Slotted Through Hole for mounting appears filled instead of drilled

Mulepunch

Hello. I am tryign to make a mechanical non-plated slotted through hole which will allow a device some 'wiggle room' while mounting it on a board. I can't seem to make the slotted through hole appear right in the artwork. It always appears as if it is filled. Below are pictures of how the holes look in the PCB Editor, Pads Deisgner, and Gerber Viewer. Can someone explain what I need to do to make these slotted holes drilled complety through for mounting? Thanks.

     The drill holes can be displayed by Setup - Design Parameters - Display tab on the right hand side turn on Display plated / non plated  / padless holes. There's a color option for the drill holes under Display - Color Visibility  - Display Folder. The drilled slot will need to be outputted as a NC Route file. The gerber file is a pad view so use Manufacture - NC - NC Route to generate an excellon style route file that the gerber viewer will import and you can then see your slots. It's the same principle for Drilled holes, you output a pad view and a drill info. (manufacture - Nc - NC Drill

    Steve,

    Thanks for the tips. I never did get the slots to look right in the the free gerber viewer I was using. But they look right in the PCB Editor, so I sent the artwork to a board house for review with the router file. Fingers Crossed. Appreciate the help.
