Spline
With this option enabled, the source will snap to any part of a visible spline curve.
Spline Grid
If you enable this option, you can effectively use an existing spline as a snap grid and snap to the n
th
part of the spline, where n
th
part means the total length of the spline divided equally into n elements.
You choose this value in the ‘Subdiv.’ box. For example, if the spline is 200 units long and you have
entered a Spline Grid of 5, the snapping will be to the nearest 40 unit segment (independent of the
actual spline points).
Axis
Enable this option to snap to the object axis origin of any visible object.
Perpendicular
Here the source is not snapped if the source and target spline curves are tangential to each other, but
only if the curves are perpendicular to each other. This option can be very time-consuming.
Subdiv.
See ‘Spline Grid’.
Quantize
The Quantize settings affect the mouse sensitivity when modeling and editing objects, points, surfaces
and so on.
Move
When positioning objects, points, surfaces and other elements, a small mouse movement can often
result in a larger change than the one you wanted; so, for example, an element that is to be moved by
a couple of units jumps from position 10.374 to position 10.694. To prevent this, use the Move grid.
It is not shown as lines in the view, but has the effect that you can only move an object to positions
that are a multiple of the chosen value. A free or unintentional movement of objects is then no longer
possible.
It is a local grid — it is always relative to the current position. If you entered, for instance, the value
10, an object will always move in units of 10; an object with the position (5,6,90) moved along the X
axis would then move to (15,6,90), (25,6,90), (35,6,90) and so on.
