For the generalansicht (note this just for testing purposes - to see if it could be done, the ship would still need to be 'traced' over, as i am not into WW1 vessels), i saved the picture off the web (dont remember where), it came as a .jpeg.
All i did was copy and paste it into autocad 2005 to see if i could trace over it, no problem, bit blocky close up but workable, to save, i exported to a .bmp format, this i then opened in the MS photo editor and saved it as a .jpeg.
The only reason was to attach to the forum if i need to 'sketch' an idea. not for scale purposes, for printing i can save to a lower autocad format and print on A3 at work, dont know if buying an A3 would be economically viable, by using an A4 printer and create a patchwork of drawings would be better as i already have the A4 printer.
As i said just another option for creating jpeg autocad sketches.
The other ting i remembered that the reason why both halfs of the drawing did not match may be due to the fact that the front half profile may not mirror the rear half profile, if the spacings between the sections is the same, there may be a larger diameter at the back to account for the engine so the front is not symmetrically the same as the rear - but what do i know!! :-[
