Can you group multiple parts into a folder in the assembly tree in SolidWorks?

Short Answer

Yes — in SolidWorks, you can group multiple parts into a folder in the assembly tree using the Add to New Folder command in the FeatureManager design tree. This is the most common professional method for organizing large assemblies and improving tree readability. Limitation: folders only organize components visually and do not create a subassembly.

What You Need to Know Before

Warning: moving components into a folder does not change mates, bom structure, or assembly hierarchy. A common mistake is assuming a folder behaves like a subassembly, which can lead to confusion when managing suppression states or drawings.

How to Group Multiple Parts into a Folder in the Assembly Tree in SolidWorks

• Command: Add to New Folder

• Shortcut: None

• Quick Steps:

  1. In the FeatureManager design tree, Ctrl-select multiple parts or components you want to organize.
  2. Right-click the selected components, then choose Add to New Folder from the context menu.
  3. Rename the folder if needed, and optionally drag additional components into it later in the tree.

Variables & Settings

• Key Setting: FeatureManager design tree folder name and expanded/collapsed state

  This affects assembly navigation only. Keeping folders collapsed can make large assemblies easier to manage, but the folder has no effect on mates, BOM quantity, mass properties, or file structure.

Why it Fails

• Cause 1 (Geometry): components may be inside patterned or mirrored component groups that limit how they can be reorganized visually in the tree.

• Cause 2 (layers/Locks): if files are opened read-only or controlled by PDM state restrictions, tree edits and renaming may be limited.

• Cause 3 (Command/Logic): users often expect a folder to function like a subassembly, but folders are only organizational containers and do not change assembly behavior.

Quick Fix & Best Practice

• Quick Fix: if you need functional grouping, use Form New Subassembly Here instead of Add to New Folder.
• Manager’s Verdict: use folders for visual organization in large assemblies, but use subassemblies when you need motion control, BOM structure, or reusable grouped components.
