Hi everibody.

Can someone help me with a solution for this:

---how to import this one
http://forum.openscad.org/file/n20172/Screenshot_%28158%29.png
and use it in this twists  (color"blue") and color ("red") and to have the
shape from color("grey") ? With the command UNION or other command ? And how
to be write it?

color ("blue")
linear_extrude(height = 10, center = true, convexity = 10, twist = -100)
translate([2, 0, 0])
circle(r = 1);
color ("red")
linear_extrude(height = 10, center = true, convexity = 10, twist = 100)
translate([2, 0, 0])
circle(r = 1);

color("grey")
linear_extrude(height = 10, scale = 0, center = true, convexity = 10, twist
= -500)
translate([2, 0, 0])
circle(r = 1);

For more questions just write.

Thank you,Roland.

Schauberger stuff usually can't be done with linear_extrude solely. His
drafts describe fully "organic" shapes, quite difficult to model. Have a
look at the  orginal patent description
https://depatisnet.dpma.de/DepatisNet/depatisnet?window=1&space=menu&content=treffer&action=pdf&docid=FR000001057576A&Cl=3&Bi=1&Ab=&De=1&Dr=5&Pts=&Pa=&We=&Sr=&Eam=&Cor=&Aa=&so=desc&sf=ad&firstdoc=51&NrFaxPages=5&pdfpage=5&xxxfull=1
to see what's it all about.

Hi.
Thanks for reply. I'm beginner in this program and i saw it a way to do
it.I converted this picture with online converters from jpeg to dxf, and
used the little program what you sugest it to me, and i don't succed to
import.Maybe i do it wrong.But what is missing then? The patent i read it a
lot of times and his writings too,now i must to do it and for help i posted
here.If you havean  idea how to do it let me know please. thank you.What do
you think if this coil will be done with hand and after with a 3D scanner
,is posible for that program to do it?  Thank you.

try using inkscape (either import your dxf, or use internal convert bitmap)
and this extension to export to openSCAD.

• http://www.thingiverse.com/thing:1065500
  but all it will do is extrude the shape into 3d. Not sur what final result
  you're going for.
  Could be quite hard to do in any program ??

this Inkscape_to_OpenSCAD_converter_v7 extension is more comfortable for me.
pure scad file output and only simple two files. not need dxf in the middle.

Hi.

  Thanks for reply. This program help me.

Questions :

1. can please help me to combine your program :

linear_extrude(height = 100, scale = 1.5, twist = 2360, slices = 200)
difference() // replace this by: import("scan.dxf");
{
polygon(Egg(r=10, f=1.4, o = 1));  polygon(Egg(r=9, f=1.4, o = 1));
}
function Egg(r = 10, f=1.3, b=10, o=1) = [for(i=[0:359])  [frsin(i),
rcos(i + cos(o*i)*b)] ];

with this 2 programs :

color ("blue")
linear_extrude(height = 4,scale = 0.6, center = true, convexity = 10,twist =
-100,
slices=10,
height = 6, center = true, convexity = 10, twist = 100)
translate([4, 3, 0])
circle(r = 1);

color ("red")
linear_extrude(height = 6, center = true, convexity = 10, twist = -100)
rotate([180,150,0])
translate([5, 3,30])
circle(r = 1);

2. is a posibility to can modify the EGG from your program ( i succed to
   find and modify it until a point,but just the half of the egg the pointed
   side) ;
   -----  let say : to do the concave side-s , to make the egg longer,
   shorter, higher, concave( like in color -blue and red ) ?

3. How can i join the programs from question 1 and 2 , and other parts to
   it,in a string ?

4. If this coil is ready in this program,can i transfer it to the cnc? Or
   needs more transformations?

   I try it myself with your program to add it to this blue and red ,but
   is still missing something,which for me is imposible now to understand.
   I do it this coil until a point in FUSION 360 and a friend ( like
   you is trying to help me there),but in that program is missing some commands
   to achieve it.

Thank you for your time for me,Roland.
