Geometrical Feature Help
-
When it comes to aircraft modeling, the push/pull and scale method works well, but not perfectly.
It cannot define geometrical features perfectly. For example: A real airplane has a front face that is a circle.
the rear end face of the fuselage is square. If the push/pull and scale method is used to model it, the rear end will end
up as a scaled circle. Are there any methods that can perfectly represent the real aircraft's geometry? Plans of aircraft don't usually detail panel lines so car-meshing techniques are obsolete. -
You need a loft tool !
Chris Fulmer has a simple one in developement - you need to have the same number of edges in each end face. Say you have a circle with 36 sides the rectangle it will morph to needs each side dividing into 9 pieces...
I've attached an example of a manual method using 12 segments and a square...LoftCircleToSquareExample.skp

You could also use Skin.rb for this very easily (find it in the extensions index on the front page). Darrel (the author) was actually experimenting on this very particular shape while developing it (never really finished though)

One of the first models I DLd from the Warehouse was a model of Air Force One. Looked just like the real thing.
Square to circle is a simpler thing. Start in 2D. Drag out a nice big rectangle. Group it. Draw the circle on the rectangle's face. 12 sides would be easier than the default 24. Draw a square inside the circle, still on the rectangle's face. Draw connecting lines from the circle's vertexes to the square's end or mid points. Delete the original rectangle.
Now into 3D. Double click the square. Use the Move tool to pull it up as high as your plane is long. Scale the circle and then the square, as needed. Group and Qrotate to turn your rocket into an airplane.

I'm sorry, I may not have worded that right. Imagine I dont know for sure what shape the rear of the plane is. I am wondering of there are any successful methods that represent that shape correctly.
-
If you don't know what shape the rear is who does ?
Someone has to tell something to something, or else it can't make it up !

I think I have a solution, but I need a rear, front, side and top view blueprint. I can't find any. Does anyone know of any?
-
http://www.the-blueprints.com is a good place to start but if you google the aircraft name and "three view" you should turn something up.

Ok i will help.
-
start with a circle
-
pushpull it
-
modify the face that pushpull created
-
keep pushpulling it and modifying the new faces until the whole aircraft is finished
I use this teachnique a lot, F22
Hope it helps
