Feature Tree (FeatureManager)
The ordered list of features that make up a SOLIDWORKS part — every feature reads top-down, edits propagate top-down.
Definition
The FeatureManager tree shows every feature in creation order: sketches, extrudes, fillets, patterns, references, configurations. Reordering features within the tree (drag-drop) changes how the model rebuilds. Suppressing a feature removes it from the build temporarily. Rolling back to a point pretends features after that point don't exist for editing convenience.
Why it matters
Feature tree hygiene determines model maintainability. A 300-feature unstructured tree resists edits and is impossible for another engineer to understand quickly.
Technical Deep Dive & Core Mechanics
From a geometric perspective, Feature Tree (FeatureManager) represents a parametric boundary representation (B-Rep) mechanism within SOLIDWORKS. The underlying geometric modeling kernel—whether Parasolid, ACIS, or a proprietary solver—maintains a strictly ordered history tree (Feature Manager). Each operation stores topological references (faces, edges, vertices) that are re-evaluated sequentially during model regeneration.
Cross-Discipline Collaboration & Handoff
In global multi-office projects, Feature Tree (FeatureManager) is a high-frequency handoff node between diverse software packages. During cross-platform export (for example, exporting SOLIDWORKS drawings to IFC for coordination in Navisworks or Solibri, or converting mechanical STEP files into BIM detail families):
Common pitfalls
- Building all features off Sketch1 — a single broken sketch cascades through the entire tree.
- Naming features by default ('Boss-Extrude1', 'Fillet5') instead of by intent.
- Mass-suppressing features as a 'fix' without resolving the underlying parent-child cascade.
This concept is a core structural element of the SOLIDWORKS drafting and engineering environment developed by Dassault Systèmes. Dassault Systèmes' mainstream parametric MCAD — feature-based modelling, assembly mates, and 2D drawings tightly coupled to the 3D model.
Relevant SOLIDWORKS FAQs
❓ Is SOLIDWORKS available on macOS?
Not natively. SOLIDWORKS is Windows-only. Mac users run it via Parallels, VMware Fusion, or Boot Camp (Intel Macs). On Apple Silicon, virtualisation is limited. The official cross-platform alternative from Dassault is the browser-based xDesign on 3DEXPERIENCE.
❓ What's the difference between SOLIDWORKS Standard, Professional, and Premium?
Standard is the core modelling + drawings package. Professional adds CAD Library, PhotoView 360 rendering, eDrawings Professional, Toolbox, advanced sheet metal. Premium adds Simulation, Routing (electrical/piping), ScanTo3D, Motion. Most production shops use Premium; education usually uses Premium-equivalent.
❓ What is 3DEXPERIENCE SOLIDWORKS vs. traditional SOLIDWORKS?
Traditional SOLIDWORKS is a desktop product, files saved to disk/network/PDM. 3DEXPERIENCE SOLIDWORKS is the same desktop product but cloud-connected: files saved to the 3DEXPERIENCE platform, license tied to a Platform identity, and access to companion cloud apps (3D Sculptor / xDesign, simulation, PLM).
