Thanks for the tip, @uclaros ; i do have the grass v.rectify algorithm in my Processing Toolbox, but am not quite understanding how to use it.. And the online documentation <https://grass.osgeo.org/grass79/manuals/v.rectify.html> i've found is no great help.
I'm guessing i just need to map a couple of 2D ground control points to the corresponding points on this vector object, in order resize & move it to its proper place. In this project's CRS (EPSG-3763) two opposite corners of the building's roof would be -44371.951,-280480.105 and -44299.756,-280487.420, respectively... But how then would i map these GCPs to the imported vector object (which has no geocoordinate attributes) in such a way that the algorithm can understand what it needs to transform? Any pointers on how to apply that algorithm to this case would be most appreciated! /walt The grass v.rectify algorithm does exactly that, you'll have to manually > collect your gcps though.
