How to Scale a DXF File Using Two Known Coordinates:

  1. Upload the DXF/DWG file you want to scale and add it to the object list in SkyView. It's important to note that the original file is not affected during the scaling process; a new file is created and added to the object list.

  2. Also, add a CAD file that is correctly georeferenced and contains two known coordinates. If you don’t have such a file, you can use On Demand to purchase property boundaries as a reference.

  3. Select the georeferenced file from the object list and activate it in the scene.

  4. Click the focus icon for the object to center the camera on it in the scene.

  5. Select the file you want to scale from the object list and make it visible by clicking the eye icon. If the file is not visible, click the focus icon to center the camera on the object.

  6. If the object cannot be focused on, a message displaying the object's coordinates will appear. Use the design tool to scale the file correctly using the known coordinates. Click the Scale with Reference Points button.

  7. In the right panel, under Scaling Mode, the option Known Coordinates should be selected.

  8. Specify or click on two known coordinates (A and B) in the georeferenced drawing.

  9. In the right panel, under the Known Coordinates section, enter the N and E coordinates for Point A and Point B, or left-click on the points in the drawing to place them.

  10. Click on two reference points in the file you want to scale and then click the Preview button in the right panel.

  11. You will now see a preview of how the scaling will appear in the scene. Zoom in on the drawing and select the corresponding points to place Point A and Point B in the file you want to scale.

  12. The scale factor is set to 1 by default. This value may need to be adjusted depending on how the drawing was created. For converting between meters and millimeters, set the value to 1000 or 0.001. If you want the file to be scaled automatically based on the reference points, remove the value or set it to 0.

  13. Adjust the opacity of the scaled object in the scene to make it easier to preview the result before confirming the scaling.

  14. To perform the scaling, select Confirm. The scaling process will start, and you will receive a notification when the new file is exported and available in the project's file manager. The file is exported to the same folder as the original, with the suffix *_export_YYYYMMDD_HHMM.dxf. Add the new file to the object list and activate it in the scene.
