In this short tutorial I will explain how you can convert cartographic maps available in TIFF format to DXF, a vectorial standard available in most CAD software. The final result, nevertheless with some limitations and lacks, allows you a more productivity and improves the quality of design.
If you need a powerful and versatile 3D software not only for modelling and texturing but also for creating interactive applications, you should have to try Blender. Sometimes its interface can appear very different and problematic than typical software, as AutoCAD for example. But with a little of settings and of course patience and time, it's possible to overcome the initial shock and to import own 2D DXF file in this program. Let's see how.
