# block.atol

Syntax

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 f - desired tolerance value
