# What Are The Geometric Modeler Tolerances?

The geometric modeler works with a set of two tolerances which are defined as follows:

### Point tolerance

Two objects closer than the point tolerance are considered as equal. The point tolerance value is 0.001mm.
Example 1
It is impossible to create a line between two points whose distance is less than the point tolerance.
Example 2
A curve whose distance from a surface is less than the point tolerance can be laid down on this surface (to create a parallel curve for instance).

### Angular tolerance

An edge with a sharpness smaller than the angular tolerance is considered as smooth. The angular tolerance value is 0.5 degree.
Example 1
A shell composed of two faces whose angle along their common edge varies from 0.6 to 1 degree is not considered as smooth. This surface has a sharp edge which can be made smooth by using the EdgeFillet capability.
Example 2
A shell composed of two faces whose angle along their common edge varies from 0.3 to 0.6 degree is not considered as smooth.
