Position the 3d curser where you want the origin the be. In your image above it looks correct, then Ctrl+Alt+Shift+C / origin to curser. Or in edit mode select all the vertices and drag them all to the left. Ensure you have ‘Do clipping’ selected in the mirror modifier settings.
It has done it again, when I do the ctrl + shift + alt + c and click the origin to 3d cursor again it makes it go back to, like what it is in the image in my first post.
But at the moment, it looks like this:
It did work, then I added ‘smooth’ to it then it did that /\
you didnt bring the half close enough to the center. in order for the mirror modifier not to leave a gap, all the vertices that you want joined must be on the center line.
imagine a looking down a mirrored surface lengthwise, objects that are separated from the surface are mirrored to appear to be two separate objects. Whereas abjects that cross or intersect the surface appear to be a single object.
the position (X) of the verts closer to the center must be exactly 0. Otherwise the mirror modifier will do exactly what you see.
select the vertices, press “s”, then “x”, then “0”, and Enter. You will have your verts aligned along the X axis. (But not necesarely in the 0 position) then open the panel at your right (there’s a small + sign in the up-right corner) and enter 0 in the X field (coords).
you can also grab all the verts and slide them along x till they merge. or you can increase the tolerence to merging of verts untill they merge for you.
Ahh done it
Being as soon as the two vertices touch each other they attach themselves; I done it to the ones that were not connected. Therefore connecting them, then I could remodel to make it look normal.
