Model exported to PDF format doesn't open and shows only blank page

[michaelguest]

Hello there! I wrote a python script to export the model but for some reason when I open it in PDF it is blank. Please note I am using Adobe Acrobat. I then tried to export manually and it shows up. How come when I export it through script the PDF is blank? I am using the same parameters. Also my model is 200,000 faces. I have attached my code at the bottom thanks!

Hello michaelguest,

Is the chunk where from the model is exported georeferenced?

Hello michaelguest,

I suggest to use the following code sample which defines the viewpoint location and orientation required for the 3D PDF export:

Code: [Select]

chunk = Metashape.app.document.chunk
view = Metashape.Viewpoint()
view.coo = chunk.transform.matrix.mulp(chunk.region.center)
view.rot = chunk.transform.matrix.rotation() * chunk.region.rot
view.mag = chunk.transform.matrix.scale() * chunk.region.size.norm() / (5 * view.height)
chunk.exportModel(path ="D:/test.pdf", format = Metashape.ModelFormatPDF, viewpoint = view)
