Sketch Relations Overview

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_Add_Relation_Dimensions_Relations.gif tool, or edit existing relations using the Display/Delete Relations Tool_Display_Delete_Dimensions_Relations.gif tool.
Equations create mathematical relations between model dimensions, but outside of sketches.
