ok so i modeled a fighter jet and used poly split. deleted half and then mirrored it. i then fused the inner edges together.

but my first and only problem…so far… is that when i edit the original half the mirrored half doesn't replicated my poly extrude.

any advice on how to properly mirror or to fix my current prob would help.
much thnx ~ ryan papineau

The problem is that you're editing after the Mirror node. Try doing the PolyExtrude before (above) the Mirror node.

Yep, the mirror node only mirror's anything that comes before it.

Also, if you manually fused the edges after you mirrored, any change in modeling the jet will probably require you to re-fuse the edges, since they will have different point numbers.
