I just started the demo and tried to load a set of gerber files 274X and excellon drill in 3.5 format. Drills are separated into two different files ( plated and not plated ) and generated with the same format ( 3.5). I setup this format in the format settings of the autoimport wizard : gerbers and plated holes are imported correctly while non plated holes coordiantes results multiplied by 10. Here attached you can find the two drill files  


To load those files directly as 3.5 format, please view the following tutorial video (no sound),

For context, here's a quick view of the attached  drill file.

Most drill files are just a lines of numerical values without any format information in the header - and nothing describing the format  (i.e 3.5) to use where to place the decimal point.   AutoLoad is designed to 'best guess' the Drill format (whenever it's not present).  Autoload imports both drill along with Gerber files; which allows AutoLoad to automatically match the drill holes against the imported Gerber files (and determine the proper scale).   However the sample Non-plated Drill file only has a few drill holes which made it harder to match the Drill scale.  Here's a link describing in more detail why the different AutoLoad Drill import results and how to resolve,
