Select Tools -> Transform Tools -> Straighten and Crop. If it is a 45° rotation, set Crop after rotating to "No crop". Click "Ok" | Select Tools -> Transform Tools -> Straighten and Crop. If it is a 45° rotation, set Crop after rotating to "No crop". Click "Ok". | ||
If part of your drawing has been clipped off, you can either drag it into the middle or select Image -> Fit Canvas to Layers. | If part of your drawing has been clipped off, you can either drag it into the middle or select Image -> Fit Canvas to Layers. | ||
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. | We will now ensure the drawing is square and symmetrical. Duplicate the layer and set the transparency of the top layer to 50%.

Next we will check for accuracy of the drawings by comparing it to a reference photo. | 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%. Scale and move the image until its outline lines up with that of the drawing. Note that all photos will have some perspective distortions and parallax, so not all misalignments with a reference photo are bad. | ||
