Gents,
For who is interested!

Some work on the crate picture.

To reconstruct the Wester Taurus I must know the position the picture of the crate is taken.
First action is rotating the picture in his normal view position.
Second, I did rebuild the crate, so we can see the complete crate again.
Third action, draw the raster on the top surface so we do have an impression of the distances of the Taurus in the crate.

(I do also use a raster on the bottom of the crate.)

We see the picture is taken nearly over the diagonal of the crate.
The diagonal is normally divided in two identical lengths by the other diagonal.
On the picture we see these two lengths of the first diagonal in the ratio 35 % and 65 %.
With goniometry we can simple reconstruct angles from the point of view; the point the picture can be taken. I combine this method with other methods to reconstruct the right one for every part of the plane.
On the drawing board I do this action with a much better resolution and this action is still a part of the total drawing actions and control of the dimensions and location of components of the fuselage.

So, for myself I do not have to wait until the plane is finished to know how the picture of my Taurus will look like. I can check the dimensions and positions from the same point of view as the picture is taken and make them identical. Dimensions and distances I cannot reconstruct, I mostly can redesign from dimensions of the wings (root for example,), cylinder head dimensions and so on.

Yes, this is a kit that needs some action before I can start building the plane
