Window openings sometimes don't work

[dasviridov]

Loading some of ifc models for houses result models being loaded without window openings. See screenshots of source ifc file in BIM Viewer and the same file in web-ifc-viewer. Source file is attached as well.

Some models I have, do load correctly. Others may have no window openings on ground floor but have openings on first floor.

Happy to help with testing.

@tomvandig, any updates on this issue?

Hi, I'm working on a new bool algorithm, when it's in I will revisit this issue and try to resolve it.

Already pinged agviegas on discord but, for the record, the problem with this file seems to be not boolean subtraction code itself but web-ifc supplying bad argument to boolean subtraction code.
