1. A forming sheet metal part for a vehicle frame comprising:
a first portion of said sheet metal part being locally heat-softened after said sheet metal part has been formed out,
wherein the sheet metal part further comprises:
a dedicated three-dimensional distortion-absorbing area, defining an internal boundary within which said first portion is to be locally heat-softened after said sheet metal part has been formed out, and
said distortion-absorbing area being dimensioned such that once said locally heat-softening step has been performed, said internal boundary is adjacent to said first portion and encloses said first portion to absorb the dimensional distortions induced by said locally heat-softened first portion, and wherein
said distortion-absorbing area (4) has a height between 2 and 20 mm.
