Dissolving Subassemblies for a SOLIDWORKS Indented BOM

Article by Scott Durksen, CSWE updated June 1, 2012

The SOLIDWORKS Indented BOM style will list all subassemblies as an item, along with all components of the subassembly.  If you have a subassembly that should only list the parts but keep all other subassemblies as indented, you can dissolve subassemblies (or promote components).  Here are 2 methods and their differences:

1.  Dissolve subassembly for a particular BOM

This method will dissolve the subassembly for only one BOM.  Other BOMs that reference the subassembly will still show in the original indented style.

When you select the BOM, you will notice an icon with 3 arrows on the left edge of the table.  Click on this to expand the structure of the BOM.  Right-clicking on the subassembly icon gives you the option to Dissolve.  This will remove the subassembly as an item.

You will notice there is a new icon in the heading row with 2 arrows.  This indicates that the table has been restructured.  To undissolve the subassemblies, right-click on this icon and choose “Restore Restructured Components.”

2.  Promote subassembly components for all BOMs

You have the option to set a assembly file so it will always appear to be dissolved in a BOM if it is being used as subassembly.  This is done by promoting the components.  There are 2 methods to access the same options.  Note that if you make the change in either location, it applies it to the assembly file level.  Therefore all BOMs that reference this assembly as a subassembly will reflect the change.

The first option is to open the assembly file and go to the configuration properties.  From here, there is an option to Promote under the Bill of Material options.

Then the BOM for the top level assembly will show the components only but notice that there is no icon as with the dissolved method.  This is because the change was made in the subassembly level and not in the BOM.

An indication that the subassembly has been dissolved is shown in the top level assembly.  Beside the subassembly in the FeatureManager Design Tree will show “(Dissolved in BOM).”

The same option is available within the BOM itself.  When you right-click on the subassembly icon in the expanded BOM, you can choose “Component Options”.

From here you have the same options to Promote the components of the subassembly.  Changing this updates and saves the settings in the subassembly configuration properties so either method does the same thing.

To revert back to the original indented style,  either return to option to “Show” or right-click on the subassembly in the Design Tree of the Drawing and choose to “Restore in BOM.”
