Lofting between trimmed surfaces

[Vertex_Assassin]

Hi,

I've been getting some trouble from the shape in this picture:

This is the gearpod under the wing of an A-10, and it's quite hard to
model since it's both organic and contains sharp edges as well (marked
with red) that gradually fade before terminating.

I tried to solve it by doing this:

The bottom and top parts are made of a trimmed surface and there's a
loft between them. I then tried to force the loft into the right shape using
the purple curve as a guide, but it causes the surface to get irregular at
the edges.

Finally, I tried to loft another surface to the open back end, in order to
model the gear pod, the the result is this disaster:

Does anyone knows a good way to model this shape? I'd really appreciate
it

model one side first then trim it back to your red lines. then model the other side and trim it back ... then model the top or bottom as a boundary surface. Its all technique once you learn the tools in surfacing which is the class I teach.

Loft? You sound like your modeling in soliddworks. use a boundary surface. *I got fooled... this is the solidworks forum * When you get down to the math in those surfaces the corner rounds (or what appears to be corner rounds) are probably specific conics with a rho value of .42 to .46... check with your aerospace engineer running the CFD....


...Star trek was killer by the way!
