  Not seeing what it is that you are exactly making you can try several approaches:

  1) copy the body using the "move/copy". Then use "delete body" on the first feature. "Delete Body" is a feature rather than just using delete.

  2) let's say you're doing a cut extrude to get the first feature. Try the opposite. Create it as an extrude but do not merge results. This will give you a body that can be mirrored and then use the "subtract" command in the combine feature.

  In other words it's a work around. the parent child relationship cannot be deleted directly once mirrored.

     Thanks for your attention dear cliff, but it doesn't work. When we use the "mirror" command for features there is no "make copy box".
