Added new operator bim.flip_object that flips the object by flipping two of its axes and keeps the original placement.
Currently it can be found either from F3 search or from Shift-F hotkey for IfcBeam and IfcColumn in BIM tools.
Previously it was conflicting with other possible groups assigned to the object. It's now even more important since we're actively using groups to save search queries.
Example error caused by this issue - during drawing activation if you had 2 IfcGroups on the drawing element:
draiwng's IfcGroup RelatedObjects attribute was updated, then inverse attrtibute `drawing.HasAssignments` order was updated too (DRAWING IfcGroup now would be positioned second after IfcGroup for search query) and it was leading to errors during filtering current drawing annotations
If you compare the results generated by the numeric integration and the approximation, they are very different. The approximation compares will with other software so there is likely a problem with the equation of the clothoid
This is a more general approach than the Taylor Series approximation and is applicable to all the other spiral types. I stubbed out a functor for IfcSecondOrderPolynomialSpiral, but haven't tested it. The purpose is to show the concept.
It wasn't passing the exclude_callback if attribute of the copied element wasn't a tuple, resulting in duplicated named profiles in case if you'd copy a IfcBooleanClippingResult #3810
For example, how copy_deep of IfcProductDefinitionShape with boolean clipping previously would work:
V IfcShapeRepresentation - copied with exlude_callback (part of .Representations[])
V IfcBooleanClippingResult - copied with exlude_callback (part of .Items[])
X IfcExtrudedAreaSolid - copied without exlude_callback becuase it's part of .FirstOperand (not an array) and we have IfcIShapeProfileDef duplicated
Case without booleanclippings:
V IfcShapeRepresentation - copied with exlude_callback (part of .Representations[])
V IfcExtrudedAreaSolid - copied with exlude_callback, since it's part of .Items[], IfcIShapeProfileDef not duplicated
