but when it comes to modelling more organic shapes i get lost pretty quick
Don´t worry, Ron, you are not the only one who feels that way!

ok - checked out the first couple of links
i understand how to set up the 3 views over each other ...
but without some cross sections not sure how to 'skin' or poly the 3d form??
are there plug ins i should be aware of ??
do i need to create at least a couple of key sections from my 3 view amalgamation
also saw a reference to a weld plugin earlier - is that something i should be getting familiar with!!??
back to reread the first post as well
cheers, Ron

Hi manitouguy,
I'm the writer of that aircraft tutorial, and no, you don't need cross-sections to build planes, just 3 views. Cross-sections are needed if you want to be accurate. Yes, you need to download the weld plugin if you want it to be accurate. Firstly, outline the side view and then outline the front view fuselage. Then, group and lock the side view outline. After that weld the front view fuselage outline. Then, move the front view outline to the side view outline. Then, copy it to every endpoint of the side view outline except the last endpoint on the back. After that, move the endpoints on the blue axis so that it connects to the side view outline. Then, unlock and eexplode the side view outline group. After that, just mesh it by connecting the endpoints with lines.

thanks ultimatez -
the three view i have is from online - and i noticed it does have a few indicators for sectional info - last night i battled with it trying to line up the 3 views as ref images on the axis
and then tried offsetting the sections
this plane has such an odd shape - it is hard to even visualize it mentally!!
i will take anothe crack at it today creating more sections
your method ... if the frontal outline changes considerably as you move back through the body of the plane (from skinny nose cone, to fat and round and back to flattened taper) - i am a bit unclear as to how your method accounts for that??
off to try some more - at least i am learning!!!
will see if i can post a pic or two
thanks again all, Ron

You should scale each section to fit into the outline ( of course, it would be much easier to visualize that odd-shaped plane of yours if you could post at least a screenshot )
Take a look at this tutorial http://www.flightgear.org/forums/viewtopic.php?f=4&t=6302&start=0&st=0&sk=t&sd=a -
ok - a few screenshots coming over shortly
Ron -
ok - a few images
no laughing please!!! i have NEVER tried this type of modelling before
i set up the 3 view in typ blueprint fashion - then set up some cross sections as best i could
as you can see the x24a is an odd lump - the brain can't really grasp its final shape ... ! i only have a few internet images and an old mag article, i have a plastic kit coming in the mail which should help
after positioning the sections i then 'hand stiched' the sections one by one (surely there is an easier way?)- faceting them with know knowledge of what i was up to
i then used the smooth tool
now trying to figure out how to build a canopy (it is just wireframe at the moment)
all in all a great exercise and although it looks more like a bag of rocks than anything aerodynamic, i must say i am pleased with my first effort and will continue to work on it as an ongoing 'modelling self tutorial' of sorts - but i am sure we can use this as a good example of what NOT to do
please, fire away comments and criticisms as how to model something like this properly - i want to learn how to do it right and well
oh - and for kicks a pic of it 'mocked up' in a very prelim manner on the beginnings of a titan iii rocket
thanks for looking
Ron

and a couple more - trying to make the bag of rocks like it might actually be aerodynamic ...
because i don't know the proper way - just started laying new facets over the areas which were pinched or lumpy
had fun experimenting on making a canopy too - didn't think i could do it but it turned out nicely (at least to my eyes .. for a beginner)
and did a quick render in idx to see how lumpy it is
now - how would one go back and clean it up and improve the smoothness and polygons??
any help or direction much appreciated
and if anyone wants a copy to examine and critique let me know
cheers, Ron

It seems like you´re making quite a good progress, Ron!
As for the hand-stitching - TIG´s extrusion tools could save you a lot of frustration IMHO http://forums.sketchucation.com/viewtopic.php?p=217663#p217663
Another one worth having in any case http://www.smustard.com/script/SubdivideAndSmooth -
thanks very much for the links - will check them out
much appreciated
Ron
