| If you do not like puzzling with phantom lines and tension, you could force the vertex at an exact location using ''\fmfforce{(0.4w,0.7h)}{v}'', which places the vertex ''v'' at the x position that is 40% of the width from the left, and at the y position that is 70% of the height from the bottom. (Note however that the feynMF manual states it should be used as a last resort only). The alternative is to use intermediate mode with MetaPost which is explained in a [[#intermediate_modehow_to_use_metapost|section below]]. | If you do not like puzzling with phantom lines and tension, you could force the vertex at an exact location using ''\fmfforce{(0.4w,0.7h)}{v}'', which places the vertex ''v'' at the x position that is 40% of the width from the left, and at the y position that is 70% of the height from the bottom.

| It is also possible to use ''\fmfshift'' to shift vertices. This can be used for outgoing point created with ''\fmfleft'' etc., but also internal vertices after they have been frozen with ''\fmffreeze''. | It is also possible to use ''\fmfshift'' to shift vertices.
