step bounding_box weird position

• I'm submitting a ...

  • [X] bug report
  • [ ] feature request

• What is the current behavior? On volmdlr 0.11 I read a step file and the xmin of the bounding_box was 0 In Freecad, it is 0 too on 0.14 I have xmin = -0.004404400000000001 = -4.4mm Thoses mm are important because it seems to not be the reality The step is available in zip file

Is the step the problem or do you have the same issue on other step

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem Avoid reference to other packages

step_file = step.Step.from_stream(step_file_stream) volume_model = step_file.to_volume_model() volume_model.primitives[0].bounding_box.xmin

• What is the expected behavior? To have xmin = 0

• What is the motivation / use case for changing the behavior? Bot dev

• Possible fixes

• Please tell us about your environment: step_check_bounding_box.zip

Hi @MackJoly It is a known issue. The pull request #1106 should solve this issue.

I have tried and have this result! {'xmin': 0.0, 'xmax': 2.2, 'ymin': -1.250000000102, 'ymax': 1.25, 'zmin': 0.0, 'zmax': 0.8, '_size': None, '_octree': None, 'name': ''}
