Block

This function pauses to allow all of the previous steps to complete before proceeding.

Most useful in situations where you are unsure of the length of time the previous steps will take to complete, particularly when there are complex animations or voiceovers involved.

This function does not include any parameters.

<animateproperty target="/Roof Support.Height" value="200" duration="3"/>
<block/>
<animateproperty target="/Roof Support.Height" value="800" duration="3"/>

Without 'block', this script would result in the animations conflicting with each-other as they tried to play simultaneously. By adding 'block', the execution won't continue until the first animation completes.
Unlike Pause, the block line won't need to be adjusted if you alter any earlier timings.
