Unknown macro: {alias}
Name
zap — Zap (or snap) to data
Syntax
zap workspace_grid [dif] [adj]
Description
Snap points to a grid. The points are given the value of the surface in the XY-position of the point.
One common use of this command is zapping to sticky_surface. Any grid can be assigned as sticky_surface and many display menus has a checkbox for sticky which means the display will stick to the sticky_surface using the zap command.
Arguments
workspace_grid
dif [kop]
adj [adjustfactor]
The adj argument enables to zap a little bit above the surface in order to display the zapped data (points and lines) without interfering with the surface. The adjustfactor is default 0.2. An increasing value will lift the zapped data higher above the surface.
