Summary0023954: Modeling Algorithms - BRepPrimAPI_MakeRevol fails to recognize a torus case
DescriptionAdaptor3d_SurfaceOfRevolution::GetType() applies wrong logic to recognize a torus case. Instead of a simple case when rotation axis lies in the circle plane (and does not coincide with its center) it attempts to apply more sophisticated logic which apparently never returns torus (with a single exception when
Distance = aRadius + epsilon

Also the logic to compute a point with 0. parameter on a circle is wrong as the circle can have arbitrary orientation.

The torus should be created regardless even if a Distance < aRadius. This would be a lemon-like torus which is well supported by Open CASCADE.

The fix should be straightforward:
    if (!C.Position().IsCoplanar(myAxis, TolConf, TolAng)) {
      return bRet;
    }
    else if(aLin.Distance(aLC) <= TolConf) {
      bRet=GeomAbs_Sphere;
      return bRet;
    }
    else {
      bRet=GeomAbs_Torus;
      return bRet;
    }

However it is not integrated into OCC git - apparently it was tested and declined (based on the comment
//bRet=GeomAbs_Torus;
//return bRet;
//modified by NIZNHY-PKV Thu Feb 24 09:52:29 2011t)

So the OCC team should verify against the #22646 (for which access is denied)

Dear Andrei,

The result seems to be OK on the current MASTER.

 Please check if test case is OK

Small remark!

Result is "surface of revolution" (not Toroidal surface).
Nevertheless, it is not the reason to consider, that it is not valid.

The test case bugs/modalg_5/bug23954 does not conform to the bug description. It must be updated so that the output of each "dump" is checked against toroidal surface type, and presence of SurfaceOfRevolution instead of Toroidal must be considered as an error.

 Test case bugs modalg_5 bug23954 was updated and it'll be pushed to the next IR and integrated to master (marked with TODO, will be modified when correct output will get).
