if(`ls -sl`==null)
{
EPCurveTool;
}
else
{
boundary -ch 1 -or 0 -ep 0 -rn 0 -po 0 -ept 0.01 `ls -sl`;
layerEditorAddObjects Head_surfaces;
select -cl;
EPCurveTool;
}

When I run this Mel script is says
// Error: if(`ls -sl`==null)
//
// Error: Invalid use of Maya object "null". //

How do I say to it that if the selection has nothing then just run the EPCurveTool....

Thanks

my usual method:

if (!size(`ls -sl`)) {
}

Thanks a lot I didn't think about using a attribute to test.

no probs.

not sure what you mean by attribute though?

ls returns a string array, size returns how many elements the array has, if it has 0 (ie, nothing selected), and you ! that, your in!
