Snap Settings
Snapping works when moving elements but not when scaling or rotating
them.
Snapping gives you a quick way to accurately place objects in the scene. With snapping enabled, you
can snap elements to other elements, e.g. one point can snap to another point, or a spline point can
snap to the axis origin of another object. The snap will happen whenever the point (called the source in
the following) is within a certain distance of the target; you have control over this radius of attraction.
For example, you can snap the bottom of a sphere to the center of a cube’s top surface.
Snapping overrides the Quantize settings.
The Construction Plane options are independent of snapping and can be changed regardless of
whether snapping is enabled.
Snapping in different modes
Snapping works in the following modes: object, model, texture axis, edges, points and polygons.
Say you have selected several points (or polygons) and want to move them with snapping activated,
when does the snap happen? In other words, which selected point or polygon is taken to be the
source item, i.e. the one that when it gets within the range of the target will snap to it? The item that
is closest to the mouse pointer when you start to move the selection is taken to be the source item;
when that gets within range of the target it is snapped to it and all other selected points or polygons
move accordingly. For example, if you want the edge of a selection to snap, place the mouse pointer
outside the selection before moving. It’s best to try this out to see how it works.
