Some scripts to help build rigging fk controls

Hi,

Here are a couple of short tools i wrote to help build fk controls during rigging. Hope you find this helpful.

//treat like selecting target then base shape, icon, then destination jnt
//it puts control at destination, freezes its transformations, groups it with same name,  you need to then unparent it to world 
string $sel[] = `ls -sl`;
{

if(size($sel) == 2){
//no error checking
string $curve = $sel[0];
string $joint = $sel[1];
delete(`pointConstraint -offset 0 0 0 -weight 1 $joint $curve`);
parent $curve $joint;
makeIdentity -apply true -t 1 -r 1 -s 1 -n 0 $curve;  //freeze transformations
string $ctrlPar = `group $curve`;
rename $ctrlPar ($curve+"_grp");//assumes we want to rename it

}

}

//select cvs of all selected curves
string $curve[] = `ls -sl`; //no error checking
string $result[] = {};
for($arg in $curve){
select -r $arg;
selectCurveCV all;//no error checking
$result = stringArrayCatenate( $result, `ls -sl` );
}
select -r $result;



//make world null group on selected using default suffix
{
string $sel[] = `ls -sl`;

for($arg in $sel){
string $ctrlPar = `group $arg`;//should default world axis at origin
rename $ctrlPar ($arg+"_par_grp");//assumes we want to rename it
}

}

cheers,
Nate
