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:

Equations create mathematical relations between model dimensions, but outside of sketches.

To create tangent circles:

  • Sketch the first circle using the Circle tool.

  • Sketch the second circle using the  Perimeter Circle tool.

  • Use the tangent icon to place the pointer and sketch the second circle.


To use relations to maintain design intent:

  • Sketch two concentric circles.

  • Add Concentric relation.

  • Circles move together.
