From: a maze of twisty little passages, all different
I can offer you nothing ready-made, but the website "Wings Palette" (http://wp.scn.ru/en/) contains 43 profile drawings of the Ar234, including B- and C-models. Copy the full-size image and import it into, say, PAINT.NET, where you can resize it. The top view is more difficult. There is one top view of an B-2, but it is drawn at an angle, you would have to turn the image.
DON´T PANIC - IT´S ALL JUST ONES AND ZEROES!
