If there is more than one Pipe specified in the DETAIL command, or if the isometric for a single Pipe is so complex that it is split over more than one drawing, the plot file will contain several drawings: this is known as a multiple plot file. The user can specify that each drawing is sent to an individual plot file by giving the command

where val is the maximum length of the plotter’s paper roll in millimetres. ISODRAFT will then put as many drawings as possible into each plot file. The AVEVA E3D™ limitation on plotting size is 3275mm2; this cannot be exceeded in either single or multiple file mode.
