- error C2491: definition of dllimport static data member not allowed - fixed by "inline" on _mGeometryHandlers - now have unresolved refs in Part - Part and Measure have a...

modified CMakeLists and PreCompiled.h to solve include and linker errors in win local build. Also rebased on main. Changes are here: https://github.com/WandererFan/FreeCAD/tree/gsoc2023_measure

changes to use shared_ptr instead of raw pointers for MeasureInfo and derivatives is here: https://github.com/WandererFan/FreeCAD/tree/gsoc2023_measure

Every measurement type has geometry handlers that know the details of how to get the measurement and what information to return. The initial set is Angle, Area, Distance, Length, Position...

The name getDagKey is not very informative. Is this really getting the document object's unique name?

This applies to the c++ dxf exporter in the Import module. When exporting a sketch to dxf, if the sketch is not on the XY plane, the result is not...

I can export the sketch in two orientations. If I apply the sketch's placement, the dxf looks like the sketch in edit mode. If I only use the placement's axis...

display mode = sketch not in edit viewed in 3d window. multiple selected objects (sketches) are exported individually using each the normal of each sketch.
