// EJL Finish Loop v1.0

// DESCRIPTION:
// 
// When building edgeloops or re-doing topology on a mesh, it can become
// time consuming to actually create edgeloops by hand with the split polygon and/or edge extrude
// tools. With this script you can cut that time in half.
//
// HOW IT WORKS:
//
// This script looks for 'open' patches on your polygon mesh, fills the hole and then attempts
// to create logical divisions by first triangulating the newly created poly face and then 
// quadrangulating. There is room for error, so always check the newly created divisions.
//
// HOW TO USE:
//
// This script works in object or component mode. In object mode select the object and execute
// the script (will operate on all holes). In component mode you'll need to select one or more
// border edges of the hole you want to finish, and then execute the script (operates on
// only that hole). 
//
// Make sure that the hole(s) you are going to work on have completely closed borders, otherwise
// the procreedure will fail or provide undesireable results.
//
// INSTALLATION:
//
// Copy script in to your scripts directory (i.e. /User/maya/7.0/scripts). In the command line
// or script editor, type the following line (which can be made in to a hotkey):
//
// If you have any questions or comments, please send me an email at mezza550@gmail.com

// Close empty loop

polyPerformAction polyTriangulate f 0;
