Claim 3:
4. The method according to claim 1, wherein a) comprises:
a1) defining a first orthogonal coordinate system having:
as a point of origin, a point chosen by a user in an imaginary support surface located near the area to be coated in a representation of the space using the computer file or in the surface itself,
as height-axis, a normal perpendicular to the support surface or the surface at the point of origin,
as ordinate-axis, the vector product of the height-axis and an axis aligned on a direction of advance selected by the user, and
as abscissa-axis, the vector product of the ordinate-axis and the height-axis;

a2) defining a first normal and taking as its initial value a vector whose direction is the height-axis of the most recently defined first orthogonal coordinate system;
a3) defining in the first orthogonal coordinate system a first point as a point on the surface whose ordinate is the largest within the first orthogonal coordinate system, among the points of the surface;
a4) defining, within the first orthogonal coordinate system, a second point as a point on the surface to be coated located, with respect to the first point, at a first distance measured on the ordinate-axis and in repartition of each nozzle on the print head;
a5) calculating an average normal vector of a temporary strip of the surface defined between a first plane and a second plane perpendicular to the ordinate-axis of the first orthogonal coordinate system and passing through the first and second points, respectively;
a6) comparing the first normal vector and the average normal vector;
a7) if the first normal vector and the average normal vector are identified as being different at a6), then
a71) redefining the first normal vector as being equal to the average normal vector;
a72) redefining the first orthogonal coordinate system taking into account the new first normal vector; and
a73) implementing a3) to a6) again; and

a8) if the initial normal vector and the average normal vector are identified as being equal at a6), defining the portion to be coated as equal to the temporary strip at a5).
