Equal Radius Constraint

In this Task 

• The Equal Radius constraint will be used to make 2 sets of arcs and circles equal to each other.

Before you Start 

• The order in which the concentric objects is selected is important.

Take Note 

• Equal Radius Constraints can be removed by deleting the constraint marker.
• Menu options for the Default menu and workspace, the Ribbon and Palettes are provided directly under the Command Name heading.

Equal Radius Constraint

Ribbon : Insert | Constraint | Equal Radius

Default Menu : Constraints | Equal Radius

Palette : Sketch | Constraints Equal Radius

The Equal Radius constraint constrains 2 arcs to the same radius.The constrained arcs are both updated when the radius of one is changed, either using the Edit Tool or by updating the dimensional constraint.The equal radius relationship between the two arcs is maintained until the constraint is deleted.An Equal Radius constraint symbol is inserted to indicate the relationship between the 2 arcs or circles.

 

The radii shown by point 1 and 2 below will be made equal, as will the radii shown by points 3 and 4. Thus the outer radii will be equal to each other and the inner circles will be equal to each other.

Creating equal radii between the pairs

Select the Equal Radius constraint, then select the arcs represented by point 1, then point 2 shown in the illustration above. Repeat this, selecting the circles represented by points 3 and 4.

The result is shown below.

Arcs equal to each other; Circles equal to each other
