  - `m_dTessellationTolerance`

Variables

A3DDouble `A3DCollisionParameterData.``m_dSafetyDistance`
  `A3DDouble`

  It makes possible to identify parts between which a specified distance is not verified.

  The safety distance value has to be greater than `m_dContactLimit`

A3DDouble `A3DCollisionParameterData.``m_dContactLimit`
  `A3DDouble`

  This value defines the upper limit of distances interval in which the parts are judged “in contact”.

  The minimum value for the contact limit 0.1 mm, or can be set to 0. to check only clearance and collision cases.

A3DDouble `A3DCollisionParameterData.``m_dTessellationTolerance`
  `A3DDouble`

  Computation tolerance.

  The minimal value is 0.01 mm. The tolerance value cannot be greater than `m_dContactLimit`.
