First script is just for make some random selection!
Not for move something! ;)

It works like this : Draw some many things
Select all
Call the plugin = you have a random selection following your % asked!

Here i use the Transform / Array / Dir for populate the screen



For the second one You must have yet some Styles existing!

script: /* Random Color to something on the screen */ var styles = moi.geometryDatabase.getObjectStyles(); var breps = moi.geometryDatabase.getObjects().getBReps(); for ( var i = 0; i < breps.length; ++i ) { var brep = breps.item(i); var edges = brep.getEdges(); for ( var j = 0; j < edges.length; ++j ) { edges.item(j).styleIndex = Math.floor(Math.random() * styles.length); } var faces = brep.getFaces(); for ( var j = 0; j < faces.length; ++j ) { faces.item(j).styleIndex = Math.floor(Math.random() * styles.length); } }
