I am trying to switch to Houdini from XSI.
In XSI I could do something called symmetric modeling. Cut an object by half, and mirror it. And edit just the source half, then I get exactly same result on both sides automatically mirrored without any concern.
I tried to do this with Modify - Mirror, but it seems the mirrored object is disconnected from source object, so editing on source object won't be applied on the mirrored object automatically.
How can I make it to be applied automatically?
