Requesting pythonocc-core anaconda release to target OpenCascade 7.8.0 to fix issue with BRepBuilderAPI_GTransform #1285

It would be really cool if pythonocc-core could create another anaconda release based on OpenCascade 7.8.0.

I have an open issue with pythonocc-core==7.7.2 that will likely be fixed by using newer OpenCascade C++ code, see OpenCascade forum.

Cross posting the issue here:

scale_transform = gp_GTrsf()
scale_transform.SetVectorialPart(
  gp_Mat(
    1,    0,       0,
    0,    0.1,    0,
    0,    0,       1    )
)
brep_transform_builder = BRepBuilderAPI_GTransform(
    shape, scale_transform, False  # fails too if I use "True" here
)

Raises runtime error:

RuntimeError: Standard_ConstructionErrorgp_GTrsf::Trsf() - non-orthogonal GTrsf raised from method BRepBuilderAPI_GTransform of class BRepBuilderAPI_GTransform

It crashes even when using a no-scaling-matrix with diagonal values all 1.0.

OpenCascade 7.8.0 has not been tagged yet, afaik there are some changes related to memory management, hopefully it wont have too much impact on the python wrapping workflow

OCCT 7.8.0 has been released. Do you have an estimate on when it will be ported to pythonocc?
