Make the change permanent Add the commands that create the heads-up display item (and any associated user interface) to userSetup.mel to have them permanently added to your copy of Maya. Example For example, if you want to show the XYZ coordinates of the selected object in the heads-up display, create a MEL procedure (for example, objectPosition() ) that returns the XYZ coordinates of the selected object. objectPosition procedure global proc float[] objectPosition () { string $selectedNodes[] = `selectedNodes`; float $position[3]; if (size($selectedNodes) > 0) { string $mainObject = $selectedNodes[ (size($selectedNodes) - 1) ]; $position[0] = `getAttr $mainObject.translateX`; $position[1] = `getAttr $mainObject.translateY`; $position[2] = `getAttr $mainObject.translateZ`; Basics 166
