Dupe/Mirror

I half made half of a mesh, it’s the robot’s head from Blender mag. 1.

Now I want to dupe the half, to create the whole head, but I can’t make it so that it fits nicely. I heared some people talking about a neat mirror function? I tried the “Mirror” in the modifiers, but I don’t really get what it does and it’s unclear to me if it can be of any help.

I can Shift+D it and Make it so it fits, and the wireframe looks pretty good, but you can see a clear line between the “two” parts.

Here are some screens to clear it up.

I guess you need to remove doubles to get rid of the seam. (edit mode: w-6)

You can find more info about mirror modifier here: http://mediawiki.blender.org/index.php/Manual/PartI/Your_First_Animation_in_30_plus_30_Minutes_Part_I

They aren’t merged. I could merge them, but it would take pretty long, is there a way to merge two loops, without having to select 2 verts at the time?

Edit: had a bright moment

Merging doesn’t leave any doubles.

Why would I want to remove dubbles? Lemme past the screen with verts.

They are overlapping, I’ve got no doubles. Why would I have em? What did you think I did? Please share.

Edit2: Bummer, the mirror modifier has just the same seam. I want it gone! I think i’m gonna merge the verts one by one, but if anyone knows a quicker way to merge multiple verts to their closest verts, be myguest, leave a message. Thanks for the link to the “Your first anim” :smiley:

Edit3: Holy poepz00rs!

I’ve just found the “Merge limit button” it makes the seam magicly dissapear. Should’ve looked I guess. Thanks for the mirror info!

It seems you got two loops in the centre. Hence “Remove doubles” did not work.

Select both loops (hint: hit loop with ctrl-rmb) and then hit w and Subdivide. This creates a loop between the two loops.

Next we will need to get rid of the extra two loops. Select extra loop and hit x and select “Edge loop”. Do same with the other extra loop. (note: this doesn’t work with multiple loops for some reason. Perhaps it later will.)
