Snapping to Neighbours
When you move a part by hand, NestMaxx helps it settle neatly against its neighbours rather than floating at a rough position. This makes hand-tidying a layout quick and tight.
How snapping works
As you drag a part near others, it comes to rest against them, leaving exactly the spacing you have set rather than an arbitrary gap. You do not have to line parts up by eye: nudge one towards a neighbour and it clicks into a snug, legal position.
Because NestMaxx keeps the proper spacing, a snapped part is not touching its neighbour, so it does not trip a collision flag. The gap you see is the part spacing doing its job. See Spacing and Clearance.
Snapping into holes
Snapping also helps when you drop a small part into the hole of a larger one: it settles into the hole cleanly rather than catching on the edge. See Filling Holes.
When you want free movement
Snapping only guides a part into sensible positions against others; it never stops you placing a part in open space. Drag into an empty area of the sheet and the part goes where you put it.
