And with this script you can save your "calculated image" (so no lines aliasingned) at any size following your Memory graphic card!

script: /* Save screen on the ClipBoard*/ var prev_background = moi.view.viewportBackgroundColor; moi.view.viewportBackgroundColor = 0x000000; moi.view.lineWidth = 4; moi.grid.display = false; moi.grid.showXYAxes = false; moi.ui.getActiveViewport().renderToClipboard( 2560, 2560 ); moi.view.lineWidth = 1; moi.grid.display = true; moi.grid.showXYAxes = true; moi.view.viewportBackgroundColor = prev_background;

You can change any parameters!
Past this clipboard on your favorite 2D prog!

It's yet not so bad! ;)

PS I don't know if the PDF export works in this special version?
Tell me when you had try it!:)
