<SOS> Z-35 needs modeling help

[HundertzehnGustav]

Good Morning Gentlemen.

Wishing to replicate a Destroyer of the 1936 B Class (based on Plans of Z-35) i am more than happy to say that some progress has been made, in shuffling Polygones around. It is not all that hard to get into; with the right References, and a sense for craftmanship...
That said, my Craftmanship is horrible- to say the very least!

I have encountered a snag in Wings3D wich will not let me progress any further than you see on these images.

The new Central Platform is modeled (i try to keep the number of triangles as low as possible), and the Rails are adjusted to suit its naw shape, but as you can see from the image, the whole DD still consists of 3 different objects:
-a part of the rails, wich had to be done from a cube, (easy)
-the platform itself wich was crafted from a Tube (less easy, but still pretty noob stuff, i know)
-the old Hull, from wich the old Central Platform has been "lifted" and then cut away (I deleted the polygones)

The question; simple as ever: how do i properly go about unifying these 3 objects into one?

I suspect that if i can not get them unified, 2Pack3D "chokes on the bone fragments" and refuse to cooperate.
i can turn it into an OBJ file, all right, but i have so far been unable to get it imported into the 2Pack3D Jar program.

Can someone out there offer *hälp* or assistance?

Other progress (NOT SHOWN) has been made on the hulls shape both bow and back, on the subject of mapping, and editing the DAT file in Silent3ditor, ( Thank you Mikail!) so i am hopeful that it is all possible.

Preparations are underway to replicate Z-26 as well, active in the northern waters and sunk in 1942... by british Cruiser Shells IIRC

thank you in advance
Bob
