Plan question

[fifidibosco]

Hi all and happy new year

These two views of the fuselage, page 3 of Sonerai 1 plan, are they seen from above or below ? (or no matter...)

The lower one should be bottom, with brace below the seat.
With the upper open supporting pilot ingress egress.

Plans are usually drawn where you are looking down from the top. If a different point of view, it’s usually some special detail they are trying to express, and they tell you.

The top view looks like a plan-view drawing (from the top -- by convention -- with a centerline marked on it) and the bottom view looks like a side-elevation drawing.

 

[TFF]

Both tails come to a point so I would not think the bottom was a side. It’s got to be some lofted cad drawing instead of the real plan.

Sorry but my question was not clear.
The upper view is a plan of the upper part of fuselage, horizontal, and the lower is the bottom of the fuselage, horizontal as well. That I wanted to know is if they are seen from above or below.
Basically I want to know how to set the horizontal diagonals if they are like on the drawing below or on the other direction. (or, may be, if they just need to be crossed, whatever the direction)

Standard convention would be viewed from above.

Look from the top. The diagonals are opposite as much as practical for rigidness.

Standard engineering drawing practice is to look down at the top, and up at the bottom.

It appears to be a reversed image from a survey of builder logs.

Well you learn something new everyday.

Yup. Note that the diagonals in the bays aft of the cockpit are going in the same direction on the top and bottom.

Standard engineering drawing practice is to look down at the top, and up at the bottom.

So it's a sort of orthogonal projection...

Yup. Note that the diagonals in the bays aft of the cockpit are going in the same direction on the top and bottom.

... and the diagonals are going in the same direction

Thank you.
