Design Overlay - PIX4Dcloud Advanced


The Design Overlay tool allows users to easily import and overlay design plans and maps on 2D orthomosaics in PIX4Dcloud Advanced. With the Design Overlay tool, the as-built can be quickly compared with the as-designed to check progress and identify as-built errors easily.

  • The Design Overlay feature is only available on PIX4Dcloud Advanced.
  • The Design Overlay feature is only available for datasets assigned to a site. More information on how to assign a dataset to a site is here.
  • The Design Overlay feature supports images (PDF, JPEG, JPG, and PNG) and DXF files.
  • Multiple files can be uploaded and overlaid in a single project.
  • The Design Overlay is only displayed in the 2D viewer (on top of the orthomosaic and DSM). It can't be visualized on top of the point cloud and 3D mesh.
Information: Once the Design Overlay is added to a dataset within a Site, it is shared with all datasets within the same Site. If the position of a Design Overlay is edited, it will be edited on all datasets within the Site. If a Design Overlay is deleted, it will be deleted on all datasets within the Site.
  • The Design Overlay name can be changed, descriptions and tags can be added to the layer, and its opacity adjusted. These changes won't be reflected in the other datasets on the Site.
  • If multiple files are uploaded, they can be reordered by drag-and-drop.

Import a design file in image format

  1. On the left panel, in correspondence with the Design Overlays layer, click add.png.
  2. Select Image design (PDF, PNG, JPG).
  3. The wizard Image design (PDF, PNG, JPG) opens. To upload a file, select Upload file and browse to the file or drag and drop the file.
    Note: Ensure the file has a PDF (georeferenced or not), JPEG, JPG, or PNG format, and a high resolution for smooth display and zooming.
  4. (Optional): If required, the uploaded file can be replaced by selecting Replace file.
  5. A preview of the file is displayed.
  6. Click Next to continue.
  7. Define two points of reference on your plan, placing the blue and red markers on the image by drag-and-drop. To place markers more precisely or check the markers' placement:
    • Zoom in by scrolling the mouse scroll wheel forwards.
    • Zoom out by scrolling the mouse scroll wheel backward.
    • Pan by holding down the mouse's left button.
  8. Once the two markers are identified, select Next to align the uploaded file on the 2D map.
  9. Align the imported Image design by dragging the two markers to the same points of reference on the 2D orthomosaic. Match red to red and blue to blue.
    Alternatively, manually edit the coordinates of the markers, adjusting their values in the Marker's coordinates.
    • Markers' coordinates should be defined in the project's output coordinate system.
    • If a georeferenced PDF is uploaded, the coordinates are automatically placed using the PDF coordinates.
    • Hit Reset to return to the coordinates of the markers loaded by default.
  10. Once each marker is in the correct position, select Complete to finalize the Image design import process and to return to the project page.
  11. The imported Image design appears on the left panel. It may take a few minutes to process.
    • To enable large image upload without altering the user navigation, PIX4Dcloud Advanced generates tiles from the uploaded file. This may imply that processing can take a few minutes, depending on the file size.
    • A processing icon will be displayed during the tiling process.
  12. (Optional) The existing Image design layer can be re-positioned or replaced by clicking edit.png next to them on the left panel.

Import a design file in DXF format

  1. On the left panel, in correspondence with the Design Overlays layer, click add.png.
  2. Select Vector design (DXF).
  3. The wizard Vector design (DXF) opens. To upload a file, select Upload file and browse the file or drag and drop the file.
  4. On the left panel, the status of the file's import is shown as a percentage under the Design overlays layer.
  5. After the import is complete, the DXF file is displayed on top of the orthomosaic. By default, the layers are enabled but can be switched off for better visibility.
  • The imported DXF file must be in the same coordinate system as the project to be shown as aligned with the orthomosaic and the DSM.
  • Only DXF files that contain 2D information are displayed above the orthomosaic and the DSM.
  • Several DXF files can be imported at the same time.

    Hi, The video does not play on this page -

    CAD Overlay on Pix4Dcloud Advanced

  • Gyula Sólyom

    Can you provide more info on the limitations of georeferenced pdfs? Linear size, number of layers, area, file size?

  • Holden (Pix4D)

    Hi Gyula. These limtations would be more related to the file format ittself rather than Pix4D specifically. Here are some sources that discuss this georeferencedPDF

  • Gyula Sólyom

    Thanks! We have some experience with importing geoJSON and it works up until a few lines, but if we have a more complex file it just simply does not show up in pix4dcloud. So this is not will be the case with geopdf, if we are able to generate the pdf, it will appear?

  • Holden (Pix4D)

    It should appear yes. 

  • Mike Gowan

    Is there a way to create an output file that includes both the superimposed overlay and the underlying orthomosaic map?  I used the screen capture function, but the information on the overlay is a little blurry when I zoom in.  Also, can the color of the overlay lines be changed?  



  • Holden (Pix4D)

    Hi Mike. Currently, there is no high res export feature that will combine these layers. Feel free to leave this as a feature suggestion on the page linked HERE
