Kubajzz,

Excellent suggestion!  I have made the change and have attached the updated script.

Add to the instructions posted earlier:
"Select the mesh you would like to untriangulate."

I ran into this issue a while back. 

I added a little to your code to try to flesh out the problem:
#command("object");

file $file;
string $output;
shape $shape[0];

int $i;

project.curObject.GetShapes($shape);

$output = PrintToString("edges: %d", $shape[0].GetNumEdges());


$file.open("$console", "w");
$file.print("-------\n\n"+$output+"\n\n-------\n");

for $i=1 to $shape[0].GetNumEdges() do
{
  $file.print("Edge: %d Point1: %d Point2: %d\n",$i,$shape[0].GetEdgeIndex0($i),$shape[0].GetEdgeIndex1($i));
} 

$file.close;

I just drew a cube and converted to mesh for a test shape.  The output:
begin script "F:\anim8or_v097b_preview\scripts\edgecounttest.txt
-------

edges: 13

-------
Edge: 1 Point1: 0 Point2: 4
Edge: 2 Point1: 4 Point2: 6
Edge: 3 Point1: 2 Point2: 6
Edge: 4 Point1: 0 Point2: 2
Edge: 5 Point1: 1 Point2: 3
Edge: 6 Point1: 3 Point2: 7
Edge: 7 Point1: 5 Point2: 7
Edge: 8 Point1: 1 Point2: 5
Edge: 9 Point1: 2 Point2: 3
Edge: 10 Point1: 0 Point2: 1
Edge: 11 Point1: 4 Point2: 5
Edge: 12 Point1: 6 Point2: 7
Edge: 13 Point1: 0 Point2: 0
exit script "F:\anim8or_v097b_preview\scripts\edgecounttest.txt"
It appears that the last edge is from point 0 to point 0.  You can probably work around this by just using GetNumEdges()-1.  That is what I have done.

That error can happen when you have forgotten something important.  Did you follow the instructions as given in the tutorial in the first post of this topic?  It is essential that you have set up the attributes properly.

This is the kind of thing that scripts cannot do in Anim8or.  A parametric script is required to return a shape and de-selects anything selected upon execution.  A command script could do this, but one would have to input the amount of rotation manually, and there is no undo of script-moved points.

What are you trying to achieve with this functionality?  Morph targets?  Modeling?  There may be other ways of achieving that effect without this functionality.

Were you using version of 0.97b of Anim8or?  Were you using the command version or the parametric version?  Did you name the path "chainpath"?

Steve,
If I could beg for a single ASL update for the next preview, it would be file.read member function(s).

Here's why:

It would be a work-around for most of the other items on the scripting wish-list. 
(1) One could read and write Anim8or project files allowing one to do particle animation, fluid dynamics, and physics by generating objects and morph targets and scene object placement and controller values, and so much more!
(2) One could simulate parameter passing between scripts
(3) Custom import filters

Once a file.read ability exists, the only thing needed to have robust access to all of Anim8or's modes would be the ability to trigger another script's execution from within a script.  (more begging here)  Even the simplest implementation would be sufficient: completely terminate the original script and begin execution of the requested script.  The file read/write functions can be used to simulate user defined functions ability.

Those two additional functions - file.read and script.execute - would open the door to the development of libraries of script functions like physics, walk sequences, mouth movement, lip synch, etc.

Thank you!

Fluid simulation is very complicated mathematically, but scripts will be written (because I will write them myself) when ASL matures a bit to where scene mode objects, properties, and methods can be manipulated and when object mode objects can access other objects and morph targets.  Realistic fluid and particle dynamics require a combination of shape and movement.  Right now, one could (and some have) written external programs to create Anim8or files to accomplish that as Tanzim mentions above.
