i want to develop a CAD/BIM Engineering app using Unreal Engine but i need millimetre precision, is it possible to do this with the engine? or only centimetres?
I will need to be able to snap to a millimetre grid for manufacturing and fabrication

Each coordinate is a floating point value, so while 1.0 is 1 cm, 0.1 will be 1 millimeter.
However, you also don’t need to use the Unreal units – in the end, they are just arbitrary numbers. You can say that 1.0 unit is 1 millimeter if you want. Just consistently use that convention everywhere, and nobody will be the wiser.
However, I don’t think Unreal Engine is a good match for a CAD program, or really, for any content creation program.
The reason is that the runtime uses “baked” geometry, and all the mesh import and re-formatting functions live in the editor only, and the editor is not licensed for distribution.
