I have the origin to geometry, I have Individual Origins as the pivot point. All I've done is added the cube, edited a bit to fit the front view then try to add the Mirror. At one point in troubleshooting, I even applied the Location but that makes things worse. The Mirror goes flying off to wrong side many meters. What am I overlooking. The center is so close.
Hi wwrongwright ,
It looks like your Origin is simply in the wrong place.
Origin to Geometry doesn't work, because you want the Origin not in the 'center' of the Mesh, before you are going to mirror it, but at the 'edge' of the Mesh (where your highlighted Vertex is, or at least at that Vertex's X-Position).
Applying the Location is something you should (almost) never do.
The origin to geometry option will centre the origin to the actual geometry, not including what is mirrored. You need the origin to be on the symmetry line.
It is best to keep the object origin at the world origin and model one side of the world grid. This way you can use the positive axis to model and the negative direction will be mirrored.
If you haven't already, or if you need a refresher, take a look at the Blender Basics course.
