Element: graphic_window.tols[3]
Element: graphic_window.tols[3]numeric
The tolerance for interactive point selection in graphic_window. There are three values corresponding to the three coordinate axes. When a mouse point select operation (e.g. the function pcur) is performed, each of the three coordinates is rounded to the nearest increment of the appropriate tolerance, i.e.
The x ordinate is rounded by tols[1].
The y ordinate by tols[2].
The z ordinate by tols[3].
Tolerance values of 0 suppress rounding for the appropriate co-ordinate. For new graphic windows, the values are 1,1,1.
Set all three tolerances to 0.
set grawin.tols = 0
Set only the Y tolerance.
grawin.tols[2] = 50
