Hi Jacob, when you create the holes, there should be a scope option down the bottom of the property manager:
If you tick the "propagate feature to parts" option, that should then make the feature available in the parts, for when you wish to create drawings or fabrication output.
Hope this helps.
Great replies fellows!!
Thanks a lot
Welcome to the forum. I just wanted to point out that when you make that selection the box for "Auto-select" may be selected by default. It rarely auto-selects the correct components (for me, at least), so you may need to de-select it and select the components manually, or select "All components", if appropriate.
