Here you can see that I have a wing for the ship, but how do I make a copy of it so it can be symetrical to the other one. I tried rotating it but It doesn’t give it what I want. Please help
select the vertices of the wing, shift D to duplicate, then M ( mirror ) followed by X ( to indicate the X axis ), or, alternatively, Y, or Z, for the Y and Z axis’s. When it’s duplicated, and mirrored, use the grab widget to slide it into place, and use the ‘remove doubles’ button in edit buttons to merge the pieces. You may have to adjust the influence up a bit, on the remove doubles.
thanks a lot. It works
The whole ship is likely to be symmetrical. Build the whole thing using a mirror modifier so you only have to make one half.
