In SolidWorks, relations between sketch entities and model geometry, in either 2D or 3D sketches, are an important means of building in design intent.
You can add relations in the following ways:
- As you sketch, allow the SolidWorks application to automatically add relations. Automatic relations rely on:
- Inferencing
- Pointer display
- Sketch Snaps and Quick Snaps
- After you sketch, manually add relations using the Add Relations tool, or edit existing relations using the Display/Delete Relations tool.
Equations create mathematical relations between model dimensions, but outside of sketches.
