How to constrain two sketch circles

I am trying to fully constrain to circles. I used following constraints

cir and cir1 are two circle objects.

1)          Dim selCenter(1) As Object
              Set selCenter(0) = cir.GetCenterPoint2
              Set selCenter(1) = cir1.GetCenterPoint2
           
              mySketch.RelationManager.AddRelation selCenter, swConstraintType_HORIZPOINTS
             
2)        Dim selCenter1(1) As Object
            Set selCenter1(0) = cir1
            Set selCenter1(1) = cir
           
            mySketch.RelationManager.AddRelation selCenter1, swConstraintType_SAMELENGTH

Now I need to define 'distance between two circle's center points' to make them fully constraint. Please tell me how to do it.

I tried swConstraintType_DISTANCE 1
swConstraintType_DOUBLEDISTANCE 41

but it doesn't define distance constraint. Can you please guide how to do the same.

Thanks in advance,
