How to combine or join components together?

[Can Iderman]

Hi,

I would like to join a wing with the fuselage.Currently its only connected by the shape of the foil of the wing. What I would like to do is create a section near the root chord and define that section for example as box, ellipse or some other geometric figure so that

the wing extrapolates to the desired attachment joint. In particular  my fuselage is a circular/smooth box. (The plane is a HWB). Hence I would like to transform the foil shape to one that of a circular box so that the wing perfectly attaches to the box shaped fuselage.

How can I do this?

Thanks

If I understand currently then you just need to creat an airfoil section that is a box or a circle or whatever shape you want and us that as the inner most wing xsec shape.  You can do this by creating an af file and using the file input option for the foil.

But vsp is never going to be able to do cutouts for you of the wing fuselage intersection if that us what your asking.

Good luck, let us know if that's what you were asking

I tried this already and is very complicated and not exact. What my question in general was this:

In OpenVSP you have many components which are modified in some way or another and ultimately need to be attached/combined with other objects. To do this smoothly the surfaces where they meet, should have the same/similar geometry. . I was wondering how to do this?

This should be able to be very exact, you just need to have airfoil xsec defined almost exactly on top of each to create a sudden change in xsec.

However, the functionality you are describing is more of a cad fabrication type of need, and not something that is typically needed in the design or analysis of aircraft.  Manufacturing design likely will always be better done in cad because of the incredible flexibly of cad - which is why it requires extensive training.
