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:
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.

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 maintain design intent: |
