Select one Solid Body to Merge with another Solid Body

[Anonymous]

Hi everyone,

I am working with three Soldi bodies "Body1 as Boss-Extrude1", "Body2 as Boss-Extrude2", and "Body3 as Boss-Extrude3" and 

I need to merge Body3 with Body2.

My problem is how do I get the information of Body2 so that I can select it and merge with Body3 using API?

My code is here:

 ObjectCollection objCol = default(ObjectCollection);

 objCol.Add(objInvOperationBossExtru.oCompDef.SurfaceBodies[2]);

 ............................

oExtrudeDef.AffectedBodies = objCol;

If I pass the id 2 then it selects the Body2 and gets merge with Body3 but I want to make it dynamic.

Please help me to solve my problem. 

Regards,

I don't know if you need something complex but sometimes simple is easier. why not just make use of the Combine feature?
