I’ve been trying to use blender after using wings3d but I can’t find a virtual mirror like tool. i.e. select a face and have the model mirrored about that face so that I don’t have to edit two halves.
Asolutely. Can be a bit of a pain to line it up at first. Easiest way is to add a modifier of type “mirror”. The clipping option makes the middle seam stick as one. It’s under Editing (F9) panels.
