Summary	0022238: Bug during step file importation
Description	The description copied from forum. Step file is attached. ========================================================== Hi, I'm importing the attached STEP file. The result ought to be a circularly trimmed plane, translated along its normal vector by 2.0 units. But actually the plane's normal is still pointing along the z axis, but the translation is done along the x axis! In line 104 of test.stp, the translation is defined #77=CARTESIAN_POINT('S2->Labor',(0.,0.,2.)); After importing the STEP file in OCC, I took a look at the transformations. The plane's root compound shape reports as the translational part of its TopLoc_Location Position(-2, -0, -0) the TopLoc_Location's rotation matrix on the other hand has rows Row 1(1, 0, 0) Row 2(0, 1, 0) Row 3(0, 0, 1) So obviously the directions x and z are not swapped. The TopLoc_Location contains only a single Datum3d object and the coumpound shape has no superior node, which could be responsible for a xz-swap. When I re-export the file from Open CASCADE to STEP again, it prompts a line 0000016 = CARTESIAN_POINT('',(-2,,0,E+000,0,E+000)); Rhino3d and other CAD programs are correctly importing the file (resulting in a circular trimmed plane, translated along it's normal vector by 2.0 units)

~~gka~~ 2011-05-03 19:49 developer ~0016789	After analysis initial file test.stp in different systems such as: "Rhinoceros 4.0(Evaluation version)", "Creo Elements/Direct Modeling Personal Edition 3.0" was found that assembly for this case was translated incorrectly. Attached corrected file performs translation of assembly the same way as tools listed above.

~~gka~~ 2011-05-03 19:55 developer ~0016790	Dear Igor. Could you please add this case in the test base because this case is special and it differs from all existent test cases.

There are following regressions(/differences) in OCC22238-v1-opt regarding to KAS:dev:products-20110428-opt Regressions were not found. See results in /KASDev/OCCTtests/KAS/dev/OCC22238-v1-opt_13052011/lin See reference results in /QADisk/occttests/results/KAS/dev/products-20110428-opt_29042011/lin See test cases in /QADisk/occttests/tests/ED N.B. In order to launch testing case you can make use the following instructions http://sbu.nnov.opencascade.com/maintenance/main_certification_te.htm
