< soapbox > Arrestor wires and all other Model 'features' should be an XYZ offset from the center point of the parent Model's Frame of reference FWIW using LLZ for anything except using user input / output is a step back to the 'dark ages' of the pre satelite era and the advances in Geodysey of the post Sputnik world. IMHO the FDMs should report in XYZ too, interestingly they all use it instead of LLZ internally, and this XYZ is what all FGFS location code should be based on :-) The list has heard me harp on this issue before and has rejected this revolutionary idea but this archaic way of representing position internally in FGFS is IMO a *major* PITA in an otherwise reasonably modern 'Round Earth' simulator. < /soapbox > > With those values we can cheap compute (double valued) positions of these > vertices.
