Exploded Views 
This information is specific to one or more CAD systems. See the SolidWorks eDrawings functionality matrix for availability information.
You can display exploded view information in your CAD application's assembly documents that you open in the SolidWorks eDrawings Viewer.
For SolidWorks assembly files, when you publish eDrawings assembly files (.easm) that have exploded view information, this information is saved with the eDrawings file automatically. If you save multiple configurations with exploded view information, the exploded view information for each configuration is also saved.
You can use the Explode/Collapse 
tool on the Components tab 
to switch between the exploded and collapsed states. When a model is exploded, you can use all the SolidWorks eDrawings Professional tools, such as Move Component, Measure, and Insert Cross Section, as well as the eDrawings animation, zoom, rotate, and pan tools.
You cannot create an exploded view or edit an exploded view definition inside SolidWorks eDrawings Professional.
To explode views:
Click Explode/Collapse (Components tab) or Tools, Explode/Collapse.
Click again to collapse the view.
