f = block.atol
block.atol = f

Get/set the general tolerance for the model, used for:

  1. minimum distance between gridpoints;
  2. minimum area (atol×atol) of sub-contacts;
  3. tolerance to link gridpoints of joined blocks; and
  4. tolerance to select vertices close to the common plane.

(The default = (.0012) × average model dimensions in \(x\), \(y\) and \(z\).)

Returns:f - current tolerance value
Accepts:f - desired tolerance value
