|Fixed in Version||6.5.1|
|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
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)

|Test case number||xstp 410 C8|
test.stp (8,407 bytes)
stepcontrol_actorread.cxx (73,333 bytes)
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
Could you please add this case in the test base because this case is special and
it differs from all existent test cases.

Workbench KAS:dev:OCC22238-v1-opt has been created from
stepcontrol_actorread.cxx and compiled on Linux platform.
There are following regressions(/differences) in OCC22238-v1-opt regarding to
Regressions were not found.
