3.3.1 The arrangement in the columns must be done in horizontal lines, one for each element. For greater clarity, it is recommended that each element be separated by a thick or thin solid line (type A or B. of the UNE 1-032 standard). 3.3.2 The list must follow the order of the element references. The lists of elements included in the drawing should be ordered from bottom to top, with the column titles at the bottom of the columns. Separate lists of items should be arranged from top to bottom with the column titles at the top of the columns. 3.3.3 Writing can be done freehand, with templates or with the help of any other appropriate means, preferably using capital letters, as specified in the UNE 1-034/1 standard. For all types of writing, including mechanical labeling, see the specifications in this regard contained in the UNE 1-110 standard.
