No problem PaQ!

Actually I think I've just come up with a more efficient way - again do the tapered extrusion about half way up, then select these 2 edges:




Then run Edit > Extend. The prompt will say "Select boundary objects or push Done for mutual extend". You want to do the mutual extend option, so right-click in the viewport or push Done without selecting anythiing else to activate that mode. That will generate 2 lines like this:




Repeat that on the other side so you have 4 angled lines. You can now delete the halfway extruded object, select the 4 angled lines and run Construct > Loft. Under Loft options, set "Loft Style = Straight", and also set a check mark on "Closed". That should generate all the top surfaces with one loft right there. If you want to seal off the bottom to make a solid, select the object and run Construct > Planar to cap off the bottom (for capping, it's a shortcut to select the object that has a planar opening in it and then run Planar - that will also do joining built in. If you build the bottom planar face from a curve you'll have to do an extra step to join it).

Or also another way is if you join in the base line with the 2 angled lines so you have 2 angled triangles like this:



You can then use Construct > Loft and it will build a closed solid as the result.

PaQ - this is off-topic, but I've been meaning to ask you for a while. I watched an anime called Cross Ange Rondo of Angel and Dragon which had mecha and some aircraft that looked very much like something you had posted on this forum a while ago. I wanted to know if you had anything to do with it, or maybe someone was inspired by your work?

Curious!
Sweep + Mutual intersections + Delete is very speedy even forms are some complex! :)



else you have FormZ 8 Free! As its name said it's Free! ;)

You can export in DAE, KMZ, STL so maybe a little conversion at the end will be necessary for input result inside Moi!



its formats import: so make your choice :)

Hi guys,

Hello Michael,

Thanks for taking the time to illustrate additional methods. I didn't know about this mutual extend option, very useful !

Hi omac12,

No I didn't know about Cross Ange Rondo of Angel and Dragon. I would be glad if they get inspiration from my work, but I really doubt it was the case.
(I myself get inspired by lot of other artist work ;))

Hi Pilou,

Yes the Sweep + Mutual intersections + Delete works very well.

I will try to find a picture of the mecha in vehicle mode before transform. I don't recommend watching it it to anyone new to anime as it turned out to be fairly explicit and rather shocking. I'm a mecha junkie so it was fine for me, but it was was way over the top and not suitable for polite company.

Here is a picture that's not too bad even though it could stand to be closer up: http://i.imgur.com/bKMzinP.png
