hello tank you for your response. I know that Fill mode will carve the inner area but the problem is that the size of the rectangle should be 30mmX50mm and the result after carve the inner is 32.3mm x 52.6mm so it’s bigger than 30mm x 50mm.
Hello - I want to add to this thread. I have just had the same experience. I made a box. “Outline” mode did what you would expect - outlined the box. I then ran a second “fill mode” path, expecting to take out the interior of the same box (with a larger bit, for those wondering why do it in two steps). Instead of taking out the interior of the box, it actually made the outline even bigger. “Fill mode” isn’t filling, it’s spilling over the edges…
