I think it is a duplicate of How to georeference a dxf?, How to georeference a vector layer with control points?ġ) Using the limits of the Carta Administrativa Oficial de Portugal (shapefile, the projection is EPSG:3763 (ETRS89 / Portugal TM06)) you can georeference the original pdf fileĢ) To georeference a shapefile (it is better to transform your dxf file to a shapefile (3 shapefiles here, points,lines and polygons)), an approach is to use control points, but one point is insufficient and you can find other points using the limits of the precedent shapefile and you can use: Instead of the two axes (X,Y) used with orthogonal drawings, isometric draw-ing are represented in a two dimensional drawing on three axes (X,Y,Z) with 120 between each axis. CAD-Earth allow you to import/export images, objects and terrain meshes between Google Earth and AutoCAD and create dynamic contour lines, profile meshes.
