The apartment plan is complete as information: drawn, layered, furnished, dimensioned, every number provable. This final lesson turns it from a drawing into a DOCUMENT — something with a name, an author, a date and a frame — and then walks the checklist professionals run before anything leaves their desk.
The frame, sized by the scale rule
Every issued drawing sits inside a border, and the border size comes from a rule you already own. Module 2 taught that text height equals printed height times print scale. The border obeys the same multiplication: it represents the PAPER, so its size is paper size × print scale. This plan will print on A3 paper (420 × 297 mm) at 1:50, so the border is 420 × 50 by 297 × 50 = 21000 × 14850 drawing units.
Create a new layer, TITLE, white, and set it current. REC in a clear area, type @21000,14850 — then MOVE the border (or the plan) until the apartment and its dimension rows sit comfortably inside with breathing room. That rectangle is your sheet of paper, previewed at full scale; Module 4 replaces this trick with the proper machinery (paper space and layouts), and the multiplication you just did is exactly the understanding that machinery assumes.
