You can also use something like that! ;)
(some more versatile: works with any forms and without edit any codes :)

BoundingBoxCenterMultiple by Michael Gibson https://moiscript.weebly.com/uploads/3/9/3/8/3938813/boundingboxcentermultiple.zip
Can be used to simulate a replacement of objects
By coupling it for example with CopyToPoints or Vclone from MaxSMirnov
http://kyticka.webzdarma.cz/3d/moi/#CopyToPoints
https://moiscript.weebly.com/burman.html (all scripts and commands collected by Burman)

Vclone replaces the vector by the object with size and orientation of the vector!!!



Following with BoundingBoxCenterMultiple & CopyToPoints
Of course a Circle can be used against here a Cylinder! ;)
