi-sided shape.
For guidance on using Multi-Select mode and the Polygon function, please watch the 1 minute video tutorial below.
