- New methods SetLinearTolerance and SetAngularTolerance have been added in the class ShapeUpgrade_UnifySameDomain. - The algorithm has been modified to consider these tolerances when checking if two faces are same domain. - The draw command unifysamedomain has been changed to accept new parameters. - The internal method MergeSeq has been changed to avoid exception connected with access to unknown key in the data map. Create test case Small correction of test case for issue CR27729
