>> Hi Alan Thanks for the help. I an trying to make a model airplain I have
made the wing and and fuselage and cant join them !! I still hafe to make the
tail prop and wheels . the prop will nead to turn and the wheels will nead to
turn and then fold into the wing . Is the limit I am runing into 64k faces or
64k vertex or 64k ( faces+vertexs) ? (wht can't autodesk conpile with a long
int) I used deform fit to loft the fuselage I will make it simplier and then
add parts to it this may keep the count doun. I was planing to use autosurf to
make the prop blades . I have been digitizing plans in ACAD-12-autoserf and
dxf-ing them into 3ds. If I boolean the wings on will in stead of join them
will I save on the face count ? This is just a project I picked to learn
modeling with 3ds acad and autosurf and has no teal inport Ben <<
I believe the limit is based on the long integer (16-bit) that both AutoCAD and
3DS use to index vertices in a Polyface mesh. Each vertex has an index from 0
to 655335(?). Each face has 3 long integers pointing to a vertex. This limits
the number of vertices to 64K. I don't know about the limit on the number of
faces but I think that has the same limit for similar reasons. Gary Yost has
said that this is a leftover from the first incarnation of 3DS and would be
changed in the next release. I don't know if AutoCAD has any plans for their
equivalent meshs.
Can you get by without actually attaching the wings to the body? In real life
there would be a seam at the join anyway would there not?

Hi Terry the wings should jone the fuselage with a fillet this can't be dune in
3ds or if it can I don't know how . I it can be dune acad 13 or autosurf as for
not joining the parts I will haft to think about that if ate airplain dosent
move then the must move around it OK Albert but there is still no free lunch

If you build the airplane in either 3DS or Autosurf and add the
fillet, I doubt that you need the wing and body to really be attached
as one object unless you need to use smoothing groups to smooth the
joint between them. There will be a small seam where the faces of
the wing meet the faces of the body because smoothing groups do not
work across objects. This is probably how the joint would look in
real life anyway. If your problem is setting up an animation, you
don't need the wings attached to the body either. Just assign the
wings as children of the body in a heirarchy. Then as you move the
body, the wings will remain "attached". Does this address your
needs?
Hi Terry Thanks I did not know that i could have separt parts thanks for the
help I have a lot to learn about molding Ben
Ben,
Just hang in there Ben. 3D modeling is really problem solving and each problem
you solve helps prepare you for the next one.
