SolidWorks — Concepts
Vue d'ensemble
SolidWorks (Dassault Systèmes) est le standard de l'industrie pour la CAO mécanique paramétrique. Dominant en mécanique générale, outillage, machines spéciales.
1. FeatureManager (arbre de création)
Document (SLDPRT/SLDASM)
├── Annotations, Material, Planes (Front, Top, Right)
├── Origin, Sketch1 → Boss-Extrude1 → Cut-Extrude1 → Fillet1
└── End
Types de features : Boss-Extrude, Cut-Extrude, Revolved, Lofted, Swept, Dome, Wrap, Pattern (Linear/Circular), Mirror, Rib, Shell
2. Esquisses (Sketches)
- Fully Defined = noir ; Under Defined = bleu ; Over Defined = rouge
- Contraintes : Horizontal, Vertical, Collinear, Tangent, Concentric, Equal
- Smart Dimension : cote simple, angulaire, diamètre, rayon
3. Assemblages (Mates)
| Mate | DDL restants |
|---|
| Coincident | 0 DDL |
| Concentric | 4 DDL (rotation + translation) |
| Parallel | 2 DDL |
| Tangent | 1 DDL |
| Distance | 1 DDL |
| Angle | 1 DDL |
4. Configurations et Design Table
- Design Table : feuille Excel intégrée (Insert → Tables → Design Table)
- Lignes = configurations, Colonnes = côtes + propriétés
$PRP@Material, $STATE@Fillet1 (S=Suppressed, U=Unsuppressed)
5. Equations et Global Variables
"d1@Sketch1" = "d2@Sketch1" * 1.5
"d3@Extrude1" = if("d1@Sketch1" > 100, 10, 5)
6. Mise en plan (Drawing)
- Standard 3 View, Projected View, Section, Detail, Broken
- Model Items : importer les côtes du modèle
- DimXpert : GD&T automatique
- Tables : BOM, Hole table, Revision table
- Export : DWG, DXF, PDF, eDrawings
7. Simulation
| Étude | Usage |
|---|
| Static | Contrainte/déplacement |
| Frequency | Modes propres |
| Buckling | Flambement |
| Fatigue | Endurance (S-N curve) |
| Nonlinear | Grandes déformations |
8. Formats
SLDPRT (natif), SLDASM (assemblage), STEP, IGES, STL, Parasolid (.x_t), eDrawing
Pitfalls
- Large assemblies : >1000 parts → Large Assembly Mode
- Lightweight components : charge mémoire partielle
- Design Table sans Excel : utiliser CSV-based ou API
- Rebuild time : éviter chaînes de dépendances profondes
