Default Two objects smoothed together!?

Hi...!

I'm playing with AC3D again, and a new "problem" has appeard.
This time, i want to different shapes to be smoothed together.

Look at the nose on this plane:
http://www.airliners.net/open.file/898405/L/

The front and the middle section has different shapes. I want to smooth the shapes together.

Here's a pic of the two sections which dont fits.



So... how to do that? ops:

Try selecting both Objects and doing either Create Convex Object or Merge. Either way, that will make them one object (there may be a difference in how smooth the transition between the sections will be, since they do NOT match up where they meet right now). Then, smooth the ONE object until you get the visual results you want. Then, if you wish, you can select all the Surfaces that make up what was the purple part of the object and do a Cutaway Object to make it a separate object again.

If the Convex Object or Merge don't get you the right results, consider just extruding a few sections off of the yellow piece and recreating/reshaping the purple piece as an extension of the yellow piece, and then Cutaway Object to separate them into two again.

Actually, I don't think Merge will work, since it's altogether possible to have one object contain a couple of pieces that aren't one contiguous piece. So use either the Convex Object or extrusion strategies to mate them up. Go to Vertex mode, select the Vertices on the ends of each piece where they should meet, and then do the Convex Object; see what kind of "joint" you get. My predicition is that it'll be "messy", and not conducive to a smooth fuselage unit. Extruding from the yellow piece I think will be the best course of action. That purple area doesn't seem like it'll be too hard to recreate. You might want to Lock that, so that the outline of its shape is in view as you work, but you can't inadvertently select it or have it get in the way. Or, just reshape the area from your viewport background 3-views.

I used the "Create Convex Object", and it worked!

But, how does the juncture look? If it looks "patched together", rather than one fuselage, try extrusion. You'll get a smoother, cheaper (in terms of polys) result.

(I'm assuming the purple bit is the very end of a tail, and the yellow part is the rest of the empennage or the entire fuselage. The junction between the tail section and the rest of the fuselage should be very smooth, and any seam imperceptible to the eye, in most cases)
