angular_tol

0 0.000000<integer tolerance>
Sets default angular tolerance dimensions. The integer sets the number of decimal places, and the tolerance is the actual tolerance value. For example, 6 0.000025 sets a tolerance to 6 decimal places, and the default tolerance value is 0.000025.
For integer dimensions, the integer value is 0, and the tolerance is an integer. For example, 0 1 sets a tolerance of 1 for integer dimensions.
A value affects only models created after the tolerance option is specified in the configuration file.
