I am modeling the frame of a bike.

I extruded to separated parts of the mesh, now I want to scale them in y direction, meaning away from each other, what doesn't work because they are not connected and if I set the it to median point (picture 2 the faces get bigger what I don't want. Or you could say I want to move them to the outside but not by hand because I want them to be perfectly mirrored.

Should i just delete have of my mesh and mirror it?

You can enable symmetry in edit mode with the Axis buttons on the top right. Have one extrusion selected and Grab instead of Scale.

  • $\begingroup$ Cant make it work. I go into Edit mode. CLick the Y. Select the faces of one extrusion and move them by pressing g. But nothing it happening to the other extrusion $\endgroup$

  • $\begingroup$ Check if the object origin is in the center of the geometry. It should work if you put the origin in the split of the fork. $\endgroup$

  • $\begingroup$ Yes the origin is in the center of geometry. I just reset it to be sure with Origin>Set Origin>to Geometry. Looking in Y direction it is between the forks but it is obvisously somewhere in the middle of my frame. I just moved it between the forks to be sure but that didnt help either $\endgroup$

    $\begingroup$ if there's a slight difference between the the two parts it may not work any more, maybe before moving the vertices do a Mesh > Symmetrize and choose the good axis in the Operator box (bottom meft of the 3D view) $\endgroup$
