so i'm a beginner in Maya because i worked with cinema 4d for years now.
My Problem is that i want to Mirror an Objekt by using the "duplicate special" function,
but when i do this i always get this little gap between the parts.

I think the problem is that my "pivot" isn't centered?

but i realy can't figure out how to center this thing with my vertexes on the edge,
is there some kind of numeric window i can just type in the coordinates of the pivot?
would be gerate to get some hints about how to solve this problem!

best greetings,
haiqu
