I found that Qcad sometimes changes coordinates or lengths slightly. E.g. when join a line with an arc endpoint, it happens, that when I later import the DXF to Blender, that there is a gap between the arc endpoint and the line (healing required). Also line lengths or angles begin to change during working (translating, mirroing, copying). Has a line been of length 7mm, then it becomes 6.996 mm suddenly.
Haven't yet found out under which circumstances this happens but it makes the DXF unsuitable for importing into Blender, or saying the least, difficult to handle.
I'm seeking for a way to improve the exchange between QCad and Blender. Possibly drop Qcad and use Blender instead? This couldn't be it

Personal I have never experienced that!
That sounds to me to be the answer of you question. Blender's import function changes the dxf coordinates or lengths. Sounds to me it could be a scale / unit converting issue.
It looks like you already encircle the issue. Look on the Blender side for all import option.
We are happy to help you with QCAD but for Blender you have to do your own research or ask in the appropriate Blender forums. Good luck!
