I have a model with a yellow red and green color mention just to understand. A Green color base on that a yellow and a red color object are placed. Red color object is to under where i have to place the object. I want the yellow color object to be flip to other side where the red cylinder is located. The problem is the yellow object is made of 4-5 mesh and i do not want to join and make the mirror. I just want to flip that complete yellow model to red cylinder position without joining the parts and without mirror modifier. The reason why i do not want to join is later i have to animate the seperate parts. So is there any quick way to flip or addon so that my complete model can flip.blender file here ......
Select the green object, press ShiftS and click cursor to selected.
Change the pivot point to 3D Cursor.
Deselect the green object, select the yellow objects, press ShiftD to duplicate the objects and afterwards press R,Z,1,8,0.
Note that the screencaster in the gif above did not display the Z,1,8 and 0 keys being pressed.
Select green object, press Shift+S and choose cursor to selected. Change pivot center for rotation/scaling to 3D cursor.Select yellow object (all meshes) and either press S,X -1 (to scale it by value of -1 on the X axis, which will cause to mirror the object to the other side) or CTRL+M,X (which will cause to mirror object to the other side)
