Snapping

Real conversions are built flush: the unit goes against the wall, the drawer goes on the floor. Both toggles here do that for you while you drag - they pull an object the last few centimetres so its face lands exactly on a surface instead of nearly on it.

Both sit on the Inspector’s Move page, and both apply to dragging only. A figure you type into the Position rows is used exactly as typed and is never nudged.

Snap to van surfaces

What it is. A checkbox on the Move page, off by default.

What it does. While you drag, any face of the object that comes within 5 cm of a van interior surface - floor, wall, roof, rear or bulkhead - jumps flush against it.

Options and limits. It follows the van’s real shape rather than a box approximation. Van walls lean in and roofs are crowned, so an object snapped against one rests on whichever of its corners meets the shell first, which is what stops a corner poking out through a curved wall.

The van is not a boundary: snapping is an aid while dragging, not a constraint, so nothing prevents you positioning an object outside the van or through a wall if that is what you want.

When a group is selected the checkbox reads (whole group) and behaves accordingly: whichever member would touch first decides the snap, and the whole group moves with it, staying rigid.

The toggle is a preference for this session, not part of your design. It is not saved with the design, and it is not on the undo stack.

What it affects. Where a dragged object ends up. Nothing else.

Snap to object surfaces

What it is. A second checkbox below it, also off by default.

What it does. The same 5 cm snap, but against the faces of the other objects in the van, so a box lands squarely on top of a cupboard or flush beside a unit.

Options and limits. Object snapping is the noisier of the two, because a busy layout has a lot of nearby faces. Turn it on for the moment you need it, and off again afterwards.

Three things are never snap targets: the object you are dragging, anything currently hidden in the Object List, and the van’s own cab seats, which are part of the van rather than something you placed.

Both toggles are independent, so you can have either, both or neither.

Both apply to the centre drop handle too, sideways: an object or group dropped near a wall or beside another object lands flush against it. Only the sideways position is snapped, because the height is what the drop itself is deciding - dropping something onto a worktop never snaps it back down to the floor.

What it affects. Where a dragged object ends up. Nothing else.
