Converts a Geotif (.tif) elevation raster to a 3D mesh model in DXF format (.dxf). Perfect to convert a raster to TIN and import your topography in your 3D modelling software.
Have you tried all the online tif to DXF converters and none give you the 3D mesh output you are looking for? I made this converter so you can quickly import you topography in your 3D modelling software.
Create an account, upload your geotif raster and select a Z-axis tolerance depending on your use case need for a high fidelity TIN surface. After the conversion is done, we send you the files by email to be downloaded. A free sample DXF can be created to test the output before buying. We also offer the option to upload a KML polygon to extract only a part of the Geotiff.
Our algorithm works by adding triangles to the mesh surface recursively until the mesh surface fits within the given Z-axis tolerance. So if you put a Z-tolerance of 0.5, then you will be guaranteed that the generated surface never strays more than 0.5 units (foot or meters depending on the units of your geotif) away from actual elevation given by the raster. That means you are in control of how detailed you want your mesh versus how big of a file you can handle.

Image set 1: On the left is the hillshade rendering of the Bryce Canyon DEM as seen in QGIS (file size =119Mb). On the right is the 3D model of the same area at full resolution. Mesh files are notoriously big hence why it is hard to find a good file converter and why most online converters are not adapted to this purpose.

Image set 2: On the left, 0.25 meter Z-tolerance (file size = 629Mb). On the right, exact same view but with 1 meter Z-tolerance (file size = 130 Mb)
