The answer to this cannot generalise , as lofting / multi sectional drawing is carried out ONLY for a specific reasons where it is deemed necessary "....in order to convey the relevant 3 D information to the shop floor ".
Although in certain works , ex-boat builders /woodworkers might be employed in manufacture , this is not to say that the designers or their draughting methods came from that industry also ,..in fact much engineering drawing practice came down through the infant automobile & those from locomotive practices .
Basicly , any flowing Irregular , double curvature surface will be described on a drawing by " lofting" practice ....This is simply "decribing the part in a series of grid sections " , in the 3 axis , with dimensions tabulated , simply in order more to keep the drawing Clear & free of confusion .
The draughtsman will use a variety of " splines " at his disposal , to create a flowing curve between specific points .
2 dimensional Airfoil/Rib sections ( often drawn at 1/2 Fullsize) , are normally shown with the offsets given against the dm lines ...the full size template being created from these on the shop floor ....Same with fus. bulkheads , though if of a varying curve , may be more easily tabulated as offsets horiz'ly & vertically .
Structural members are drawn in convensional 3 or more views with Section drawings as required .
LOFTING would apply only to any drawing that describes a 3 dimensional double curvature surface , such as Ally' or cold moulded pannel work ....whether this is applied to a nose shell , for example the FE2b or to the Fuselage shape for the plug for a Pfalz machine .
In each case the purpose is simply to ensure that the full size mould / egg crate jig , or whatever , that is produced on the shop floor as a prototype ,... is an exact full size version of that which was envisaged by the draughtsman , drawn in (often) a more practical reduced scale .
For the draughtsman to create drawings for a Pfalz fuselage at Full Size , would mean him being far too close to see that the lines were Fair .
Thus the primary drawing would be drawn initially at reduced scale ,..( 1/10 or 1/5 scale if metric , or prob 1/12, 1/8 , 1/6 or 1/4 if Imperial ) & then perhaps , dependant on size , transverse sections might be drawn full size in the drawing office ....OR this work might probably be left to the prototype shop floor tool room .
Examples where this would have been employed would be all streamlined Pfalz , Roland , Hawa & some Albatross fuselages etc....Along with smaller Ally' panel components or wooden cold mouldings on other machines as stated above .
The prototype Plug , as produced from the ( scaled up on shop floor to FS ) , lofted (drawn) lines , would be corrected for fairness by use of Splines , skill & "eye" & then all other production plugs would be made to these dimensions .
The outline profiles for the bulkheads frames would then be transfered at the appropriate locations to templates & the prototype drawings ammended as necessary .
Regarding Fokker ,....... or ANY manufactured machine of "Other than streamlined cold moulded, lap strake or other similar construction ",...there is NO NEED OR RELEVANCE to the use of LOFTED LINES .
If I remember , in a letter from Platz , Fokker design ( prototype) drawings such as rib profiles , were done on squared paper (sic) , at 1/2 scale , while others such as fuselages might often be at 1/10 scale for ease of transfer in the prototype shop to full size welding jig boards .
Production drawings eg, Assemblys etc. were done in the larger 1/5 or 1/2 or full scale .
There are some existant Fokker drawings that certainly pre-date the DVII , that are proper engineering drawings .
The Idea of Fokker draughtsmen doing drawings at 1/100 scale is just too silly.
Contrary to the myths still perpetrated , that surround that firm & its personnel ( intentional or not & by whom !) , Fokker did employ competent Engineers & Design draughtsmen ,.... rather than " Welder -- becomes genious designer " ....but that's another story !.
