Modeling basics · Lesson 5: Patterns and mirrors
Linear and circular patterns, mirrors, and sketch, table or curve driven patterns.
Lesson goal

1. Watch the videos
Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
Video 1▶Linear PatternRepeat in one or two directions, skip instances, vary the parameters.In French↗
Video 2▶Circular PatternRepeat around an axis, a circular edge or a cylindrical face.In French↗
Video 3▶Mirror PatternCopy features or bodies about a plane, with the geometry pattern option.In French↗
Video 4▶Other PatternsSketch driven, table driven and curve driven patterns, and fill patterns.In French↗
2. Key takeaways
Pattern a feature rather than redrawing it: a single change updates all instances.
Instances to skip remove copies without breaking the pattern.
A mirror keeps the part symmetrical by design, even after the original feature is edited.
When the layout is neither linear nor circular, a sketch driven or table driven pattern follows your points or coordinates.
Tip
Preferably pattern the base feature, not its fillets: include the fillets in the pattern or add them afterward.
3. Do the exercise
On a 200 × 100 mm plate:
- create a 4 × 2 grid of holes with a linear pattern and skip one instance
- add a round flange with 6 holes in a circular pattern
- place 5 holes at arbitrary positions with a sketch driven pattern
