You can use this section of the dialog to limit the selection of geometry to explode.  You can select from the following:

All Visible  

This option will select all visible geometry in the file for use with this utility.

All Selected  

This option will allow you to select the geometry you wish to explode.  With this option selected, select the Pick button and then select the geometry to explode.

Select Layers  

This option allows you to select only geometry located on certain layers that reside in the file.  When this option is selected, all layers present in the file are listed.  You can check the box next to the layer(s) whose geometry you wish to select.  The Select All and Clear All button can be used to assist in selecting layers.

These options allow you to control the array placement of components on the XY plane after exploding.  Select from the following:

Single row along X  

Select this option to arrange all components in a single row in the X direction on the XY Plane.  Enter the Spacing between the components (refer to this value below).

Single column along Y  

Select this option to arrange all components in a single row in the Y direction on the XY plane.  Enter the Spacing between the components (refer to this value below).

Array with fixed distance along X  

Select this option to arrange the components along the X direction but at a fixed distance.  This means that if the next component exceeds the Fixed Distance a new row is created.  Enter the Spacing between components and the Fixed Distance (refer to these values below).

Array with fixed distance along Y

Select this option to arrange the components along the Y direction but at a fixed distance.  This means that if the next component exceeds the Fixed Distance a new row is created.  Enter the Spacing between components and the Fixed Distance (refer to these values below).

Space between components

Orient the Longest Edge

These values are available depending on the Component Placement selection above: Along X   Select this option to orient the decomposed cabinet components along the default X axis as shown below: Orient Along X These values are available depending on the Component Placement selection above: Along Y   Select this option to orient the decomposed cabinet components along the Y axis as shown below: Orient Along Y

These options determine the type of geometry that is created and on what layer they are placed.  Select from the following:

Create both 3D geometry and 2D curves  

If this option is selected, both 2D curves and 3D geometry is created.

Create only 2D curves  

If this option is selected, only 2D curves are created.

Create only 3D geometry  

If this option is selected, only 3D geometry is created.

Create geometry in parent layer  

If this option is selected all 2D curves and/or 3D geometry is placed on the parent layer of each component they were extracted from.

Create geometry in a new layer  

If this option is selected all 2D curves and/or 3D geometry is placed on a new layer with a system generated layer name.

Hide original geometry  
Check this box to hide the original component geometry.  

Place curves on one plane  

Check this box to project all curves onto the XY plane located at the world origin.

Create separate group for each component  

Check this box to group each component separately.

Save geometry colors  

Check this box to save the original geometry colors for each component.

The Flat Panel Layout features are detected and curves associated with these features are created with predefined colors:
