A method for generating assembly and/or installation instructions for an object by means of one or more tools (2 to 10), said instructions comprising several display media (11 to 16) of the planar physical media type, or areas of such media, such as sheets or areas of sheet of paper, cardboard or plastic, or of the electronic page or page area type, said object comprising several components (19 to 25, 50, 51) and being intended to be installed in a given location, such as a mosquito net or a rolling shutter intended to be installed at an opening in a frame, said method comprising a generation step, by printing by a printing machine or by generation by computer generation means, of one or more representations (31, 32) of steps for assembling the object and/or installing the object in the given location, on one or several display media (15, 16) in ordered steps, characterized in that it further comprises: a second generation step, by printing by said printing machine or by generation by said computer generation means, of a representation of the tools, on a tool display medium distinct from the display of steps (15, 16), a third generation step, by printing by said printing machine or by generation by said computer generation means, of a representation of all the components not assembled, on a component display medium separate from the display media for steps (15, 16) and tools, a fourth generation step, by printing by said printing machine or by generation by said computer generation means, of a representation of the given location (29, 43) with one or more of its dimensions (X, Y) and without representation of components (19-25, 50, 51) in said given location representation (29, 43) on a location display medium separate from the display media (15, 16) for steps, tools and components, a fifth generation step, by printing by said printing machine or by generation by said computer means for generation, of a representation, for each given dimension (X, Y) represented on the location display medium, of actions to be carried out on one or more of the components (19 to 25, 50, 51) represented in said representation of the given location on the component display medium, by means of one or more tools (2 to 10) represented on the tool display medium, for adjusting one or more of the dimensions of these one or more components (19 to 25, 50, 51) to said given dimension, on an action display medium distinct from the display media for steps (15, 16), tools, components and location. a second generation step, by printing by said printing machine or by generation by said computer generation means, of a representation of the tools, on a tool display medium distinct from the display of steps (15, 16), a third generation step, by printing by said printing machine or by generation by said computer generation means, of a representation of all the components not assembled, on a component display medium separate from the display media for steps (15, 16) and tools, a fourth generation step, by printing by said printing machine or by generation by said computer generation means, of a representation of the given location (29, 43) with one or more of its dimensions (X, Y) and without representation of components (19-25, 50, 51) in said given location representation (29, 43) on a location display medium separate from the display media (15, 16) for steps, tools and components, a fifth generation step, by printing by said printing machine or by generation by said computer means for generation, of a representation, for each given dimension (X, Y) represented on the location display medium, of actions to be carried out on one or more of the components (19 to 25, 50, 51) represented in said representation of the given location on the component display medium, by means of one or more tools (2 to 10) represented on the tool display medium, for adjusting one or more of the dimensions of these one or more components (19 to 25, 50, 51) to said given dimension, on an action display medium distinct from the display media for steps (15, 16), tools, components and location.
