Trouble with a vector...?

[kamron-ewing]

Im having a bit of trouble with my code all of this here works in that it selects the cvs of a selected curve and then finds there locations and sets them up into vectors but when i try to apply these vectors in a way where it will create a curve based on them it merely creates a curve at each cv point.  Why is it not creating the ep curve as asked???

string $sel[] = ls -sl -flatten;
string $cv = select ($sel[0] + ".cv[*]");
string $fit[] = filterExpand -sm 28;
int $si = size ($fit);

for ( $j=0; $j< $si; $j++){
   float $bunk[] = `xform -q -ws -t $fit[$j]`;
   string $trax = ($fit[$j] + $shit[0] + "\n");
   string $tray = ($fit[$j] + $shit[1] + "\n");
   string $traz = ($fit[$j] + $shit[2] + "\n");
   vector $cords=<>;
   curve -ep $bunk[0] $bunk[1] $bunk[2]
}

select -cl;

I would appreciate some help in this matter.  When finished it is supposed to copy a curve then create a button for easy recreation of that curve in my rigging.  I of course haven't written the GUI nor the error checking, but thank you.

you're not creating a curve if you keep the curve command inside the for loop. You could create a string outside the loop, then append  -ep $bunk[0] $bunk[1] $bunk[2] to it and execute the command you constructed when you're done.

Here's how  I usually do that:

string $strcmd = "curve -d 3 ";
for ($i=0; $i<=10; $i++) {
$strcmd += (" -p " + $i + " 0 0" );
}

eval $strcmd;

Thank you getting the curve outside of the loop like this did indeed work and fixed my work impedment now i can move on to rebuliding the curve and correcting the pivot control location.

Few things:

all curves are at all times cv curves. even ep ones. Bow ep ones can describe many curves. So a curve with given eps CAN have several different shapes so to do this flawlessly one need to query both curve degree, point weights etc etc. and make  cv curve of that kind.

You are however overlooking one of the simplest ever things (so fundamental that most people overlook this, and it works on almost every program ever devised). If you want to copy a curve for later reuse. Then just export that particular node to a maya file. The just import it when you need to load it anew. Even better this make making a gui simple as you just scan the contents of a given folder and thats it. Now if you ever want to extend out form curves to meshes or surfaces. its as easy as 1 2 3 to extend because theres no need to do anything. (this is by the way how Maya's copy paste works, it just a temp file)

Constructs like:

float $bunk[] = xform -q -ws -t $fit[$j];
vector $cords = <>;

Can simply be written like:
vector $cords = xform -q -ws -t $fit[$j];
I newer Maya's (no idea when it was introduced, pretty fare away tough). Maya just knows how to typecast this, tough there's NO MENTION of this fact anywhere

I didn't just want a duplicate tool but more specifically a tool for copying Control Curves that i then again can call upon again whilst rigging.

Thats the same thing.
