(AutoCAD, AutoCAD Civil 3D) Import of .tif orthomosaic
The georeferenced GeoTIFF orthomosaic (transparent or non-transparent) that Pix4Dmapper generates can be imported into AutoCAD.
To import orthomosaic:
1. Drag and drop the orthomosaic onto the main view of AutoCAD.
2. Message asking for an insert point, scale factor and rotation angle will appear, press Enter three times.
3. Double-click on the main window to zoom in to the orthomosaic.
4. In command line type GEOREFIMG and press Enter.
5. Select orthomosaic and press Enter.
6. Double-click on the main window to zoom in to the extents of orthomosaic.
In some cases due to the size of orthomosaics (500 MB to 1 GB and more), orthomosaics cannot be loaded into AutoCAD following aforementioned steps. BigTIFF format is used for large orthomosaic (merged tiles) in Pix4D as a it is not read by AutoCAD. In such cases, to open orthomosaic in AutoCAD:
Method A: Load each tile of the orthomosaic one by one in AutoCAD following aforementioned steps.
Method B: Use another third-party software like Quantum GIS (QGIS), an open source application, to save orthomosaic in traditional format.
1. Drag and drop the orthomosaic onto the main view of QGIS.
2. Right-click on the corresponding layer and click Save As...
3. In the dialog Output mode select the Rendered image option.
4. Once exported, drag and drop the new orthomosaic onto the main view of AutoCAD.
5. A message asking for an insert point, scale factor and rotation angle will appear, press Enter three times.
6. Double-click on the main window to zoom in to the orthomosaic.

How can i import an obj file in vector works with all the texture?
Hi Juan,
I'm afraid I don't understand your question. Could you tell me in other words, what do you have in mind?
Thank you very much!

Hello,
I cannot use the Georefimg. Is always giving the message "world file not found". Both files (the Tiff and the TFW has the same name and are both in the same folder).
I took the geotiff file from Pix4D and converted in Qgis with High compression to be able to load it in autocad.
I'm using Civil 3D 2020.
Thanks in advance!
Could you try with the original Pix4D geotiff?
I suggest you contact the Civil 3D support team. We are interested in knowing their comments
Is it possible to upload .Obj files from other programs like 3dsmax, autocad, maya, zbrush, blender to the pix4d 3d models?
Hi Dustin,
If you are using Pix4Dmapper, unfortunately, you cannot upload Obj files. Please find more information here. However, using Pix4Dcloud, you can upload it for visualization. Please visit the website, How to upload results and outputs to Pix4Dcloud, which explains the recommended file formats of OBJ Mesh data.
