Creating ribs...?

Hmm, I believe you are the last one.

I looks like you have a transition from the nose cone to the body not accounted for. Try and add some more info in that area. I did just a slanted line and the bump is no more
BTW you can take the section after the nose cone, copy it forward and use the scale tool to match the profile of the wind shield and maybe get much better results.
I maybe misreading the drawing but it looks like the section elevations are not symmetrical with center line. Check that you may need to include the total cross section vs 1/2 you are now -

"More large" is true nevertheless

I'm not blaming curviloft, I suspect its me doing something wrong while creating the ribs
how & with what tools are you using to create the profiles?
.
I simply create square planes in the right dimensions (just like done in the tutorial I linked above) and then use the arc tool to round them off on the corners.

Play with parameters you see on the picture, READ the documentation.
Also for better results make al curves the same account of segments, use BZ tools, right click on a selected curve then choose convert to/ segmentor.

Thanks, I had never tried playing with the parameters, that does help a lot. You mentioned BZ tools, what are they and if thats a plugin, where can I get it?

Read the doc!
Sorry
will read. And thank you! -

All the power of Curviloft is inside changing parameters!
It's like a stand alone program inside SU !

Again, thank you so much!
for the first time, I'm actually happy with the results I get, and its thanks to Fredo's BZ tools you mentioned. This finally solves a huge problem, which had been holding me up for the past weeks. The body still needs some minor tweaks, but it is finally free of holes and bumps all over it:
You sir, saved my day.

You should not be doing that. The drawing gives you section planes a,b,c,d,e etc for the the profiles of the fuselage.They are not symmetrical with is cenetr line and what I was trying to tell you above.

if you just loft the profiles provided on the top view without paying attention to creasing when appropriate.. it gives you somewhat of a more conceptual or futuristic looking shape that you might be able to use as a launching point if you ever get into a more loose interpretation mode..
[edit]..to tie in more appropriately to the thread-- i guess i should add that even though this isn't what you're after, it's an example of using fredo's BezierSpline tools to draw your profiles (uniform B-splines.. order 4.. 30 segments each)..
i could probably edit them in certain areas to get a better mesh with CurviLoft but i don't really see a problem with just lofting what BZspline gives.. -
Looks like a gold fish Jeff, do you
think this could fly? -
@gilles said:
do you
think this could fly?yes.. very well actually..
i mean, it looks like it would fit very nicely into the palm of your hand.. better than a football even (not those spherical things) -
You could had two horns to get a Rhino.
Just kidding.

Yeah, I noticed that the hard way...
I should have used the given section planes, but now I've got it done anyway. Took a little longer but it looks good, IMHO:

I do this sort of thing a fair bit, and without Curviloft, I'd still be trying to finish the first one.
But here are a few tips on what I've learned so far.
When CL creates a bad surface, most usually it is because A) too many vertices, B) Doing too big a surface in 1 go and C) Not enough curve guidance.
A) Cut back on the vertices. Instead of the usual 24 segment circles, use 12. And by all means, try to keep the segment count on opposite sides of a contour the same, and evenly spaced. Not usually possible. When there are big differences, CL will create a very high poly count mesh.
It tries to connect opposite points in parallel curves to the sides of the contours. That will create a myriad of extra lines and new vertices on the contour, and this is very difficult to clean up if you want to reduce the line count.B) Do big surfaces in 2 or more sections, using common contour lines. Do not explode the CL groups till you are done and satisfied. This makes it easier to redo or modify a section, and you can be sure adjacent sections are formed from the same contour lines.
After CL does its thing and you explode it, the contour would almost always have many more segments than before, making the next surface that much more complex. Also, making several sections prevents any complex surface from influencing the next, like at the intersection of the windshield to the body sides and nose of the Huey.C) If your contour makes significantly big changes, and B) didn't help much, then you need to add additional contour control lines between the original contours, and do them as separate sections.
I will first make the surface, that does not form the way I want. Then, I will draw a new contour line midway along a curve that is what I want, using the bad curve as a guide. Then I delete the bad CL surface and CL the section as 2 sections. This will almost always give you the desired end result. When happy, explode everything.I cannot live without Curviloft, in spite of it's (very) few warts.
