Mirroring issue

Hi everyone,

This is probably a simple question but I can’t figure out how to do this in Blender.

I am making a model of a boat. I have made something which works reasonably well for one side of the hull. Wheen I mirror a linked object I have another side so that modifications from one affect the other. The problem is I can’t work out a good way of forcing the two halves to line up properly, I can get reasonably close by carefully moving the two pieces close to each other, but I think there must be a better way to do this.

Any help would be appreciated, thanks

select a vertix from the most inner part of your boat
shift + s , cursor selection
then you have 2 options

  1. press the “Center cursor” button
  2. add an empty to this cursor location , and set the mirror modifier to the empty ,
    the object will be mirrored by the empty location
    ( this way is good when your boat has many parts(objects) that need to be mirrored )

ho and another way
when you are in editmode select all (AKEY)
and move them by right axis (the axis selected in your mirror modifier)
the zoom in ,and zoom in when the mirrored object need to connected

you see when the to parts meets each other
you selected mesh will be freeze (not move for you command) for one second this means you are at the right location

there is another way i think
when moving and pressing the CTRL key ,there is an option to make every step you jump will be to the next vertics location
and not jump by the grid ,i had it once accidentally
any one knows how to turn that on and off ?

This worked, Thanks
