• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Modeling questions...

Hi guys. I'm trying to model a Phenom100 for X-Plane, but the landing gear bays it's a big problem for me. How can I make it? Modeling a new cylinder? P.S: I'm using Blender
And If someone here wants to work in this aircraft with me, please call me in inbox!
Please, can someone help me?!

Objects with compound curves are not easy to model and are best done with splines or nurbs. It is helpful if you have cross section plans but if not study as many images you can find from all angles.

Not in Blender, if you ask me. Unless you are comfortable shaping a surface by moving only its control-points around in space. But that will never qualify as "precise modelling".

True that. I don't know for sure, but I suspect the only available cross-section drawing of this a/c (and its sibling) remains the "OvalLite"-cabin section advertisement from which I derived the basic fuselage of my 300. I have that model on the shelf for years now and I remember modelling that thing was mostly about watching images from every angle, and then pushing vertices accordingly. In Blender, you can create (Shift+A) cameras from a specific angle and, knowing the settings of the real world camera the photo was taken with (flickr, airliners.net & Co often have this data), superimpose the photo on the mesh while you work from the Camera view (just like background 3-view drawings in Ortho front, side or top view).

the landing gear bays it's a big problem for me. How can I make it? Modeling a new cylinder?

If you mean the wing-to-fuselage fairing, and if you have basic knowledge of NURBS curves and surfaces in Blender, create a surface, shape it as closely to the plane's belly as possible, convert to Mesh (Alt+C) and start adjusting loops.

Or you can indeed create a cylinder with enough sections, orient its axis along the fuselage, delete the top half and adjust the loops to fit the shape.

If you want to go the absolute b a s i c way, go to front view, add (Shift+A) a circle of at least 64 verts, delete the top half and make the remaining vertices follow the outline of the belly from the 3-view drawing (front). Go to side view and translate (G) the loop to where the lowermost point of the belly is. Now extrude (E) in whichever direction you want to start with and adjust the new vertices to fit the shape, using a combination of 3-view drawings in the background, photos and guessing. Switch from front to side view as often as needed...

You picked a nice challenge! It's a beautiful aircraft.

Cheers :)

Thank you so much, capt_x! I could finally finish the wing-to-fuselage fairing!
Now there is a lot of work to finish! Soon I'll post some updates here!

Cheers :D
