Hi Andrea, False origins happens often with local topographical surveys, with also a false altitude origin. Architectural plans are sometimes even more tricky: rotated, or with a centimetric or millimetric scale instead of a metric scale. A way is to transform the data with a CAD software when available. Even then, problems can arise e.g. when rescaling some objects.
I suppose a workaround in your case would be to use the "move" command and to snap to a point drawn at the correct coordinates. This could be cumbersome when there are many layers to edit, which is often the case, unless you import the dxf as a unique layer.... If your data consist merely of point data (no polylines), it should be possible, after conversion of the dxf in a shapefile, to create the X, Y attributes using the field calculator, and to recalculate these attributes with the same tool. In the case of polylines, there is the possibility to extract vertices. But I do not know if there is a possibility to recreate the polylines after the recalculation of the X, Y attributes. Dxf conversion is a complicated subject. The evolution of the capabilities of QGIS in that field is amazing. Many thanks to the developers for that. Hope this helps, Paul Le 13/11/2019 à 14:04, Andrea Peri a écrit :
Hi, We have a dxf containings geograph data in false.origin . I'm searching a solution to put a kind of origin (x,y) to sum to every point of the data. Is possible to set an origin.to <http://origin.to> a dataset in qgis ? Thx.
