The nose of the aircraft should be pointing to the left, if it is not then rotate it using Image -> Transform menu. | The nose of the aircraft should be pointing to the left, if it is not then rotate it using Image -> Transform menu. | ||
We will now ensure the drawing is square. Duplicate the layer and set the transparency of the top layer to 50%. Flip the top layer and move it so that the center line of the top view lines up with that of the bottom layer. Fine tune the position of the top layer until it most closely matches the bottom layer. In this case, there is some slight blurring on the outer wings and tips of the horizontal stabilizers, but it is pretty square overall. Since it is close, I will use this image as is with both layers showing, and I will run the outline of my model down the middle of the lines where there is some slight blurring. We can merge these two layers together now to simplify things later. | |||

Next we will check for accuracy of the drawings by comparing it to a reference photo. | |||
Open the reference photo as a new layer on top of the drawing layers and set its transparency to 50%. Scale and move the image until its outline lines up with that of the drawing. | Open the reference photo as a new layer on top of the drawing layers and set its transparency to 50%.

We can see now that there are some inaccuracies in the engine inlet areas, as well as the very front of the nose. I will leave this photo in as a layer in the master but will hide it when I save a jpg for use in AC3D. I will include the layer again later when I am working on these areas. | We can see now that there are some inaccuracies in the engine inlet areas, as well as the very front of the nose.

We can now crop the drawing to the very edge of the model and clean up extraneous drawings, but be sure to leave in any cross-section references. When cropping, use the select tool with the aspect ration option set to the aspect ratio of the aircraft base on documented aircraft dimension. In this case you can see that this results in the aircraft length being a bit short, but this can be explained by the drawing having a stubbier nose that the real aircraft, so we are all good. | |||
