Mastercam Highspeed Horizontal toolpath issue - skipping small areas

Horizontal toolpath is a very useful toolpath when you need to clean flat (horizontal) areas on your part. But there is an issue with this tool path, this happens when your part has a small area between large areas, if the area is smaller than the tool radius, the tool will skip that small area. This issue happen when you use bull mill for the toolpath, or using flat end mill but the "floor stock" value is not "0". This issue should be take into account when you use this tool path.
