I want to know if it is possible to switch of the coordinatsystemcoordinate system in QGIS, because I want to use my own values like x,y,z (the results is a 3D-model and the x,y,z axis is represented in cm, so I do not use and do not need gpsGPS coordinates). In the end it is like my own "local coordinatesystem"coordinate system".
Thanks a lot
